```

## ***Manual Installation***

```bash
# Come up with the name of your node and replace it instead <your_moniker>
MONIKER=<your_moniker>
```

```bash
# Download binary files
cd $HOME 
rm -rf celestia-app 
git clone https://github.com/celestiaorg/celestia-app.git 
cd celestia-app 
git checkout v6.4.10

make install
```

```bash
# Config and initialize the node
celestia-appd config set client chain-id celestia
celestia-appd config set client keyring-backend file
celestia-appd config set client node tcp://localhost:26657

celestia-appd init $MONIKER --chain-id celestia
```

```bash
# Download genesis and addrbook
wget -O $HOME/.celestia-app/config/genesis.json https://mainnets1.validexis.com/celestia/genesis.json

#"catching_up": false means that the node is synchronized, we are waiting for complete synchronization
```

***Wallets***

```bash
# Create wallet
celestia-appd keys add wallet
```

The wallet has been created. In the last line there will be a phrase that must be written down

```bash
# If the wallet was already there, restore it
celestia-appd add wallet --recover

# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data
```

***Validator***

Do not forget to create a profile on <https://keybase.io/> and set a profile photo there that will be imported by key and used for your validators.

```bash
celestia-appd tx staking create-validator \
--amount 1000000utia \
--pubkey $(celestia-appd tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id celestia \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.05 \
