+# Butter Robot
+
+[![Docker Repository on Quay](https://quay.io/repository/fmartingr/butterrobot/status "Docker Repository on Quay")](https://quay.io/repository/fmartingr/butterrobot)
+
+Python framework to create bots for several platforms.
+
+![Butter Robot](./assets/icon@120.png)
+
+> What is my purpose?
+
+## Supported platforms
+
+| Name            | Receive messages | Send messages |
+| --------------- | ---------------- | ------------- |
+| Slack (app)     | Yes              | Yes           |
+| Slack (webhook) | Planned          | No[^1]            |
+| Telegram        | Yes              | Yes           |
+
+[^1]: Slack webhooks only supports answering to incoming event, not
+      sending messages on demand.
+
+## Provided plugins
+
+### Butter robot
+
+- [ ] Help
+- [ ] Usage
+- [ ] Changelog
+
+### Development
+
+- [x] Ping
+
+### Fun and entertainment
+
+- [ ] Dice roll
+- [x] Loquito
+
+## Installation
+
+### PyPi
+
+You can run it directly by installing the package and calling it
+with `python` though this is not recommended and only intended for
+development purposes.
+
+```
+$ pip install --user butterrobot
+$ python -m butterrobot
+```
+
+### Containers
+
+The `fmartingr/butterrobot` container image is published on quay.io to
+use with your favourite tool:
+
+```
+podman run -d --name butterrobot -p 8080:8080 quay.io/fmartingr/butterrobot
+```
+
+## Contributing
+
+To run the project locally you will need [poetry](https://python-poetry.org/).
+
+```
+git clone git@github.com:fmartingr/butterrobot.git
+cd butterrobot
+poetry install
+```
+
+Create a `.env-local` file with the required environment variables,
+you have [an example file](.env-example).
+
+```
+SLACK_TOKEN=xxx
+TELEGRAM_TOKEN=xxx
+...
+```
+
+And then you can run it directly with poetry
+
+TODO: Autoload .env-local
+
+```
+docker run -it --rm --env-file .env-local -p 5000:5000 -v $PWD/butterrobot:/etc/app/butterrobot local/butterrobot python -m butterrobot
+```
