## Installation guide

Make sure you have the latest Go build and system components installed

Download the source files:

```
wget https://github.com/ignite/cli/releases/download/v0.27.1/ignite_0.27.1_linux_amd64.tar.gz
```

Modify file permissions:

```
chmod +x ignite_0.27.1_linux_amd64.tar.gz
```

Extract the TAR file:

```
tar -xvf ignite_0.27.1_linux_amd64.tar.gz
```

Move the binary:

```
sudo mv ignite /usr/local/bin
```

Verify installation:

```
ignite version
```

Set up environment variables:

```
export PATH=$PATH:/usr/local/go/bin
```

## Running a Full Node

Download binary

```
wget https://github.com/airchains-network/junction/releases/download/v0.1.0/junctiond
```

Make the binary executable

```
chmod +x junctiond
```

Move the binary to a system-wide directory

```
sudo mv junctiond /usr/local/bin
```

Initialize the Node with the Moniker

```
junctiond init <moniker>
```

Update Genesis Configuration

```
wget https://github.com/airchains-network/junction/releases/download/v0.1.0/genesis.json
```

Replace the Existing Genesis File

- Start
sudo systemctl start junctiond

- Stop
sudo systemctl stop junctiond

- Restart
sudo systemctl restart junctiond

- Check Status
sudo systemctl status junctiond

```
junctiond keys add wallet --recover
```

List All Keys

```
junctiond keys list
```

Query Wallet Balance

```
junctiond q bank balances $(junctiond keys show wallet -a)
```

To obtain the pubkey:

```
junctiond comet show-validator
```

## Creat file Validator.json ( nano validator.json )

```

Finally, create the validator:

```
junctiond tx staking create-validator path/to/validator.json --from wallet --chain-id junction --fees 500amf
```

## Set max peer

```
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.junction/config/config.toml
