The plugin consist of 2 elements:
1. NFTs
2. Candy Machine
Depending on the features you need, add the one that has these features on the page and then see the demo editor on how to use them.
Insert an RPC URL in the plugin element field called "RPC Node Endpoint"
You can use a public RPC that can be found here:
https://docs.solana.com/cluster/rpc-endpointsBut we recommend using a private RPC since the public one is often congested.
Note!
Make sure to have at least 1 Sol in your wallet to avoid errors that comes from the SDK when the balance is too low.
Testnet for the minting currently isn't working, it is expected to be fixed with newer version of the SDK.
