 You must configure which type of notifications you want to send _per agent_. If no types are selected, you will not receive notifications!
 
-Some agents may have specific configuration "gotchas" covered in their documentation pages.
+Note that some notifications are intended for the user who submitted the relevant request, while others are for administrators. For details, please see the documentation for the specific agent you would like to use.

+# Discord
+
+## Configuration
+
+{% hint style="info" %}
+In order to configure Discord notifications, you first need to [create a webhook](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks).
+
+In order for users to be mentioned in Discord notifications, they must have their [Discord user ID](https://support.discord.com/hc/en-us/articles/206346498-Where-can-I-find-my-User-Server-Message-ID-) configured in their user settings.
+{% endhint %}
+
+### Bot Username (optional)
+
+If you would like to override the name you configured for your bot in Discord, you may set this value to whatever you like!
+
+### Bot Avatar URL (optional)
+
+Similar to the bot username, you can override the avatar for your bot.
+
+### Webhook URL
+
+You can find the webhook URL in the Discord application, at **Server Settings → Integrations → Webhooks**.

+# Email
+
+{% hint style="info" %}
+The following email notification types are sent to _all_ users with the **Manage Requests** permission, as these notification types are intended for application administrators rather than end users:
+
+- Media Requested
+- Media Automatically Approved
+- Media Failed
+
+On the other hand, the email notification types below are only sent to the user who submitted the request:
+
+- Media Approved
+- Media Declined
+- Media Available
+
+{% endhint %}
+
+## Configuration
+
+### Sender Address (required)
+
+Set this to the email address you would like to appear in the "from" field of the email message.
+
+Depending on your email provider, this may need to be an address you own. For example, Gmail requires this to be your actual email address.
+
+### Sender Name (optional)
+
+Configure a friendly name for the email sender.
+
+### SMTP Host
+
+Set this to the hostname or IP address of your SMTP host/server.
+
+### SMTP Port
+
+Set this to a supported port number for your SMTP host. `465` and `587` are commonly used.
+
+### Enable SSL (optional)
+
+This setting should only be enabled for ports that use [implicit SSL/TLS](https://tools.ietf.org/html/rfc8314) (e.g., port `465` in most cases).
+
+For servers that support [opportunistic TLS/STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) (typically via port `587`), this setting should **not** be enabled.
+
+### SMTP Username & Password
+
+{% hint style="info" %}
+If your account has two-factor authentication enabled, you may need to create an application password instead of using your account password.
+{% endhint %}
+
+Configure these values as appropriate to authenticate with your SMTP host.
+
+### PGP Private Key & Password (optional)
+
+Configure these values to enable encrypting and signing of email messages using [OpenPGP](https://www.openpgp.org/). Note that individual users must also have their PGP public keys enabled in their user settings in order for PGP encryption to be used.
