+### Base Requirements
+
+If using Docker image for option (a) for the provider, the Docker runtime is required.
+
+Otherwise, Node.js and Yarn are required. You will also need to clone the repository.
+
 ### 1. Set up the provider
 
+There are two options for the provider, an always running POT generation HTTP server, and a POT generation script invoked when needed. The HTTP server option is simpler, and comes with a prebuilt Docker image. **You only need to choose one option.**
+
+#### (a) HTTP Server Option
+
 The provider is a Node.js HTTP server. You have two options of running it: as a prebuilt docker image, or manually as a node application.

 docker run --name bgutil-provider -d -p 4416:4416 brainicism/bgutil-ytdlp-pot-provider

+
+**Endpoints**

+- **POST /get_pot**: Accepts a `visitor_data` (unauthenticated), `data_sync_id` (authenticated) or an empty body in the request body. If no identifier is passed, a new unauthenticated `visitor_data` will be generated. Returns `po_token` and the associated identifier `visit_identifier`.
+- **POST /invalidate_caches**: Resets the PO token cache, forcing new tokens to be generated on next fetch
+</details>
+
+#### (b) Generation Script Option
+
+The generation script needs to be transpiled to Javascript before it can be used by the plugin.

+```shell
+cd server/
+yarn install --frozen-lockfile
+npx tsc

-### Server-less
+If using option (a) HTTP Server for the provider, use yt-dlp like normal 🙂.
 
-If you don't need to programatically generate POTs, you can use the `generate_once` script to generate a POT.
+If using option (b) script for the provider, you need to pass extractor arguments including the path to the generation script for each yt-dlp call. Make sure to point to the transpiled version, `server/build/generate_once.js`
 
 ```shell
-cd server/
-yarn install --frozen-lockfile
-npx tsc
-node build/generate_once.js ## can pass "-v [visitor_data]" or "-d [data_sync_id]" if needed as well
