+## Reporting Bugs
+
+Please file bugs in the [Github Issue
+Tracker](https://github.com/syncthing/protocol/issues).
+
+## Contributing Code
+
+Every contribution is welcome. Following the points below will make this
+a smoother process.
+
+Individuals making significant and valuable contributions are given
+commit-access to the project. If you make a significant contribution and
+are not considered for commit-access, please contact any of the
+Syncthing core team members.
+
+All nontrivial contributions should go through the pull request
+mechanism for internal review. Determining what is "nontrivial" is left
+at the discretion of the contributor.
+
+### Authorship
+
+All code authors are listed in the AUTHORS file. Commits must be made
+with the same name and email as listed in the AUTHORS file. To
+accomplish this, ensure that your git configuration is set correctly
+prior to making your first commit;
+
+    $ git config --global user.name "Jane Doe"
+    $ git config --global user.email janedoe@example.com
+
+You must be reachable on the given email address. If you do not wish to
+use your real name for whatever reason, using a nickname or pseudonym is
+perfectly acceptable.
+
+## Coding Style
+
+- Follow the conventions laid out in [Effective Go](https://golang.org/doc/effective_go.html)
+  as much as makes sense.
+
+- All text files use Unix line endings.
+
+- Each commit should be `go fmt` clean.
+
+- The commit message subject should be a single short sentence
+  describing the change, starting with a capital letter.
+
+- Commits that resolve an existing issue must include the issue number
+  as `(fixes #123)` at the end of the commit message subject.
+
+- Imports are grouped per `goimports` standard; that is, standard
+  library first, then third party libraries after a blank line.
+
+- A contribution solving a single issue or introducing a single new
+  feature should probably be a single commit based on the current
+  `master` branch. You may be asked to "rebase" or "squash" your pull
+  request to make sure this is the case, especially if there have been
+  amendments during review.
+
+## Licensing
+
+All contributions are made under the same MIT license as the rest of the
+project, except documentation, user interface text and translation
+strings which are licensed under the Creative Commons Attribution 4.0
+International License. You retain the copyright to code you have
+written.
+
+When accepting your first contribution, the maintainer of the project
+will ensure that you are added to the AUTHORS file. You are welcome to
+add yourself as a separate commit in your first pull request.
+
+## Tests
+
+Yes please!
+
+## License

-Docker Build
-============
-
-Official builds are produced using a Docker image specified by the
-Dockerfile in this directory. The following commands exactly reproduce
-the official build process.
-
-Create an image called `syncthing/build` with the build environment.
-
-```
-./build.sh docker-init
-```
-
-> This is a Debian based image containing the latest stable version of
-> Go set up for cross compilation. The cross compilation uses the
-> dynamically linked standard libraries and SSE instructions for amd64
-> builds, but static linking and minimal instruction set for the 386 and
-> arm builds. The command should be run in the main repo directory, as a
-> user with permission to perform Docker operations.
-
-Build the full set of supported binaries.
-
-```
-./build.sh docker-all
-```
-
-> This uses a temporary container with the image from above and a volume
-> mapped to the directory containing the source. Tests are run and
-> binary packages created.
