 # Brevis + EigenLayer
 ## Run as an Operator
-1. The `brevis` binary and `brevis.toml` are required to run as an operator. The `brevis` binary should be run under Linux AMD64 system. It can also be built from source with command: go build -o brevis.

 2. Make sure the total stake > 32 eth in Eigen Layer, we support same strategies as Eigen DA
 3. Add bls and ecdsa key of Eigenlayer info to the `brevis.toml` config file, both are required to join Brevis. Also recommend to change ethereum gateway RPC in the config file to a private one
 4. Run `brevis join --chainid 1 --quorums 0x01` cmd to opt-in Brevis AVS
 5. Add operator id printed by last `brevis join` command (bytes32 hex string) to config file, note it's NOT your ETH addr
 6. (optional but recommended): Remove ecdsa key info from config file as it's not needed for normal operation. only bls key is needed
 7. Operator runs `brevis run` cmd which monitors Brevis contract for new requests, and signs w/ BLS key, then posts to Brevis gateway
 
+Suggested hardware configuration: AWS C5/C6 2x large equivalent, 500GB disk, no open ports.
