+## Install from source
+
+We recommend to use the [`hatch`](https://hatch.pypa.io/latest/) environment manager to install `qadence` from source:
+
+```bash
+python -m pip install hatch
+
+# get into a shell with all the dependencies
+python -m hatch shell
+
+# run a command within the virtual environment with all the dependencies
+python -m hatch run python my_script.py
+```
+
+!!! warning
+    `hatch` will not combine nicely with other environment managers such Conda. If you want to use Conda,
+    install it from source using `pip`:
+
+    ```bash
+    # within the Conda environment
+    python -m pip install -e .
