+## Install
+
+### Client & CI
+
+Flux releaser is a rust app used client side and in CI as a cli app (flux-releaser), or alternatively as a rust library.
+
+### Registry
+
+Flux releaser requires a server to function. Said flux is packaged in a helm chart, and is available at `tbd`, if the helm chart is used, it will stand-up a cockroach cluster and minio for artifacts.
+
+Flux releaser also requires a connection to a flux gitops registry. This is provided to the flux app on the server via. a toml file (see configuration), but the defaults should work fine.
