+<!--
+Please provide clear motivation for your patch and explain how it improves
+Bitcoin Core user experience or Bitcoin Core developer experience
+significantly:
+
+* Any test improvements or new tests that improve coverage are always welcome.
+* All other changes should have accompanying unit tests (see `src/test/`) or
+  functional tests (see `test/`). Contributors should note which tests cover
+  modified code. If no tests exist for a region of modified code, new tests
+  should accompany the change.
+* Bug fixes are most welcome when they come with steps to reproduce or an
+  explanation of the potential issue as well as reasoning for the way the bug
+  was fixed.
+* Features are welcome, but might be rejected due to design or scope issues.
+  If a feature is based on a lot of dependencies, contributors should first
+  consider building the system outside of Bitcoin Core, if possible.
+* Refactoring changes are only accepted if they are required for a feature or
+  bug fix or otherwise improve developer experience significantly. For example,
+  most "code style" refactoring changes require a thorough explanation why they
+  are useful, what downsides they have and why they *significantly* improve
+  developer experience or avoid serious programming bugs. Note that code style
+  is often a subjective matter. Unless they are explicitly mentioned to be
+  preferred in the [developer notes](/doc/developer-notes.md), stylistic code
+  changes are usually rejected.
+-->
+
+<!--
+Bitcoin Core has a thorough review process and even the most trivial change
+needs to pass a lot of eyes and requires non-zero or even substantial time
+effort to review. There is a huge lack of active reviewers on the project, so
+patches often sit for a long time.

+Contributing to Bitcoin Core
+============================
+
+The Bitcoin Core project operates an open contributor model where anyone is
+welcome to contribute towards development in the form of peer review, testing
+and patches. This document explains the practical process and guidelines for
+contributing.
+
+First, in terms of structure, there is no particular concept of "Bitcoin Core
+developers" in the sense of privileged people. Open source often naturally
+revolves around a meritocracy where contributors earn trust from the developer
+community over time. Nevertheless, some hierarchy is necessary for practical
+purposes. As such, there are repository maintainers who are responsible for
+merging pull requests, the [release cycle](/doc/release-process.md), and
+moderation.
+
+Getting Started
+---------------
+
+New contributors are very welcome and needed.
+
+Reviewing and testing is highly valued and the most effective way you can contribute
+as a new contributor. It also will teach you much more about the code and
+process than opening pull requests. Please refer to the [peer review](#peer-review)
+section below.
+
+Before you start contributing, familiarize yourself with the Bitcoin Core build
+system and tests. Refer to the documentation in the repository on how to build
+Bitcoin Core and how to run the unit tests, functional tests, and fuzz tests.
+
+There are many open issues of varying difficulty waiting to be fixed.
+If you're looking for somewhere to start contributing, check out the
+[good first issue](https://github.com/bitcoin/bitcoin/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
+list or changes that are
+[up for grabs](https://github.com/bitcoin/bitcoin/issues?utf8=%E2%9C%93&q=label%3A%22Up+for+grabs%22).
+Some of them might no longer be applicable. So if you are interested, but
+unsure, you might want to leave a comment on the issue first.
+
+You may also participate in the [Bitcoin Core PR Review Club](https://bitcoincore.reviews/).
+
+### Good First Issue Label
+
+The purpose of the `good first issue` label is to highlight which issues are
+suitable for a new contributor without a deep understanding of the codebase.
+
+However, good first issues can be solved by anyone. If they remain unsolved
+for a longer time, a frequent contributor might address them.
+
+You do not need to request permission to start working on an issue. However,
+you are encouraged to leave a comment if you are planning to work on it. This
+will help other contributors monitor which issues are actively being addressed
+and is also an effective way to request assistance if and when you need it.
+
+Communication Channels
+----------------------
+
+Most communication about Bitcoin Core development happens on IRC, in the
+`#bitcoin-core-dev` channel on Libera Chat. The easiest way to participate on IRC is
+with the web client, [web.libera.chat](https://web.libera.chat/#bitcoin-core-dev). Chat
+history logs can be found
+on [https://www.erisian.com.au/bitcoin-core-dev/](https://www.erisian.com.au/bitcoin-core-dev/)
+and [https://gnusha.org/bitcoin-core-dev/](https://gnusha.org/bitcoin-core-dev/).
