+# Indexer
+
+Catches events, stores them in the database to be queried via API.
+
+## Running the app
+
+run `cp .default.env .env`, and add your own private key as `RELAYER_ECDSA_KEY` in `.env`. You need to be running a MySQL instance, and replace all the `MYSQL_` env vars with yours.
+
+Run `go run cmd/main.go --help` to see a list of possible configuration flags, or `go run cmd/main.go` to run with defaults, which will process messages from L1 to L2, and from L2 to L1, and start indexing blocks from 0.
