+Develop
+-------
+
+
+To allow local development you either need a configuration file named
+`.botz.yaml` in the root of the project with something like this:
+
+```
+---
+base_uri: "<your_target_uri>"
+debug: true
+headless: true
+log:
+  level: DEBUG
+  syslog: false
+http:
+  bind_addr:
+    - "127.0.0.1"
+  port: 3003
+  cookie_secure: false
+  cors_allow: "http://localhost:3000"
+```
+
+Read the docstring in `api/conf.py` to understand the menaning of the
+various parameters.
+
+*Do not `pip install -e .`*. It will miss the geckodriver download step.
+Take a look at the provided `Dockerfile`.
+
+You can either run it:
+
+```
+$ docker build -t botz:latest .
+$ docker run -v $PWD:/app -p "3003:3003" botz
+```
+
+and find a working app at `http://localhost:3003`.
+Or you can `python setup.py bdist_wheel && python setup.py develop`.
+You will need:
+
+- `python >= 3.7`
+- `yarn` (`npm` support coming soon...)
+
+If you want to develop the ui, you can also serve it via yarn (as it
+supports hot reload):
+
+```
+$ cd bot.z_web
+$ yarn start
+```
+
+You will find a working ui at `localhost:3000` (but you need the last two
+lines of the previous example config file).
