+This is a custom Docker image for [bitwarden_rs](https://github.com/dani-garcia/bitwarden_rs). Bitwarden_rs is a Bitwarden server API implementation written in Rust compatible with upstream Bitwarden clients, perfect for self-hosted deployment where running the official resource-heavy service might not be ideal.
+
+> **WARNING**: While bitwarden_rs does not allow to compile binaries with multi DB providers, this build will only work with a PostgreSQL database backend.