+
+Discussion about codebase improvements happens in GitHub issues and pull
+requests.
+
+The developer
+[mailing list](https://groups.google.com/g/bitcoindev)
+should be used to discuss complicated or controversial consensus or P2P protocol changes before working on
+a patch set.
+Archives can be found on [https://gnusha.org/pi/bitcoindev/](https://gnusha.org/pi/bitcoindev/).
+
+
+Contributor Workflow
+--------------------
+
+The codebase is maintained using the "contributor workflow" where everyone
+without exception contributes patch proposals using "pull requests" (PRs). This
+facilitates social contribution, easy testing and peer review.
+
+To contribute a patch, the workflow is as follows:
+
+  1. Fork repository ([only for the first time](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo))
+  1. Create topic branch
+  1. Commit patches
+
+For GUI-related issues or pull requests, the https://github.com/bitcoin-core/gui repository should be used.
+For all other issues and pull requests, the https://github.com/bitcoin/bitcoin node repository should be used.
+
+The master branch for all monotree repositories is identical.
+
+As a rule of thumb, everything that only modifies `src/qt` is a GUI-only pull
+request. However:
+
+* For global refactoring or other transversal changes the node repository
+  should be used.
+* For GUI-related build system changes, the node repository should be used
+  because the change needs review by the build systems reviewers.
+* Changes in `src/interfaces` need to go to the node repository because they
+  might affect other components like the wallet.
+
+For large GUI changes that include build system and interface changes, it is
+recommended to first open a pull request against the GUI repository. When there
+is agreement to proceed with the changes, a pull request with the build system
+and interfaces changes can be submitted to the node repository.
+
+The project coding conventions in the [developer notes](doc/developer-notes.md)
+must be followed.
+
+### Committing Patches
+
+In general, [commits should be atomic](https://en.wikipedia.org/wiki/Atomic_commit#Atomic_commit_convention)
+and diffs should be easy to read. For this reason, do not mix any formatting
+fixes or code moves with actual code changes.
+
+Make sure each individual commit is hygienic: that it builds successfully on its
+own without warnings, errors, regressions, or test failures.
+This means tests must be updated in the same commit that changes the behavior.
+
+Commit messages should be verbose by default consisting of a short subject line
+(50 chars max), a blank line and detailed explanatory text as separate
+paragraph(s), unless the title alone is self-explanatory (like "Correct typo
+in init.cpp") in which case a single title line is sufficient. Commit messages should be
+helpful to people reading your code in the future, so explain the reasoning for
+your decisions. Further explanation [here](https://cbea.ms/git-commit/).
+
+If a particular commit references another issue, please add the reference. For
+example: `refs #1234` or `fixes #4321`. Using the `fixes` or `closes` keywords
+will cause the corresponding issue to be closed when the pull request is merged.
+
+Commit messages should never contain any `@` mentions (usernames prefixed with "@").
+
+Please refer to the [Git manual](https://git-scm.com/doc) for more information
+about Git.
+
+  - Push changes to your fork
+  - Create pull request
+
+### Creating the Pull Request
+
+The title of the pull request should be prefixed by the component or area that
+the pull request affects. Valid areas as:
+
+  - `consensus` for changes to consensus critical code
+  - `doc` for changes to the documentation
+  - `qt` or `gui` for changes to bitcoin-qt
+  - `log` for changes to log messages
+  - `mining` for changes to the mining code
+  - `net` or `p2p` for changes to the peer-to-peer network code
+  - `refactor` for structural changes that do not change behavior
+  - `rpc`, `rest` or `zmq` for changes to the RPC, REST or ZMQ APIs
+  - `contrib` or `cli` for changes to the scripts and tools
+  - `test`, `qa` or `ci` for changes to the unit tests, QA tests or CI code
+  - `util` or `lib` for changes to the utils or libraries
+  - `wallet` for changes to the wallet code
+  - `build` for changes to CMake
+  - `guix` for changes to the GUIX reproducible builds
+
+Examples:
+
+    consensus: Add new opcode for BIP-XXXX OP_CHECKAWESOMESIG
+    net: Automatically create onion service, listen on Tor
+    qt: Add feed bump button
+    log: Fix typo in log message
+
+The body of the pull request should contain sufficient description of *what* the
+patch does, and even more importantly, *why*, with justification and reasoning.
