 ## Development
 
 - install `poetry` via `pipx`
-- install dependencies with `poetry install`
 - activate the virtual environment managed by poetry via `poetry shell`
+  Note that on some environments this command may cause collissions with
+  configured keyboard shortcuts.  If there are problems, you can source
+  the environment variables from the autogenerated venv with:
+  `source $(poetry env info --path)/bin/activate`
+- install dependencies into the activated environment with `poetry install`
 - run the example via `python cmd/fhttp/main.py`
 - deactivate the virtual environment with `exit`
