 #### Install
+
+`master` branch contains the latest stable release.
+
+`develop` branch has often new features, but might also cause breaking changes. To use it, you are encouraged to join our [slack channel](https://join.slack.com/t/highfrequencybot/shared_invite/enQtMjQ5NTM0OTYzMzY3LWMxYzE3M2MxNDdjMGM3ZTYwNzFjMGIwZGRjNTc3ZGU3MGE3NzdmZGMwNmU3NDM5ZTNmM2Y3NjRiNzk4NmM4OGE).

@@ -60,18 +71,75 @@ $ cp config.json.example config.json
 $ python -m venv .env
 $ source .env/bin/activate
 $ pip install -r requirements.txt
-$ ./main.py
+$ pip install -e .
+$ ./freqtrade/main.py
 ```
 
+There is also an [article](https://www.sales4k.com/blockchain/high-frequency-trading-bot-tutorial/) about how to setup the bot (thanks [@gurghet](https://github.com/gurghet)).
+
 #### Execute tests
 
 ```
-$ python -m unittest
+$ pytest
+```
+This will by default skip the slow running backtest set. To run backtest set:
+
+```
+$ BACKTEST=true pytest -s freqtrade/tests/test_backtesting.py
 ```
 
 #### Docker
+
+Building the image:
+
 ```
 $ cd freqtrade
 $ docker build -t freqtrade .
-$ docker run --rm -it freqtrade
 ```
+
+For security reasons, your configuration file will not be included in the
+image, you will need to bind mount it. It is also advised to bind mount
+a SQLite database file (see second example) to keep it between updates.
+
+You can run a one-off container that is immediately deleted upon exiting with
+the following command (config.json must be in the current working directory):
+
+```
+$ docker run --rm -v `pwd`/config.json:/freqtrade/config.json -it freqtrade
+```
+
+To run a restartable instance in the background (feel free to place your
+configuration and database files wherever it feels comfortable on your
+filesystem):
+
+```
+$ cd ~/.freq
+$ touch tradesv2.sqlite
+$ docker run -d \
+  --name freqtrade \
+  -v ~/.freq/config.json:/freqtrade/config.json \
+  -v ~/.freq/tradesv2.sqlite:/freqtrade/tradesv2.sqlite \
+  freqtrade
+```
+If you are using `dry_run=True` you need to bind `tradesv2.dry_run.sqlite` instead of `tradesv2.sqlite`.
+
+You can then use the following commands to monitor and manage your container:
+
+```
+$ docker logs freqtrade
+$ docker logs -f freqtrade
+$ docker restart freqtrade
+$ docker stop freqtrade
+$ docker start freqtrade
+```
+
+You do not need to rebuild the image for configuration
+changes, it will suffice to edit `config.json` and restart the container.
+
+#### Contributing
+
+Feel like our bot is missing a feature? We welcome your pull requests! Few pointers for contributions:
+
+- Create your PR against the `develop` branch, not `master`.
+- New features need to contain unit tests.
+- If you are unsure, discuss the feature on [slack](https://join.slack.com/t/highfrequencybot/shared_invite/enQtMjQ5NTM0OTYzMzY3LWMxYzE3M2MxNDdjMGM3ZTYwNzFjMGIwZGRjNTc3ZGU3MGE3NzdmZGMwNmU3NDM5ZTNmM2Y3NjRiNzk4NmM4OGE) or in a [issue](https://github.com/gcarq/freqtrade/issues) before a PR.
