-Elipticoin Blacksmith Node
+Ellipticoin Blacksmith Node
 ==========
 
-Elipticoin is a Ethereum-like blockchain that's optimized for sustainability and
-developer happiness. [Stakers](https://en.wikipedia.org/wiki/Proof-of-stake) run
-blacksmith nodes to form consensus on transactions on the network in return for
-staking rewards. This is the reference implementation of a
-blacksmith node written in Elixir and Rust.
+Ellipticoin is a developer friendly scalable Ethereum side-chain. Blacksmith
+nodes forge transactions to keep the network secure. They are authenticated via [proof
+of
+burn](https://www.masonforest.com/blockchain/ethereum/ellipticoin/2018/05/29/the-ellipticoin-proof-of-burn-algorithm.html)
+which has similar economic incentives to proof of work except instead of
+burning energy they burn tokens on the parent chain.
 
-You can access the Elipticoin network using the [reference wallet](https://www.npmjs.com/package/ec-wallet).
+You can install the [reference wallet](https://www.npmjs.com/package/ec-wallet) to use the Ellipticoin network itself.
+
+
+Running a Blacksmith Node:
+==========================
+
+Using docker-compose
+-----
+1. Clone the repo:  `git clone https://github.com/ellipticoin/ellipticoin-blacksmith-node && cd ellipticoin-blacksmith-node`
+2. Install Docker
+2. Update `ETHEREUM_PRIVATE_KEY` in `config/docker.env`
+3. Run `docker-compose up`
+
+From a binary release
+-----
+
+1. Create an `Ubuntu 18.04` VPS/Droplet (or another type of VPS and create a
+   PR!)
+2. Download the appropriate release for your system and extract it:
+````
+$ cd /usr/local
+$ wget blacksmith.tar.gz
+$ tar -xf blacksmith.tar.gz
+$ rm blacksmith.tar.gz
+````
+3. Run `sh ./releases/0.1.0/commands/install_deps.sh` to install the required dependencies.
+4. Allow all postgres connections from localhost:
+
+Edit: /etc/postgresql/10/main/pg_hba.conf
+
+    Change the line:
+````
+local   all             postgres                                peer
+````
+to
+````
+local   all             postgres                                trust
+````
+5. Restart postgres: `sudo service postgresql restart`
+
+6. Create the blacksmith's db: `createdb -U postgres blacksmith`
+7. Update `ETHEREUM_PRIVATE_KEY` and anything else you'd like to customize in
+   `/usr/local/etc/config.exs`
+
+9. Run the blacksmith node in the forground to check if everything is set up correctly: `blacksmith foreground`
+
+10. If everything looks to be working you can kill the node and start it again in the background: `blacksmith start`
+
+From Source
+-----
+1. Clone the repo:  `git clone https://github.com/ellipticoin/ellipticoin-blacksmith-node && cd ellipticoin-blacksmith-node`
+2. Update `ETHEREUM_PRIVATE_KEY` and anything else you'd like to customize in
+   `config/dev.secret.exs` and `config/dev.exs`
+3. Run: `mix dep.get`
+4. Run: `mix run --no-halt`
