+## Deployment
+
+The deployment uses [ocurrent-deployer][] to watch particular branches on this repository, plus the default branches of [opam-repository][] and [platform-blog][]. 
+When any of them change, it calculates if it needs to rebuild the docker image. A site rebuild is therefore triggered by any merge to opam-repository.
+
+ * `live` branch is deployed on [opam.ocaml.org][]
+ * `staging` branch is deployed on [staging.opam.ocaml.org][]
+
+The deployer service is available at https://deploy.ci.ocaml.org/?repo=ocaml-opam/opam2web and the code for the ocurrent pipeline is in [ocurrent-deployer]().
