+# Contributing
+
+Logr is open to pull-requests, provided they fit within the intended scope of
+the project.  Specifically, this library aims to be VERY small and minimalist,
+with no external dependencies.
+
+## Compatibility
+
+This project intends to follow [semantic versioning](http://semver.org) and
+is very strict about compatibility.  Any proposed changes MUST follow those
+rules.
+
+## Performance
+
+As a logging library, logr must be as light-weight as possible.  Any proposed
+code change must include results of running the [benchmark](./benchmark)
+before and after the change.
