# Step 3: Configure and start Stader services

### To configure Stader services, follow these steps:

1. Open the file **`~/.stader/user-settings.yml`** using a text editor of your choice.
2. Add the following information:
   * External beacon chain URL
   * External execution chain URL
   * URL of your Web3Signer with the loaded Validator Keys intended for registration with Stader.

     These URLs are primarily used for querying blockchain data and sending transactions. For the best experience, it is recommended to use the fastest available RPC endpoint.

3. Update the network to mainnet or testnet

   Under the stadernode > network section please update the network

   For Testnet- `network: prater`\
   For Mainnet - `network: mainnet`

**Note:** If you're using a self-signed CA for your Web3Signer, set the **`allowAnyCa`** parameter to true under the **`externalWeb3Signer`** section in the **`user-settings.yml`** file to skip CA verification.

### To start Stader services run the following command&#x20;

**`~/bin/stader-permissioned-cli service start`**
