+Visit [Hacking Arvados](https://dev.arvados.org/projects/arvados/wiki/Hacking) for
+detailed information about setting up an Arvados development
+environment, development process, [coding standards](https://dev.arvados.org/projects/arvados/wiki/Coding_Standards), and notes about specific components.
+
+If you wish to build the Arvados documentation from a local git clone, see
+[doc/README.textile](doc/README.textile) for instructions.
+
+# Pull requests
+
+The preferred method for making contributions is through Github pull requests.
+
+This is the general contribution process:
+
+1. Fork the Arvados repository using the Github "Fork" button
+2. Clone your fork, make your changes, commit to your fork.
+3. Every commit message must have a DCO sign-off and every file must have a SPDX license (see below).
+4. Add yourself to the [AUTHORS](AUTHORS) file
+5. When your fork is ready, through Github, Create a Pull Request against `arvados:main`
+6. Notify the core team about your pull request through the [Arvados development
+channel](https://gitter.im/arvados/development) or by other means.
+7. A member of the core team will review the pull request. They may have questions or comments, or request changes.
+8. When the contribution is ready, a member of the core team will
+merge the pull request into the main branch, which will
+automatically resolve the pull request.
+
+The Arvados project does not require a contributor agreement in advance, but does require each commit message include a [Developer Certificate of Origin](https://dev.arvados.org/projects/arvados/wiki/Developer_Certificate_Of_Origin). Please ensure *every git commit message* includes `Arvados-DCO-1.1-Signed-off-by`. If you have already made commits without it, fix them with `git commit --amend` or `git rebase`.
+
+The Developer Certificate of Origin line looks like this:
+
+```
+Arvados-DCO-1.1-Signed-off-by: Joe Smith <joe.smith@example.com>
+```
+
+New files must also include `SPDX-License-Identifier` at the top with one of the three Arvados open source licenses. See [COPYING](COPYING) for details.
+
+# Continuous integration
+
+Continuous integration is hosted at https://ci.arvados.org/
+
+Currently, external contributors cannot trigger builds. We are investigating integration with Github pull requests for the future.