+You should include references to any discussions (for example, other issues or
+mailing list discussions).
+
+The description for a new pull request should not contain any `@` mentions. The
+PR description will be included in the commit message when the PR is merged and
+any users mentioned in the description will be annoyingly notified each time a
+fork of Bitcoin Core copies the merge. Instead, make any username mentions in a
+subsequent comment to the PR.
+
+### Translation changes
+
+Note that translations should not be submitted as pull requests. Please see
+[Translation Process](https://github.com/bitcoin/bitcoin/blob/master/doc/translation_process.md)
+for more information on helping with translations.
+
+### Work in Progress Changes and Requests for Comments
+
+If a pull request is not to be considered for merging (yet), please
+prefix the title with [WIP] or use [Tasks Lists](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#task-lists)
+in the body of the pull request to indicate tasks are pending.
+
+### Address Feedback
+
+At this stage, one should expect comments and review from other contributors. You
+can add more commits to your pull request by committing them locally and pushing
+to your fork.
+
+You are expected to reply to any review comments before your pull request is
+merged. You may update the code or reject the feedback if you do not agree with
+it, but you should express so in a reply. If there is outstanding feedback and
+you are not actively working on it, your pull request may be closed.
+
+Please refer to the [peer review](#peer-review) section below for more details.
+
+### Squashing Commits
+
+If your pull request contains fixup commits (commits that change the same line of code repeatedly) or too fine-grained
+commits, you may be asked to [squash](https://git-scm.com/docs/git-rebase#_interactive_mode) your commits
+before it will be reviewed. The basic squashing workflow is shown below.
+
+    git checkout your_branch_name
+    git rebase -i HEAD~n
+    # n is normally the number of commits in the pull request.
+    # Set commits (except the one in the first line) from 'pick' to 'squash', save and quit.
+    # On the next screen, edit/refine commit messages.
+    # Save and quit.
+    git push -f # (force push to GitHub)
+
+Please update the resulting commit message, if needed. It should read as a
+coherent message. In most cases, this means not just listing the interim
+commits.
+
+If your change contains a merge commit, the above workflow may not work and you
+will need to remove the merge commit first. See the next section for details on
+how to rebase.
+
+Please refrain from creating several pull requests for the same change.
+Use the pull request that is already open (or was created earlier) to amend
+changes. This preserves the discussion and review that happened earlier for
+the respective change set.
+
+The length of time required for peer review is unpredictable and will vary from
+pull request to pull request.
+
+### Rebasing Changes
+
+When a pull request conflicts with the target branch, you may be asked to rebase it on top of the current target branch.
+
+    git fetch https://github.com/bitcoin/bitcoin  # Fetch the latest upstream commit
+    git rebase FETCH_HEAD  # Rebuild commits on top of the new base
+
+This project aims to have a clean git history, where code changes are only made in non-merge commits. This simplifies
+auditability because merge commits can be assumed to not contain arbitrary code changes. Merge commits should be signed,
+and the resulting git tree hash must be deterministic and reproducible. The script in
+[/contrib/verify-commits](/contrib/verify-commits) checks that.
+
+After a rebase, reviewers are encouraged to sign off on the force push. This should be relatively straightforward with
+the `git range-diff` tool explained in the [productivity
+notes](/doc/productivity.md#diff-the-diffs-with-git-range-diff). To avoid needless review churn, maintainers will
+generally merge pull requests that received the most review attention first.
+
+Pull Request Philosophy
+-----------------------
+
+Patchsets should always be focused. For example, a pull request could add a
+feature, fix a bug, or refactor code; but not a mixture. Please also avoid super
+pull requests which attempt to do too much, are overly large, or overly complex
+as this makes review difficult.
+
+
+### Features
+
+When adding a new feature, thought must be given to the long term technical debt
+and maintenance that feature may require after inclusion. Before proposing a new
+feature that will require maintenance, please consider if you are willing to
+maintain it (including bug fixing). If features get orphaned with no maintainer
+in the future, they may be removed by the Repository Maintainer.
+
+
+### Refactoring
+
+Refactoring is a necessary part of any software project's evolution. The
+following guidelines cover refactoring pull requests for the project.
