# 🌐 4. Configure Your Node

#### 🧾 Step 1: Replace the Genesis File

Delete the auto-generated genesis file and other files as well :

```bash
rm -rf  $HOME/.qieMainnetNode/config/genesis.json
rm -rf  $HOME/.qieMainnetNode/config/config.toml
rm -rf  $HOME/.qieMainnetNode/config/client.toml
rm -rf  $HOME/.qieMainnetNode/config/app.toml
```

***

#### 🧾 Step 2: Replace the Genesis File and others.

```bash
cp -r $HOME/QIEV3Mainnet/genesis.json $HOME/.qieMainnetNode/config
cp -r $HOME/QIEV3Mainnet/config.toml $HOME/.qieMainnetNode/config
cp -r $HOME/QIEV3Mainnet/client.toml $HOME/.qieMainnetNode/config
cp -r $HOME/QIEV3Mainnet/app.toml $HOME/.qieMainnetNode/config
```

Then, copy the `genesis.json` and other Necesories files from your existing Node 1 and place it here.

####  🧾 Step 3: Set a Name for Your Validator Node

To personalize and identify your validator node on the QIE Mainnet, you need to set a unique name (moniker). This name will be visible on the [QIE Validators Page](https://mainnet.qie.digital/validators).

**🔧 Edit the Configuration File**

Run the following command to open the configuration file in the terminal:

```
nano $HOME/.qieMainnetNode/config/config.toml
```

Inside the file, locate the following line :

```
moniker = "<Add_your_name>"
```

Replace `"<Add_your_name>"` with your preferred **unique** node name. This will serve as your validator identity on the network.

> 💡 **Tip:** Choose a recognizable and meaningful name, especially if you plan to become a validator.

**💾 Save and Exit**

After editing the line:

1. Press `Ctrl + X` to exit.
2. Press `Y` to confirm saving the changes.
3. Hit `Enter` to finalize and close the file.

Your node name has now been successfully updated!
