 ### 📌 Note
 RLN membership is your access key to The Waku Network. It is registered on-chain, enabling your nwaku node to send messages in a decentralized and privacy-preserving way while adhering to rate limits. Messages exceeding the rate limit will not be relayed by other peers.
 
-If you’re upgrading from a version earlier than v0.36.0, we recommend starting from a fresh clone.
-
-docker-compose automatically reads the .env file from the filesystem. A .env.example is provided as a template — copy it and update the values as needed:
-
-```
-cp .env.example .env
-${EDITOR} .env
-```
-
-Make sure to **NOT** place any secrets into `.env.example`, as they might be unintentionally published in the Git repository.
-
-if you just want to relay traffic (not publish), you don't need to perform the registration.