+
+There are three categories of refactoring: code-only moves, code style fixes, and
+code refactoring. In general, refactoring pull requests should not mix these
+three kinds of activities in order to make refactoring pull requests easy to
+review and uncontroversial. In all cases, refactoring PRs must not change the
+behaviour of code within the pull request (bugs must be preserved as is).
+
+Project maintainers aim for a quick turnaround on refactoring pull requests, so
+where possible keep them short, uncomplex and easy to verify.
+
+Pull requests that refactor the code should not be made by new contributors. It
+requires a certain level of experience to know where the code belongs to and to
+understand the full ramification (including rebase effort of open pull requests).
+
+Trivial pull requests or pull requests that refactor the code with no clear
+benefits may be immediately closed by the maintainers to reduce unnecessary
+workload on reviewing.
+
+
+"Decision Making" Process
+-------------------------
+
+The following applies to code changes to the Bitcoin Core project (and related
+projects such as libsecp256k1), and is not to be confused with overall Bitcoin
+Network Protocol consensus changes.
+
+Whether a pull request is merged into Bitcoin Core rests with the project merge
+maintainers.
+
+Maintainers will take into consideration if a patch is in line with the general
+principles of the project; meets the minimum standards for inclusion; and will
+judge the general consensus of contributors.
+
+In general, all pull requests must:
+
+  - Have a clear use case, fix a demonstrable bug or serve the greater good of
+    the project (for example refactoring for modularisation);
+  - Be well peer-reviewed;
+  - Have unit tests, functional tests, and fuzz tests, where appropriate;
+  - Follow code style guidelines ([C++](doc/developer-notes.md), [functional tests](test/functional/README.md));
+  - Not break the existing test suite;
+  - Where bugs are fixed, where possible, there should be unit tests
+    demonstrating the bug and also proving the fix. This helps prevent regression.
+  - Change relevant comments and documentation when behaviour of code changes.
+
+Patches that change Bitcoin consensus rules are considerably more involved than
+normal because they affect the entire ecosystem and so must be preceded by
+extensive mailing list discussions and have a numbered BIP. While each case will
+be different, one should be prepared to expend more time and effort than for
+other kinds of patches because of increased peer review and consensus building
+requirements.
+
+
+### Peer Review
+
+Anyone may participate in peer review which is expressed by comments in the pull
+request. Typically reviewers will review the code for obvious errors, as well as
+test out the patch set and opine on the technical merits of the patch. Project
+maintainers take into account the peer review when determining if there is
+consensus to merge a pull request (remember that discussions may have been
+spread out over GitHub, mailing list and IRC discussions).
+
+Code review is a burdensome but important part of the development process, and
+as such, certain types of pull requests are rejected. In general, if the
+**improvements** do not warrant the **review effort** required, the PR has a
+high chance of being rejected. It is up to the PR author to convince the
+reviewers that the changes warrant the review effort, and if reviewers are
+"Concept NACK'ing" the PR, the author may need to present arguments and/or do
+research backing their suggested changes.
+
+#### Conceptual Review
+
+A review can be a conceptual review, where the reviewer leaves a comment
+ * `Concept (N)ACK`, meaning "I do (not) agree with the general goal of this pull
+   request",
+ * `Approach (N)ACK`, meaning `Concept ACK`, but "I do (not) agree with the
+   approach of this change".
+
+A `NACK` needs to include a rationale why the change is not worthwhile.
+NACKs without accompanying reasoning may be disregarded.
+
+#### Code Review
+
+After conceptual agreement on the change, code review can be provided. A review
+begins with `ACK BRANCH_COMMIT`, where `BRANCH_COMMIT` is the top of the PR
+branch, followed by a description of how the reviewer did the review. The
+following language is used within pull request comments:
+
+  - "I have tested the code", involving change-specific manual testing in
+    addition to running the unit, functional, or fuzz tests, and in case it is
+    not obvious how the manual testing was done, it should be described;
+  - "I have not tested the code, but I have reviewed it and it looks
+    OK, I agree it can be merged";
+  - A "nit" refers to a trivial, often non-blocking issue.
+
+Project maintainers reserve the right to weigh the opinions of peer reviewers
+using common sense judgement and may also weigh based on merit. Reviewers that
+have demonstrated a deeper commitment and understanding of the project over time
+or who have clear domain expertise may naturally have more weight, as one would
+expect in all walks of life.
