`Witness Essentials: Pricefeed` received an update, which includes:

- Docker Support (incl. PM2 for 24/7 uptime)
- USDT > USD Calculation (USDT Peg is broken)
- Few smaller changes (Private Active-key is now saved inside the config.json instead of .env, better logging, etc.)

<h2>What is Witness Essentials?</h2>

`Witness Essentials` is a collection of important tools for witnesses.

If you're interested in working with me on them, let me know so I can invite you into the organization.

<h2>Pricefeed Overview</h2>

The goal for this script was to bring another great alternative to the landscape of witness-tools. @someguy123 & @drakos are providing two other great scripts. But for decentralisation, it's better to have more alternatives, than not enough.

Here are a few of the key features:

- 5 major exchanges supported
- Transaction signing either via private signing-key or private active-key
- RPC Failover
- USDT > USD calculation (can be disabled in the config)
- PEG support
- Robust error handling.

---

<h2>Getting Started</h2>

The easiest way to get started is to use Docker:

```
git clone https://github.com/witness-essentials/pricefeed.git
cd pricefeed
chmod +x run.sh
./run.sh install_docker
./run.sh build
./run.sh start
```

For more detailed installation instructions (incl. manually with node) check out the repository:

<h2>Update Instructions</h2>

If you're upgrading from an old version, make sure to edit the config accordingly.

The `.env`-file has been removed and the private active-key has to be added to the config now. But only if you're not using the private signing-key feature AND/OR if the witness is disabled and you want to still publish the feed.

---

<h2>For Utopian</h2>

I initially re-worked and published the new price feed in the aftermath of HF20 and due to the voting mana drainage, I didn't add it to utopian-io.

If the previous world could be considered in the review of this contribution, that would be great!
