 ## Contributing Documentation
 
 Updates to the [documentation site](https://docs.syncthing.net/) can be
 made as pull requests on the [documentation
 repository](https://github.com/syncthing/docs).
 
+## Contributing Code
+
+Every contribution is welcome. If you want to contribute but are unsure
+where to start, any open issues are fair game! Here's a short rundown of
+what you need to keep in mind:
+
+- Don't worry. You are not expected to get everything right on the first
+  attempt, we'll guide you through it.
+
+- Make sure there is an
+  [issue](https://github.com/syncthing/syncthing/issues) that describes the
+  change you want to do. If the thing you want to do does not have an issue
+  yet, please file one before starting work on it.
+
+- Fork the repository and make your changes in a new branch. Once it's ready
+  for review, create a pull request.
+
+### Authorship
+
+All code authors are listed in the AUTHORS file. When your first pull
+request is accepted your details are added to the AUTHORS file and the list
+of authors in the GUI. 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.
+
+### The Developer Certificate of Origin (DCO)
+
+The Syncthing project requires the Developer Certificate of Origin (DCO)
+sign-off on pull requests (PRs). This means that all commit messages must
+contain a signature line to indicate that the developer accepts the DCO.
+
+The DCO is a lightweight way for contributors to certify that they wrote (or
+otherwise have the right to submit) the code and changes they are
+contributing to the project. Here is the full [text of the
+DCO](https://developercertificate.org):
+
+---
+
+By making a contribution to this project, I certify that:
+
+1. 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
+
+2. 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
+
+3. The contribution was provided directly to me by some other person who
+   certified (1), (2) or (3) and I have not modified it.
+
+4. 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.
+
+---
+
+Contributors indicate that they adhere to these requirements by adding
+a `Signed-off-by` line to their commit messages.  For example:
+
+    This is my commit message
+
+    Signed-off-by: Random J Developer <random@developer.example.org>
+
+The name and email address in this line must match those of the committing
+author, and be the same as what you want in the AUTHORS file as per above.
+
+### Coding Style
+
+#### General
+
+- All text files use Unix line endings. The git settings already present in
+  the repository attempt to enforce this.
+
+- When making changes, follow the brace and parenthesis style of the
+  surrounding code.
+
+#### Go Specific
+
+- Follow the conventions laid out in [Effective
+  Go](https://go.dev/doc/effective_go) as much as makes sense. The review
+  guidelines in [Go Code Review
+  Comments](https://github.com/golang/go/wiki/CodeReviewComments) should
+  generally be followed.
+
+- Each commit should be `go fmt` clean.
+
+- Imports are grouped per `goimports` standard; that is, standard
+  library first, then third party libraries after a blank line.
+
+### Commits
+
+- Commit messages (and pull request titles) should follow the [conventional
+  commits](https://www.conventionalcommits.org/en/v1.0.0/) specification and
+  be in lower case.
+
+- We use a scope description in the commit message subject. This is the
+  component of Syncthing that the commit affects. For example, `gui`,
+  `protocol`, `scanner`, `upnp`, etc -- typically, the part after
+  `internal/`, `lib/` or `cmd/` in the package path. If the commit doesn't
+  affect a specific component, such as for changes to the build system or
+  documentation, the scope should be omitted. The same goes for changes that
+  affect many components which would be cumbersome to list.
+
+- Commits that resolve an existing issue must include the issue number
+  as `(fixes #123)` at the end of the commit message subject. A correctly
+  formatted commit message subject looks like this:
+
+      feat(dialer): add env var to disable proxy fallback (fixes #3006)
+
+- If the commit message subject doesn't say it all, one or more paragraphs of
+  describing text should be added to the commit message. This should explain
+  why the change is made and what it accomplishes.
+
+- When drafting a pull request, please feel free to add commits with
+  corrections and merge from `main` when necessary. This provides a clear time
+  line with changes and simplifies review. Do not, in general, rebase your
+  commits, as this makes review harder.
+
+- Pull requests are merged to `main` using squash merge. The "stream of
+  consciousness" set of commits described in the previous point will be reduced
+  to a single commit at merge time. The pull request title and description will
+  be used as the commit message.
+
+### Tests
+
+Yes please, do add tests when adding features or fixing bugs. Also, when a
+pull request is filed a number of automatic tests are run on the code. This
+includes:
+
+- That the code actually builds and the test suite passes.
+
+- That the code is correctly formatted (`go fmt`).
+
+- That the commits are based on a reasonably recent `main`.
+
+- That the output from `go lint` and `go vet` is clean. (This checks for a
+  number of potential problems the compiler doesn't catch.)

+## Discovery
+
+Please note that Docker's default network mode prevents local IP addresses
+from being discovered, as Syncthing can only see the internal IP address of
+the container on the `172.17.0.0/16` subnet. This would likely break the ability
+for nodes to establish LAN connections properly, resulting in poor transfer
+rates unless local device addresses are configured manually.
+
+It is therefore strongly recommended to stick to the [host network mode](https://docs.docker.com/network/host/),
+as shown above.
+
 Be aware that syncthing alone is now in control of what interfaces and ports it
 listens on. You can edit the syncthing configuration to change the defaults if
 there are conflicts.
 
 ## GUI Security
 
-By default Syncthing inside the Docker image listens on 0.0.0.0:8384 to
-allow GUI connections via the Docker proxy. This is set by the
-`STGUIADDRESS` environment variable in the Dockerfile, as it differs from
-what Syncthing would otherwise use by default. This means you should set up
-authentication in the GUI, like for any other externally reachable Syncthing
-instance. If you do not require the GUI, or you use host networking, you can
-unset the `STGUIADDRESS` variable to have Syncthing fall back to listening
-on 127.0.0.1:
-
-```
-$ docker pull syncthing/syncthing
-$ docker run -e STGUIADDRESS= \
-    -v /wherever/st-sync:/var/syncthing \
-    syncthing/syncthing:latest
-```
-
-With the environment variable unset Syncthing will follow what is set in the
-configuration file / GUI settings dialog.
+By default Syncthing inside the Docker image listens on `0.0.0.0:8384`. This
+allows GUI connections when running without host network mode. The example
+above unsets the `STGUIADDRESS` environment variable to have Syncthing fall
+back to listening on what has been configured in the configuration file or the
+GUI settings dialog. By default this is the localhost IP address `127.0.0.1`.
+If you configure your GUI to be externally reachable, make sure you set up
+authentication and enable TLS.
