-A generic RAG demo
+A Sogeti Nederland generic RAG demo
+
+## Getting Started
+
+Please mind due to use of argparse the generic RAG demo can not be launched the usual way chainlit is started. 
+
+```bash
+chainlit run generic_rag/app.py  # will not work
+```
+
+Instead, the app can be launched and debugged the usual way.
+
+```bash
+python generic_rag/app.py -p data  # will work
+python generic_rag/app.py --help  # will work and prints command line options
+```
+
+
+## Chainlit starters
+
+Chainlit suggestions (starters) can be set with the `CHAINLIT_STARTERS` environment variable.
+The variable should be a JSON array of objects with `label` and `message` properties.
+An example is given below
+
+```
+
+CHAINLIT_STARTERS=[{"label":"Label 1","message":"Message one."},{"label":"Label 2","message":"Message two."},{"label":"Label 3","message":"Message three."}]
+
+```
