 <Note>
-  We recommend using [Pipenv](https://pipenv.pypa.io/en/latest/) for dependency
-  management and virtual environments. It's included it in our python templates
-  by default. Installation instructions:

+  We use `uv` by default in our base py-starter template. If you would prefer to use another dependency manager we also have a template for `pipenv`.
+
+If there are other dependency managers you would like to see supported, please let us know in out [github issues](github.com/nitrictech/nitric/issues).
