 * Metadata should allow for collections, want to read integration from 3rd party services, genres.
 * Ability to manage users, access, and ratings
-* Expose an OPDS API/Stream for external readers to use
-* Allow downloading files directly from WebApp
 
 
 ## How to Deploy
 * Build kavita-webui via ng build --prod. The dest should be placed in the API/wwwroot directory
 * Run publish command

+1. Unzip the archive for your target OS
+2. Place in a directory that is writable. If on windows, do not place in Program Files
+3. Open appsettings.json and modify TokenKey to a random string ideally generated from [https://passwordsgenerator.net/](https://passwordsgenerator.net/)
