There are probably guides but I don't know one off hand. You need:

1. A lightning wallet that supports LNURL or LN address, and optionally NIP-57 (zaps). Options: Wallet of Satoshi, Alby, ln.tips, possibly others

2. A nostr client that supports NIP-57 (zaps). Different clients have different options: fixed amount, custom amounts, etc.

Looks like you already have WoS. For clients there are lots of options now too, but if the one you're using doesn't have the options you want, just try another one. Amethyst, Damus, nostrgram, snort are probably the best options at the moment.
