+-- ft.page: FPM Controller Support
+
+FPM cli supports communication with [fpm
+controller](https://github.com/FifthTry/fpm-controller). This is an optional
+feature, and is only available when `controller` feature is enabled, which is
+not enabled by default.
+
+-- ft.h1: Controller Communication
+
+When `controller` feature is enabled, `fpm serve` will first communicate with
+the FPM controller service's `/get-package/` API.
+
+-- ft.h2: FPM Controller Service Endpoint
+
+The FPM Controller Service's enpoint is computed by using environement
+variable `FPM_CONTROLLER`, which will look something like this:
+`https://controller.fifthtry.com`, with the API path.
+
+FPM Controller Service has more than one APIs: /get-package/ and /fpm-ready/.
+
+-- ft.h1: `/get-package/`
+
+Through an environemnt variable `FPM_INSTANCE_ID`, the `fpm serve` will learn
+it's `instance id`, and it will pass the instance id to the `get-package` API.
+
+The API returns the URL of the package to be downloaded, git repository URL and 
+the package name.
+
+FPM will clone the git repository in the current directory. The current
+directory will contain `FPM.ftd` and other files of the package.
+
+FPM will then calls [`fpm install`](/cli/install/) on it.
+
+-- ft.h1: `/fpm-ready/`
+
+Once dependencies are ready `fpm` calls `/fpm-ready/` API on the controller. We
+will pass the `FPM_INSTANCE_ID` and the git commit hash as input to the API
+
+The API will return with success, and once it is done fpm will start receiving HTTP
+traffic from the controller service.

 `fpm sync` operates in two modes. If the package is hosted on `fpm-repo` then it
 syncs the content of local folder with remote [not yet implemented]. If the package
 is hosted on `github` etc, then `sync` creates a snapshot of modified files in
