```

**Install GO**&#x20;

```
cd $HOME ver="1.21.1" wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" sudo rm -rf /usr/local/go sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" rm "go$ver.linux-amd64.tar.gz" echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile source $HOME/.bash_profile go version
```

```
cd $HOME
git clone https://github.com/celestiaorg/celestia-app.git
cd celestia-app
git checkout tags/v1.11.0 -b v1.11.0
make install
cd celestia-app
```

```
celestia-appd init "your node" --chain-id mocha
celestia-appd config chain-id mocha
celestia-appd config keyring-backend test
```

## Copy genesis - Minimum gas prices - Addrbook

```
cp $HOME/networks/mocha-4/genesis.json $HOME/.celestia-app/config/
```

```
sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0.002utia\"|" $HOME/.celestia-app/config/app.toml

curl -Ls https://snapshots.kjnodes.com/celestia-testnet/addrbook.json > $HOME/.celestia-app/config/addrbook.json
