+# bash
+
+Forked version of bash supporting shell interactions (e.g. writing builtins or
+modifying variables, arrays, and functions) natively in rust via the scallop crate.
+
+## Development
+
+Note that the development workflow involves rebasing against upstream and force
+pushing to keep the patch stack in order.
