 # Introduction to the client
 
-// EXPLAIN WHAT THE CLIENT DOES
+The client is what the main part of the application, it houses the interface and all of the scraping logic.
+
+## PWA
+
+The client can be optionally ran as a PWA. This can be hard to do correctly and really hard to reverse, so it's generally not recommended to do so if you don't have experience hosting PWA's.
+
+You can read more about it [here](../1.self-hosting/3.about-pwa.md).
+
+## Configuration
+
+The client has a decent amount of configuration options. You can view them all [here](./3.configuration.md).

-## Upgrade guide
+# Upgrade guide
 
-// UPGRADE GUIDE HERE
+## From `3.X` to `4.0.0`
+
+You will need the latest version of the proxy worker. Redeploy a new worker using [our self-hosting guide](../2.proxy/1.deploy.md).
+
+After you have the new worker, you will need to [get the new movie-web deployment files](https://github.com/movie-web/movie-web/releases/latest). **You CANNOT use the non-PWA version**. To upgrade safely without any complications, you need to update with `movie-web.pwa.zip`, Not the non-PWA version.
+
+In the future, you will **ALWAYS** need to go with the PWA option. You cannot downgrade to non-PWA version without facing many caching complications.
