+# How to contribute
+
+You can:
+
+- Add or improve the support of an application (Check the [TODO][TODO] and
+  [TOFIX][TOFIX] tasks and pick one)
+- Improve the Mackup codebase
+- You can triage issues which may include reproducing bug reports or asking for
+  vital information, such as version numbers or reproduction instructions. If
+  you would like to start triaging issues, one easy way to get started is to
+  [subscribe to mackup on CodeTriage](https://www.codetriage.com/lra/mackup).
+  [![Open Source Helpers][CODETRIAGE-IMG]][CODETRIAGE]
+
+To speed up Pull Request (PR) approval and merger into Mackup, please follow
+these guidelines:
+
+- Keep one application supported per PR
+- Add the application to the list of supported applications in
+  [README.md][README.md]
+- Add your change to the WIP section of the [CHANGELOG.md][CHANGELOG.md]
+- Sync configurations should follow the following principles:
+  - Syncing should not break the application, and PRs should be tested
+  - Syncing should not break any syncing functionality internal to the
+    application
+  - The configuration should sync the minimal set of data, so that syncing
+    happens quickly. Leave large app data out of the sync configuration.
+  - Do not sync any file or folder that represents some state, like session
+    data, cache, any file specific to the local workstation.
+  - Do not sync sensitive information, like clear passwords or private keys
+
+Thank you for your contribution!
