+### Discord Application
+
+A Discord Application is required for PYRSS to work, as it will provide the Discord Bot used to send RSS content.
+
+Save the key and secret as these environment variables:
+- `DISCORD_KEY`
+- `DISCORD_SECRET`
+
+#### Create the Application
+
+1. Navigate to the Discord Developer Portal, on the applications page: https://discord.com/developers/applications.
+2. Create an App using the "New Application" button.
+
+#### Installation
+
+Now that you've created an Application, there are some required settings that you need to configure, navigate to the "Installation" tab from the sidebar.
+
+Under "Installation Contexts", ensure that only the `Guild Install` checkbox is checked.
+
+![An example image showing the "Guild Install" checkbox as checked.](apps/static/images/installation_contexts.png)
+
+This application is designed to be used in Guilds, so this setting is important.
+
+#### OAuth2
+
+Navigate to the "OAuth2" tab from the sidebar.
+
+1. Head to the "Redirects" section and select "Add Redirect"
+2. Add a redirect with this format: `PROTOCOL://HOST_ENDPOINT/oauth2/login/redirect` where `PROTOCOL` is either `http` or `https`, and the `HOST_ENDPOINT` is either an IP:PORT combination or web domain.
+
+Now you need to generate an Invite URL that you can use to add the Bot to your Discord Server.  Navigate to the "OAuth2 URL Generator" section.
+
+1. Check the checkboxes for these scopes:
+    - identify
+    - guilds
+    - applications.commands
+    - bot
+2. There should be a select box below the "scopes" section. Select the redirect URL that you created earlier.
+3. Check the checkboxes for these bot permissions:
+    - View Channels
+    - Send Messages
+    - Embed Links
+    - Attach Files > TODO: verifiy?
+    - Use Slash Commands
+4. "Integration Type" select `Guild Install`
+5. Copy and save the generated URL
+
+You need to create an environment variable for the generated url, `DISCORD_OAUTH2_URL`.
+
+> TODO: write for `DISCORD_INVITE_URL` env var
+
+#### Bot
+
+Navigate to the "Bot" tab from the sidebar.
+
+Take note of the Token, you may need to use the "Reset Token" button to get one.
+You will need to create an environment variable `BOT_TOKEN` for PYRSS.
+
+Navigate to the "Privilaged Gateway Intents" and ensure these intents are enabled:
+
+- > TODO
+
+### Database
+
+Use environment variables to specify a database, otherwise an sqlite database file will be created and used by default.
+
+#### Environment Variables
+
+`DB_ENGINE` - [Supported database engines](https://docs.djangoproject.com/en/5.0/ref/settings/#engine)  
+`DB_NAME` - Name of the database  
+`DB_USER` - Name of the database user  
+`DB_PASSWORD` - Password of the database user  
+`DB_HOST` - Host IP of the database  
+`DB_PORT` - Host Port of the database
+
+> **Note**  
+>  If `DB_ENGINE` is not specified, the other database related environment variables will be ignored, and the default sqlite database will be used with a generated `db.sqlite3` file.
+
+### Admin Account
+
+Create an environment variable `SUPERUSER_IDS` and add comma separated Discord snowflake User IDs. When logged-in, these users will be able to access the admin panel.
