 ## Running Prism Standalone
 
 Prism can be executed as a stand alone binary and will present a basic UI for listing jobs, and job status.
+This is an optional mode for Prism that is useful for demos or rapid iteration.
+It is not a requirement for using Prism in the Java or Python SDKs.
 
-It's recommended to use a released version of Prism, such as downloading one from the [Github Release](\(https://github.com/apache/beam/releases/tag/v{{< param release_latest >}})), or to build one from the latest version of the Beam Go module, using a [recent version of Go](https://go.dev/dl/).
+This can be done in two ways, downloading an asset from the github release, or building the binary locally with Go installed.
+
+In either case, Prism serves a JobManagement API endpoint, and a Webpage UI locally.
+Jobs can be submitted using `--runner=PortableRunner --endpoint=<endpoint address>` and monitored using the webpage UI.
+
+Example output from the Prism binary:
 
 ```
-go run github.com/apache/beam/sdks/v2/go/cmd/prism@latest
+2024/09/30 09:56:42 INFO Serving JobManagement endpoint=localhost:8073
+2024/09/30 09:56:42 INFO Serving WebUI endpoint=http://localhost:8074
 ```
 
-In either case, Prism serves a JobManagement API endpoint, and a Webpage UI locally.
-Jobs can be submitted using `--runner=PortableRunner --endpoint=<endpoint address>` and monitored using the webpage UI.
+The binary has the following optional flags:
+
+* `--job_port` sets the port for the Job management server (defaults to 8073)
+* `--web_port` sets the port for the web ui (defaults to 8074)
+* `--serve_http` enables or disables the web ui (defaults to true)
+* `---idle_shutdown_timeout` sets a duration that Prism will wait for a new job before automatically shutting itself down. Uses duration format like `10s`, `5m`,`2h`. Defaults to not shutting down.
+
+### Download a release asset
+
+This approach doesn't require other dependencies or runtimes installed.
+This is recommended if you want to deploy Prism on some other machine.
+
+Navigate to the latest [Beam Release Github page](https://github.com/apache/beam/releases/tag/v{{< param release_latest >}}), scroll to the bottom, and download the correct asset for where you want to run Prism.
 
+For example, if you want to execute Prism on a newer MacBook, you'd download the `darwin-arm64` asset. For executing on many cloud machines, you'd download the `linux-amd64` asset.
+
+This
+requires downloading the right asset for the machine Prism will run on, such as your development
+machine.
+
+Simply unzip, and execute.
+
+### Build from the release with Go.
+
+This approach requires a [recent version of Go installed](https://go.dev/dl/).
+This is recommended if you only want to run Prism on your local machine.
+
+You can insall Prism with `go install`:
+
+```sh
+go install github.com/apache/beam/sdks/v2/go/cmd/prism@latest
+prism
+```
+
+Or simply build and execute the binary immeadiately using `go run`:
+
+```sh
+go run github.com/apache/beam/sdks/v2/go/cmd/prism@latest
+```