+
+Where a patch set affects consensus-critical code, the bar will be much
+higher in terms of discussion and peer review requirements, keeping in mind that
+mistakes could be very costly to the wider community. This includes refactoring
+of consensus-critical code.
+
+Where a patch set proposes to change the Bitcoin consensus, it must have been
+discussed extensively on the mailing list and IRC, be accompanied by a widely
+discussed BIP and have a generally widely perceived technical consensus of being
+a worthwhile change based on the judgement of the maintainers.
+
+### Finding Reviewers
+
+As most reviewers are themselves developers with their own projects, the review
+process can be quite lengthy, and some amount of patience is required. If you find
+that you've been waiting for a pull request to be given attention for several
+months, there may be a number of reasons for this, some of which you can do something
+about:
+
+  - It may be because of a feature freeze due to an upcoming release. During this time,
+    only bug fixes are taken into consideration. If your pull request is a new feature,
+    it will not be prioritized until after the release. Wait for the release.
+  - It may be because the changes you are suggesting do not appeal to people. Rather than
+    nits and critique, which require effort and means they care enough to spend time on your
+    contribution, thundering silence is a good sign of widespread (mild) dislike of a given change
+    (because people don't assume *others* won't actually like the proposal). Don't take
+    that personally, though! Instead, take another critical look at what you are suggesting
+    and see if it: changes too much, is too broad, doesn't adhere to the
+    [developer notes](doc/developer-notes.md), is dangerous or insecure, is messily written, etc.
+    Identify and address any of the issues you find. Then ask e.g. on IRC if someone could give
+    their opinion on the concept itself.
+  - It may be because your code is too complex for all but a few people, and those people
+    may not have realized your pull request even exists. A great way to find people who
+    are qualified and care about the code you are touching is the
+    [Git Blame feature](https://docs.github.com/en/repositories/working-with-files/using-files/viewing-and-understanding-files). Simply
+    look up who last modified the code you are changing and see if you can find
+    them and give them a nudge. Don't be incessant about the nudging, though.
+  - Finally, if all else fails, ask on IRC or elsewhere for someone to give your pull request
+    a look. If you think you've been waiting for an unreasonably long time (say,
+    more than a month) for no particular reason (a few lines changed, etc.),
+    this is totally fine. Try to return the favor when someone else is asking
+    for feedback on their code, and the universe balances out.
+  - Remember that the best thing you can do while waiting is give review to others!
+
+
+Backporting
+-----------
+
+Security and bug fixes can be backported from `master` to release
+branches.
+Maintainers will do backports in batches and
+use the proper `Needs backport (...)` labels
+when needed (the original author does not need to worry about it).
+
+A backport should contain the following metadata in the commit body:
+
+```
+Github-Pull: #<PR number>
+Rebased-From: <commit hash of the original commit>
+```
+
+Have a look at [an example backport PR](
+https://github.com/bitcoin/bitcoin/pull/16189).
+
+Also see the [backport.py script](
+https://github.com/bitcoin-core/bitcoin-maintainer-tools#backport).

+Bitcoin Core integration/staging tree
+=====================================
+
+https://bitcoincore.org
+
+For an immediately usable, binary version of the Bitcoin Core software, see
+https://bitcoincore.org/en/download/.
+
+What is Bitcoin Core?
+---------------------
+
+Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully
+validate blocks and transactions. It also includes a wallet and graphical user
+interface, which can be optionally built.
+
+Further information about Bitcoin Core is available in the [doc folder](/doc).
+
+License
+-------
+
+Bitcoin Core is released under the terms of the MIT license. See [COPYING](COPYING) for more
+information or see https://opensource.org/license/MIT.
+
+Development Process
+-------------------
+
+The `master` branch is regularly built (see `doc/build-*.md` for instructions) and tested, but it is not guaranteed to be
+completely stable. [Tags](https://github.com/bitcoin/bitcoin/tags) are created
+regularly from release branches to indicate new official, stable release versions of Bitcoin Core.
+
+The https://github.com/bitcoin-core/gui repository is used exclusively for the
+development of the GUI. Its master branch is identical in all monotree
+repositories. Release branches and tags do not exist, so please do not fork
+that repository unless it is for development reasons.
+
+The contribution workflow is described in [CONTRIBUTING.md](CONTRIBUTING.md)
+and useful hints for developers can be found in [doc/developer-notes.md](doc/developer-notes.md).
