# flexassistant

[Flexpool.io](https://www.flexpool.io/) is a famous cryptocurrency mining or farming pool supporting
[Ethereum](https://ethereum.org/en/) and [Chia](https://www.chia.net/) blockchains. As a miner, or a farmer, we like to
get **notified** when a **block** is mined, or farmed. We also like to keep track of our **unpaid balance** and our
**transactions** to our personal wallet.

*flexassistant* is a tool that parses the Flexpool API and sends notifications via [Telegram](https://telegram.org/).

## Installation

*Note: this guide has been written with Linux x86_64 in mind.*

### Binaries

Go to [Releases](/releases) to download the binary in the version you like (latest is recommended) into a `bin` directory.

Write checksum information to a local file:

```
echo checksum > flexassistant-VERSION-Linux-x86_64.sha256sum
```

Verify checksums to avoid binary corruption:

```
sha256sum -c flexassistant-VERSION-Linux-x86_64.sha256sum
```

### Compilation

You will need to install [Go](https://golang.org/dl/), [Git](https://git-scm.com/) and a development toolkit (including [make](https://linux.die.net/man/1/make)) for your environment.

Then, you'll need to download and compile the source code:

```
git clone https://github.com/jouir/flexassistant.git
cd flexassistant
make
```

The binary will be available under the `bin` directory:

```
ls -l bin/flexassistant
```

## Configuration

*flexassistant* can be configured using a YaML file. By default, the `flexassistant.yaml` file is used but it can be another file provided by the `-config` argument.

As a good start, you can copy the configuration file example:

```
cp -p flexassistant.yaml.example flexassistant.yaml
```

Then edit this file at will.
