+This is a Go based repository buliding a command line tool that converts the status of a git working tree for a specific directory into a tmux status string the end user can add to their tmux status line. It is designed to be used with the `tmux` terminal multiplexer.
+
+## Code Standards
+
+### Required Before Each Commit
+
+- Run `go test ./...` before committing any changes to ensure tests pass
+- Go code should be formatted with `gofmt`
+
+## Repository Structure
+
+- `./`: repository root, main package, default configuration file, and main entry point
+- `tmux/`: tmux formatting
+- `json/`: used by gitmux -dbg to print the git working tree status as a json object, for debugging purposes
+- `testdata/`: testscripts fixtures when actual gitmux output is checked against some specific conditions.
+
+## Key Guidelines
+
+1. Follow Go best practices and idiomatic patterns
+2. Maintain existing code structure and organization
+3. Write unit tests for new functionality. Use table-driven unit tests when possible.
+4. Document public options
+5. Keep table aligned in the README.md file, for a nice experience even when reading the file in a terminal

+_How does this Pull Request address the problem?_
 
-Thank you!
+## Testing
+
+ - There should be some unit tests for every behaviour change or new feature
+ - If you're adding a new configuration option, the default configuration file
+   (.gitmux.yml) should be modified with the new option
+ - There's a test that verifies that gitmux output always remains the same
+   across versions when using the default configuration. You can run it with:
+  `go test -run TestScriptst`
+ - `README.md` should always be updated.