+
+Testing
+-------
+
+Testing and code review is the bottleneck for development; we get more pull
+requests than we can review and test on short notice. Please be patient and help out by testing
+other people's pull requests, and remember this is a security-critical project where any mistake might cost people
+lots of money.
+
+### Automated Testing
+
+Developers are strongly encouraged to write [unit tests](src/test/README.md) for new code, and to
+submit new unit tests for old code. Unit tests can be compiled and run
+(assuming they weren't disabled during the generation of the build system) with: `ctest`. Further details on running
+and extending unit tests can be found in [/src/test/README.md](/src/test/README.md).
+
+There are also [regression and integration tests](/test), written
+in Python.
+These tests can be run (if the [test dependencies](/test) are installed) with: `build/test/functional/test_runner.py`
+(assuming `build` is your build directory).
+
+The CI (Continuous Integration) systems make sure that every pull request is tested on Windows, Linux, and macOS.
+The CI must pass on all commits before merge to avoid unrelated CI failures on new pull requests.
+
+### Manual Quality Assurance (QA) Testing
+
+Changes should be tested by somebody other than the developer who wrote the
+code. This is especially important for large or high-risk changes. It is useful
+to add a test plan to the pull request description if testing the changes is
+not straightforward.
+
+Translations
+------------
+
+Changes to translations as well as new translations can be submitted to
+[Bitcoin Core's Transifex page](https://explore.transifex.com/bitcoin/bitcoin/).
+
+Translations are periodically pulled from Transifex and merged into the git repository. See the
+[translation process](doc/translation_process.md) for details on how this works.
+
+**Important**: We do not accept translation changes as GitHub pull requests because the next
+pull from Transifex would automatically overwrite them again.

+# CI Scripts
+
+This directory contains scripts for each build step in each build stage.
+
+## Running a Stage Locally
+
+Be aware that the tests will be built and run in-place, so please run at your own risk.
+If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
+
+The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory.
+While it should be fine to run
+the ci system locally on your development box, the ci scripts can generally be assumed to have received less review and
+testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci
+system in a virtual machine with a Linux operating system of your choice.
+
+To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
+requires `bash`, `docker`, and `python3` to be installed. To run on different architectures than the host `qemu` is also required. To install all requirements on Ubuntu, run
+
+```
+sudo apt install bash docker.io python3 qemu-user-static
+```
+
+For some sanitizer builds, the kernel's address-space layout randomization
+(ASLR) entropy can cause sanitizer shadow memory mappings to fail. When running
+the CI locally you may need to reduce that entropy by running:
+
+```
+sudo sysctl -w vm.mmap_rnd_bits=28
+```
+
+It is recommended to run the ci system in a clean env. To run the test stage
+with a specific configuration,
+
+```
+env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'
+```
+
+## Configurations
+
+The test files (`FILE_ENV`) are constructed to test a wide range of
+configurations, rather than a single pass/fail. This helps to catch build
+failures and logic errors that present on platforms other than the ones the
+author has tested.
+
+Some builders use the dependency-generator in `./depends`, rather than using
+the system package manager to install build dependencies. This guarantees that
+the tester is using the same versions as the release builds, which also use
+`./depends`.
+
+It is also possible to force a specific configuration without modifying the
+file. For example,
+
+```
+env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'
+```
+
+The files starting with `0n` (`n` greater than 0) are the scripts that are run
+in order.
+
+## Cache
+
+In order to avoid rebuilding all dependencies for each build, the binaries are
+cached and reused when possible. Changes in the dependency-generator will
+trigger cache-invalidation and rebuilds as necessary.
+
+## Configuring a repository for CI
+
+### Primary repository
+
+To configure the primary repository, follow these steps:
+
+1. Register with [Cirrus Runners](https://cirrus-runners.app/) and purchase runners.
+2. Install the Cirrus Runners GitHub app against the GitHub organization.
+3. Enable organisation-level runners to be used in public repositories:
+   1. `Org settings -> Actions -> Runner Groups -> Default -> Allow public repos`
+4. Permit the following actions to run:
+   1. cirruslabs/cache/restore@\*
+   1. cirruslabs/cache/save@\*
+   1. docker/setup-buildx-action@\*
+   1. actions/github-script@\*
+
+### Forked repositories
+
+When used in a fork the CI will run on GitHub's free hosted runners by default.
