 shellcompletion scripts for supported shells (bash, fish, zsh, powershell). This
 command is also the entry point for running the completion logic and can be used to
 debug completer code.
+
+It invokes typer's shell completion installation logic, but does have to patch the
+installed scripts. This is because there is only one installation for all django
+management commands, not each individual command. The completion logic here will
+failover to django's builtin autocomplete if the command in question is not a 
+TyperCommand. To promote compatibility with other management command libraries or
+custom completion logic, a fallback completion function can also be specified. A
+needed refactoring here would be to provide root hooks for completion logic in django
+that base classes can register for. This would provide a coordinated way for libraries
+like django-typer to plug in their own completion logic.
