+# Setup and run
+
+Within `chat` directory
+
+    pyenv local 3.8
+    python -m venv venv
+    source venv/bin/activate
+    pip install -r requirements.txt
+
+Install ESpeak, see below
+
+**Set config:**
+
+In `chat` folder copy file `config-sample.json` to new file with name `config.json`  and set especially the OpenAI API Key,
+the other values can be kept as default.
+
+See section "Recording Audio" for getting correct Device ID on Raspberry. You can execute `record_audio.py` to see a list of available devices with IDs.
+
+**Run:**
+
+Execute `main.py` e.g.
+
+    python -m main
+
+# Recording Audio 
+
+## Python package PyAudio
+
+Installed via pip
