 An access-watcher serves Watch RPCs that stream changes from a relation tuple [changelog](https://authorizer-tech.github.io/docs/overview/architecture#changelog) in near real-time to clients interested in changes to one or more [namespaces](https://authorizer-tech.github.io/docs/overview/concepts/namespaces).
 
-An instance of an `access-watcher` is similar to the `watchserver` implementation called out in the [Google Zanzibar](https://research.google/pubs/pub48190/) paper (see Section 3).
+An instance of an `access-watcher` is similar to the `watchserver` implementation called out in the [Google Zanzibar](https://research.google/pubs/pub48190/) paper (see Section 3).
+
+# Getting Started
+If you want to setup an instance of the Authorizer platform as a whole, browse the API References, or just brush up on the concepts and design of the platform, take a look at the [official platform documentation](https://authorizer-tech.github.io/docs/overview/introduction). If you're only interested in running the access-watcher then continue on.
+
+## Setup and Installation
+> An access-watcher is not a standalone application. It is intended to be deployed alongside an existing [access-controller](https://github.com/authorizer-tech/access-controller) deployment. Setting up an access-watcher will fail if an existing access-controller has not been deployed.
+
+### Pre-compiled Binaries
+Download the [latest release](https://github.com/authorizer-tech/access-watcher/releases) an extract it.
+
+```console
+$ ./bin/access-watcher -config <config-path> -grpc-port 50052
+```
+
+## Next Steps...
+Take a look at the official [Documentation](https://authorizer-tech.github.io/docs/overview/introduction), [API Reference](https://authorizer-tech.github.io/docs/api-reference/overview) and [Examples](https://authorizer-tech.github.io/docs/overview/examples/examples-intro).
