 Contributing code to matrix-js-sdk
 ==================================
 
-Everyone is welcome to contribute code to matrix-js-sdk, provided that they are
-willing to license their contributions under the same license as the project
-itself. We follow a simple 'inbound=outbound' model for contributions: the act
-of submitting an 'inbound' contribution means that the contributor agrees to
-license the code under the same terms as the project's overall 'outbound'
-license - in this case, Apache Software License v2 (see
-[LICENSE](LICENSE)).
+matrix-js-sdk follows the same pattern as https://github.com/vector-im/element-web/blob/develop/CONTRIBUTING.md
 
-How to contribute
------------------
-
-The preferred and easiest way to contribute changes to the project is to fork
-it on github, and then create a pull request to ask us to pull your changes
-into our repo (https://help.github.com/articles/using-pull-requests/)
-
-We use GitHub's pull request workflow to review the contribution, and either
-ask you to make any refinements needed or merge it and make them ourselves.
-
-Things that should go into your PR description:
- * A changelog entry in the `Notes` section (see below)
- * References to any bugs fixed by the change (in GitHub's `Fixes` notation)
- * Describe the why and what is changing in the PR description so it's easy for
-   onlookers and reviewers to onboard and context switch. This information is
-   also helpful when we come back to look at this in 6 months and ask "why did
-   we do it like that?" we have a chance of finding out.
-      * Why didn't it work before? Why does it work now? What use cases does it
-        unlock?
-      * If you find yourself adding information on how the code works or why you
-        chose to do it the way you did, make sure this information is instead
-        written as comments in the code itself.
-      * Sometimes a PR can change considerably as it is developed. In this case,
-        the description should be updated to reflect the most recent state of
-        the PR. (It can be helpful to retain the old content under a suitable
-        heading, for additional context.)
- * Include both **before** and **after** screenshots to easily compare and discuss
-   what's changing.
- * Include a step-by-step testing strategy so that a reviewer can check out the
-   code locally and easily get to the point of testing your change.
- * Add comments to the diff for the reviewer that might help them to understand
-   why the change is necessary or how they might better understand and review it.
-
-We rely on information in pull request to populate the information that goes
-into the changelogs our users see, both for the JS SDK itself and also for some
-projects based on it. This is picked up from both labels on the pull request and
-the `Notes:` annotation in the description. By default, the PR title will be
-used for the changelog entry, but you can specify more options, as follows.
-
-To add a longer, more detailed description of the change for the changelog:
-
-
-*Fix llama herding bug*
-
-```
-Notes: Fix a bug (https://github.com/matrix-org/notaproject/issues/123) where the 'Herd' button would not herd more than 8 Llamas if the moon was in the waxing gibbous phase
-```
-
-For some PRs, it's not useful to have an entry in the user-facing changelog (this is
-the default for PRs labelled with `T-Task`):
-
-*Remove outdated comment from `Ungulates.ts`*
-```
-Notes: none
-```
-
-Sometimes, you're fixing a bug in a downstream project, in which case you want
-an entry in that project's changelog. You can do that too:
-
-*Fix another herding bug*
-```
-Notes: Fix a bug where the `herd()` function would only work on Tuesdays
-element-web notes: Fix a bug where the 'Herd' button only worked on Tuesdays
-```
-
-This example is for Element Web. You can specify:
- * matrix-react-sdk
- * element-web
- * element-desktop
-
-If your PR introduces a breaking change, use the `Notes` section in the same
-way, additionally adding the `X-Breaking-Change` label (see below). There's no need
-to specify in the notes that it's a breaking change - this will be added
-automatically based on the label - but remember to tell the developer how to
-migrate:
-
-*Remove legacy class*
-
-```
-Notes: Remove legacy `Camelopard` class. `Giraffe` should be used instead.
-```
-
-Other metadata can be added using labels.
- * `X-Breaking-Change`: A breaking change - adding this label will mean the change causes a *major* version bump.
- * `T-Enhancement`: A new feature - adding this label will mean the change causes a *minor* version bump.
- * `T-Defect`: A bug fix (in either code or docs).
- * `T-Task`: No user-facing changes, eg. code comments, CI fixes, refactors or tests. Won't have a changelog entry unless you specify one.
-
-If you don't have permission to add labels, your PR reviewer(s) can work with you
-to add them: ask in the PR description or comments.
-
-We use continuous integration, and all pull requests get automatically tested:
-if your change breaks the build, then the PR will show that there are failed
-checks, so please check back after a few minutes.
-
-Tests
------
-Your PR should include tests.
-
-For new user facing features in `matrix-react-sdk` or `element-web`, you
-must include:
-
-1. Comprehensive unit tests written in Jest. These are located in `/test`.
-2. "happy path" end-to-end tests.
-   These are located in `/test/end-to-end-tests` in `matrix-react-sdk`, and
-   are run using `element-web`. Ideally, you would also include tests for edge
-   and error cases.
-
-Unit tests are expected even when the feature is in labs. It's good practice
-to write tests alongside the code as it ensures the code is testable from
-the start, and gives you a fast feedback loop while you're developing the
-functionality. End-to-end tests should be added prior to the feature
-leaving labs, but don't have to be present from the start (although it might
-be beneficial to have some running early, so you can test things faster).
-
-For bugs in those repos, your change must include at least one unit test or
-end-to-end test; which is best depends on what sort of test most concisely
-exercises the area.
-
-Changes to `matrix-js-sdk` must be accompanied by unit tests written in Jest.
-These are located in `/spec/`.
-
-When writing unit tests, please aim for a high level of test coverage
-for new code - 80% or greater. If you cannot achieve that, please document
-why it's not possible in your PR.
-
-Some sections of code are not sensible to add coverage for, such as those
-which explicitly inhibit noisy logging for tests. Which can be hidden using
-an istanbul magic comment as [documented here][1]. See example:
-```javascript
-/* istanbul ignore if */
-if (process.env.NODE_ENV !== "test") {
-    logger.error("Log line that is noisy enough in tests to want to skip");
-}
-```
-
-Tests validate that your change works as intended and also document
-concisely what is being changed. Ideally, your new tests fail
-prior to your change, and succeed once it has been applied. You may
-find this simpler to achieve if you write the tests first.
-
-If you're spiking some code that's experimental and not being used to support
-production features, exceptions can be made to requirements for tests.
-Note that tests will still be required in order to ship the feature, and it's
-strongly encouraged to think about tests early in the process, as adding
-tests later will become progressively more difficult.
-
-If you're not sure how to approach writing tests for your change, ask for help
-in [#element-dev](https://matrix.to/#/#element-dev:matrix.org).
-
-Code style
-----------
-The js-sdk aims to target TypeScript/ES6. All new files should be written in
-TypeScript and existing files should use ES6 principles where possible.
-
-Members should not be exported as a default export in general - it causes problems
-with the architecture of the SDK (index file becomes less clear) and could
-introduce naming problems (as default exports get aliased upon import). In
-general, avoid using `export default`.
-
-The remaining code-style for matrix-js-sdk is not formally documented, but
-contributors are encouraged to read the
-[code style document for matrix-react-sdk](https://github.com/matrix-org/matrix-react-sdk/blob/master/code_style.md)
-and follow the principles set out there.
-
-Please ensure your changes match the cosmetic style of the existing project,
-and ***never*** mix cosmetic and functional changes in the same commit, as it
-makes it horribly hard to review otherwise.
-
-Attribution
------------
-Everyone who contributes anything to Matrix is welcome to be listed in the
-AUTHORS.rst file for the project in question. Please feel free to include a
-change to AUTHORS.rst in your pull request to list yourself and a short
-description of the area(s) you've worked on. Also, we sometimes have swag to
-give away to contributors - if you feel that Matrix-branded apparel is missing
-from your life, please mail us your shipping address to matrix at matrix.org
-and we'll try to fix it :)

