+1. Deactivate any env, and [install `pipx`](https://pipx.pypa.io/stable/installation/)
+
+- Linux
+
+```bash
+sudo apt update
+sudo apt install pipx
+pipx ensurepath
+```
+
+- MacOS
+
+```bash
+brew install pipx
+pipx ensurepath
+```
+
+2. Install `poetry`
+
+There are other managers like `uv`, or just plain `pip` but `pip` alone does not nicely manage the versions in the `pyproject.toml`.
+
+```bash
+pipx install poetry
+pipx upgrade poetry
+# pipx uninstall poetry
+```
+
+Tab completions:
+
+```bash
+poetry completions bash >> ~/.bash_completion
+```
+
+You can add an alias `alias sve=source .venv/bin/activate/`; then open or re-open a terminal and do, in your project folder:
+
+```bash
+python3.11 -m venv .venv
+sve
+```
+
+and should be it.
