 # Open Media Match
-Open Media Match has moved! It's now in the hasher-matcher-actioner directory.
+Open Media Match has moved! It's merged with Hasher Matcher Actioner and now lives in the [hasher-matcher-actioner](https://github.com/facebook/ThreatExchange/tree/main/hasher-matcher-actioner) directory.
+
+## Existing devcontainers
+If you had a devcontainer pointed at this directory, it will fail on startup. You'll need to rebuild it in the new directory, the same as if you were a new user. Follow the devcontainer instructions in [hasher-matcher-actioner/CONTRIBUTING.md](https://github.com/facebook/ThreatExchange/blob/main/hasher-matcher-actioner/CONTRIBUTING.md) to get up and running again!
