+# flexpool-activity
+
+[Flexpool.io](https://flexpool.io) is a next-generation [Ethereum](https://ethereum.org/en/) mining pool known for their
+[#STOPEIP1559](https://stopeip1559.org/) move. `flexpool-activity` is able to listen and notify when a new **block** is
+mined by the pool and display the up-to-date **miner balance** and convert it to **fiat**.
+
+## Installation
+
+```
+sudo apt install python3-virtualenv
+virtualenv venv
+source venv/bin/activate
+pip install -r requirements.txt
+```
+
+## Telegram bot
+
+This [tutorial](https://takersplace.de/2019/12/19/telegram-notifications-with-nagios/) explains how to create a Telegram
+bot. You'll need the `chat_id` and `auth_key` for the next section.
+
+## Configuration
+
+Configuration file use the JSON format with the following keys:
+* `miner`: wallet address of the miner
+* `currency`: symbol of the currency to convert (default: USD)
+* `telegram`: send notifications with Telegram (optional)
+    * `auth_key`: Telegram authentication key for the bot API
+    * `chat_id`: Telegram chat room id (where to send the message)
+* `state_file`: persist data between runs into this file (default: `state.json`)
+
+See [configuration example](config.example.json).
+
+
+## Usage
+
+```
+python3 main --help
+```
+
+
+## Contribute
+
+Contributions are welcomed! Feel free to update the code and create a pull-request.
+
+Be sure to lint the code before:
+
+```
+docker build -t pre-commit .
+docker run -it -v $(pwd):/mnt/ --rm pre-commit bash
+# cd /mnt/
+# pre-commit run --all-files
+# exit
+```
