+Python plugin for [asdf](https://github.com/asdf-vm/asdf) version manager
+
+## Install
+
+```
+asdf plugin-add python https://github.com/tuvistavie/asdf-python.git
+```
+
+## Use
+
+Check [asdf](https://github.com/asdf-vm/asdf) readme for instructions on how to install & manage versions of Python.
+
+When installing Python using `asdf install`, you can pass custom configure options with the following env vars:
+
+* `PYTHON_CONFIGURE_OPTIONS` - use only your configure options
+* `PYTHON_EXTRA_CONFIGURE_OPTIONS` - append these configure options along with ones that this plugin already uses
