 ### Debugpy
 
-You need to install `debugpy` using either your package manager or via `pip`.
-For example:
+Options to install [debugpy][3]:
+
+1. Via a system package manager. For example:
 
 ```bash
-mkdir .virtualenvs
-cd .virtualenvs
+pacman -S python-debugpy
+```
+
+2. Via `pip` in a `venv`:
+
+```bash
+mkdir ~/.virtualenvs
+cd ~/.virtualenvs
 python -m venv debugpy
 debugpy/bin/python -m pip install debugpy
 ```
 
-If you're using virtual environments for your project it will automatically get
-picked up if it is active before `nvim` starts, or if it is in a default
-location. See [Python dependencies and
+Note that the virutalenv used for the `debugpy` can be independent from any
+virtualenv you're using in your projects.
+
+`nvim-dap-python` tries to detect your project `venv` and should recognize any
+dependencies your project has. See [Python dependencies and
 virtualenv](#python-dependencies-and-virtualenv)

+3. Implicit via [uv][uv]
+
+See [Usage](#Usage): You need to use `require("dap-python").setup("uv")`
