# Configuring the Libre Mainnet

Now we will configure the Libre Mainnet. Depending on your needs, you may want to configure the Libre Testnet as well.

## Libre Mainnet

To configure the Libre Mainnet, select “Manage Blockchains” from the blockchain selector drop down near the top of the Anchor windows:

Scroll down through the list of "Available Blockchains" until you find the option to “Add/Remove” option.  Click on “Add/Remove”.

You will be presented with a list of blockchains you can enable within Anchor Wallet. We'll need to click on "Custom Blockchain" to configure support for Libre.

Click “Save” when complete.

You will be returned to the Add/Remove Blockchain screen.  Scroll down to find the newly added custom blockchain called “Libre”:

Anchor Wallet is now configured to communicate with the Libre Mainnet.

Next we'll configure custom Mainnet tokens used within the Libre ecosystem.
