+## Provide an virtual environment for python engine
+
+Benefit: having a separate virtual environment for your editor than the one
+your working into.
+
+Install `pyenv` with the [`pyenv-installer`][9].
+
+Install the python version you need with `pyenv`:
+
+```bash
+pyenv install 3.9.9
+```
+
+Create and name the virtual environment for neovim:
+
+```bash
+pyenv virtualenv 3.9.9 neovim
+```
+
+Activate the virtual environment and fetch the python path:
+
+```bash
+pyenv activate neovim
+pyenv which python      #Note the provided path
+```
+
+Add the following line to your `init.vim`:
+
+```init.vim
+let g:python3_host_prog = '/full/path/to/neovim/bin/python
+```
+
+Install the python dependencies in the virtual environment as it is activated:
+
+```bash
+pip install neovim pynvim …
+```
+
+To deactivate the virtual environment:
+
+```bash
+pyenv deactivate
+```
