 * A password to protect your rln membership.
 
+There is `.env.example` available for you as a template to use for providing the above values. The process when working with `.env` files is to copy the `.env.example`, store it as `.env` and edit the values there.

 **🔑 1. Register RLN membership**
 
 The RLN membership is your access key to The Waku Network. Its registration is done onchain, and allows your go-waku node to publish messages in a decentralized and private way, respecting some [rate limits](https://rfc.vac.dev/spec/64/#rate-limit-exceeded).
