# Joining a Testnet This document outlines the steps to join an existing testnet ## Steps 1. Install the Ethermint binary ethermintd ```bash go install https://github.com/tharsis/ethermint ``` 2. Create an Ethermint account ```bash ethermintd keys add ``` 3. Copy genesis file Follow this [link](https://gist.github.com/araskachoi/43f86f3edff23729b817e8b0bb86295a) and copy it over to the directory ~/.ethermintd/config/genesis.json 4. Add peers Edit the file located in ~/.ethermintd/config/config.toml and edit line 350 (persistent_peers) to the following ```toml "05aa6587f07a0c6a9a8213f0138c4a76d476418a@18.204.206.179:26656,13d4a1c16d1f427988b7c499b6d150726aaf3aa0@3.86.104.251:26656,a00db749fa51e485c8376276d29d599258052f3e@54.210.246.165:26656" ``` 5.