+In this case, due to GitHub's 10GB-per-repo cache size limitations caches will be frequently evicted and missed, but the workflows will run (slowly).
+
+It is also possible to use your own Cirrus Runners in your own fork with an appropriate patch to the `REPO_USE_CIRRUS_RUNNERS` variable in ../.github/workflows/ci.yml
+NB that Cirrus Runners only work at an organisation level, therefore in order to use your own Cirrus Runners, *the fork must be within your own organisation*.

+retry - The command line retry tool
+------------------------------------------
+
+Retry any shell command with exponential backoff or constant delay.
+
+### Instructions
+
+Install:
+
+retry is a shell script, so drop it somewhere and make sure it's added to your $PATH. Or you can use the following one-liner:
+
+```sh
+sudo sh -c "curl https://raw.githubusercontent.com/kadwanev/retry/master/retry -o /usr/local/bin/retry && chmod +x /usr/local/bin/retry"
+```
+
+If you're on OS X, retry is also on Homebrew:
+
+```
+brew pull 27283
+brew install retry
+```
+Not popular enough for homebrew-core. Please star this project to help.
+
+### Usage
+
+Help:
+
+`retry -?`
+
+    Usage: retry [options] -- execute command
+        -h, -?, --help
+        -v, --verbose                    Verbose output
+        -t, --tries=#                    Set max retries: Default 10
+        -s, --sleep=secs                 Constant sleep amount (seconds)
+        -m, --min=secs                   Exponential Backoff: minimum sleep amount (seconds): Default 0.3
+        -x, --max=secs                   Exponential Backoff: maximum sleep amount (seconds): Default 60
+        -f, --fail="script +cmds"        Fail Script: run in case of final failure
+
+### Examples
+
+No problem:
+
+`retry echo u work good`
+
+    u work good
+
+Test functionality:
+
+`retry 'echo "y u no work"; false'`
+
+    y u no work
+    Before retry #1: sleeping 0.3 seconds
+    y u no work
+    Before retry #2: sleeping 0.6 seconds
+    y u no work
+    Before retry #3: sleeping 1.2 seconds
+    y u no work
+    Before retry #4: sleeping 2.4 seconds
+    y u no work
+    Before retry #5: sleeping 4.8 seconds
+    y u no work
+    Before retry #6: sleeping 9.6 seconds
+    y u no work
+    Before retry #7: sleeping 19.2 seconds
+    y u no work
+    Before retry #8: sleeping 38.4 seconds
+    y u no work
+    Before retry #9: sleeping 60.0 seconds
+    y u no work
+    Before retry #10: sleeping 60.0 seconds
+    y u no work
+    etc..
+
+Limit retries:
+
+`retry -t 4 'echo "y u no work"; false'`
+
+    y u no work
+    Before retry #1: sleeping 0.3 seconds
+    y u no work
+    Before retry #2: sleeping 0.6 seconds
+    y u no work
+    Before retry #3: sleeping 1.2 seconds
+    y u no work
+    Before retry #4: sleeping 2.4 seconds
+    y u no work
+    Retries exhausted
+
+Bad command:
+
+`retry poop`
+
+    bash: poop: command not found
+
+Fail command:
+
+`retry -t 3 -f 'echo "oh poopsickles"' 'echo "y u no work"; false'`
+
+    y u no work
+    Before retry #1: sleeping 0.3 seconds
+    y u no work
+    Before retry #2: sleeping 0.6 seconds
+    y u no work
+    Before retry #3: sleeping 1.2 seconds
+    y u no work
+    Retries exhausted, running fail script
+    oh poopsickles
+
+Last attempt passed:
+
+`retry -t 3 -- 'if [ $RETRY_ATTEMPT -eq 3 ]; then echo Passed at attempt $RETRY_ATTEMPT; true; else echo Failed at attempt $RETRY_ATTEMPT; false; fi;'`
+
+    Failed at attempt 0
+    Before retry #1: sleeping 0.3 seconds
+    Failed at attempt 1
+    Before retry #2: sleeping 0.6 seconds
+    Failed at attempt 2
+    Before retry #3: sleeping 1.2 seconds
+    Passed at attempt 3