-Sign off
---------
-In order to have a concrete record that your contribution is intentional
-and you agree to license it under the same terms as the project's license, we've
-adopted the same lightweight approach that the Linux Kernel
-(https://www.kernel.org/doc/Documentation/SubmittingPatches), Docker
-(https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
-projects use: the DCO (Developer Certificate of Origin:
-http://developercertificate.org/). This is a simple declaration that you wrote
-the contribution or otherwise have the right to contribute it to Matrix:
-

-license document, but changing it is not allowed.
-
-Developer's Certificate of Origin 1.1
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the open source license
-    indicated in the file; or
-
-(b) The contribution is based upon previous work that, to the best
-    of my knowledge, is covered under an appropriate open source
-    license and I have the right under that license to submit that
-    work with modifications, whether created in whole or in part
-    by me, under the same open source license (unless I am
-    permitted to submit under a different license), as indicated
-    in the file; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a), (b) or (c) and I have not modified
-    it.
-
-(d) I understand and agree that this project and the contribution
-    are public and that a record of the contribution (including all
-    personal information I submit with it, including my sign-off) is
-    maintained indefinitely and may be redistributed consistent with
-    this project or the open source license(s) involved.
-```
-
-If you agree to this for your contribution, then all that's needed is to
-include the line in your commit or pull request comment:
-
-```
-Signed-off-by: Your Name <your@email.example.org>
-```
-
-We accept contributions under a legally identifiable name, such as your name on
-government documentation or common-law names (names claimed by legitimate usage
-or repute). Unfortunately, we cannot accept anonymous contributions at this
-time.
-
-Git allows you to add this signoff automatically when using the `-s` flag to
-`git commit`, which uses the name and email set in your `user.name` and
-`user.email` git configs.
-
-If you forgot to sign off your commits before making your pull request and are
-on Git 2.17+ you can mass signoff using rebase:
-
-```
-git rebase --signoff origin/develop
-```
-
-Review expectations
-===================
-
-See https://github.com/vector-im/element-meta/wiki/Review-process
-
-
-Merge Strategy
-==============
-
-The preferred method for merging pull requests is squash merging to keep the
-commit history trim, but it is up to the discretion of the team member merging
-the change. We do not support rebase merges due to `allchange` being unable to
-handle them. When merging make sure to leave the default commit title, or 
-at least leave the PR number at the end in brackets like by default.
-When stacking pull requests, you may wish to do the following:
-
-1. Branch from develop to your branch (branch1), push commits onto it and open a pull request
-2. Branch from your base branch (branch1) to your work branch (branch2), push commits and open a pull request configuring the base to be branch1, saying in the description that it is based on your other PR.
-3. Merge the first PR using a merge commit otherwise your stacked PR will need a rebase. Github will automatically adjust the base branch of your other PR to be develop.
