 Since `~/.env_goodies` is a cloned repository, pulling new changes should update everything. You may need to `source`
 the shell configuration file again for new goodies to apply.
+
+## Structure
+
+The package is structured as such:
+
+```
+env/
+    setup # Adds bootstrap block to your shell's config file.
+    source/
+        ... # Anything here is sourced on shell-start
+```
+
+Adding files to `source/` will add code that gets executed on shell-start. Files are discovered by globbing in the
+bootstrap block added by `setup` and do not need to be registered anywhere.
