+# Plugins & Scheduler
+
+The SSO Manager includes a flexible background task runner and discovery system. Plugins are defined statically in your deployment configuration (`sso-secrets.js`) and run based on their defined `cron` schedule. 
+
+## Writing Custom Plugins
+
+You can write custom plugins to discover resources, manage internal state, or run automated scripts. Plugins must be placed in the `plugins/discovery/` directory of the SSO Manager node codebase.
+
+A plugin file must export a `discover` method.
+
+**Example Plugin (`plugins/discovery/my_plugin.js`):**
+
+```javascript
+module.exports = {
+  discover: async function(config) {
+    // The config object contains any keys passed in sso-secrets.js for this plugin.
+    
+    // Perform discovery logic, hit external APIs, etc.
+    const resources = [
+      {
+        slug: 'my-custom-resource-1',
+        name: 'My Resource 1',
+        kind: 'Host',
+        metadata: {
+          ip: '10.0.0.100',
+          source: 'My Custom Plugin'
+        }
+      }
+    ];
+    
+    // Return the discovered resources array. The discovery reconciler will 
+    // automatically save these to the Network Discovery database.
+    return resources;
+  }
+};
+```
+
+## Configuring Plugins
+
+In your `sso-secrets.js` file, add your plugin to the `discovery.plugins` object:
+
+```javascript
+module.exports = {
+  // ...
+  discovery: {
+    plugins: {
+      my_plugin: {
+        enabled: true,
+        cron: "0 * * * *", // Run every hour
+        my_custom_key: "my_custom_value" // Passed to the config argument in discover()
+      }
+    }
+  }
+  // ...
+};
+```
+
+### Overriding Timing and Enable/Disable
+
+From the **Plugins & Scheduler** tab in the Directory Dashboard, you can override the schedule and enable/disable state for each plugin. These overrides take precedence over `sso-secrets.js` and are stored internally.
+
+## Scheduler Internals
+
+The scheduler uses BullMQ backed by Redis to manage execution. It automatically performs garbage collection on stale network resources (resources not updated in > 7 days) and triggers your plugins at the defined intervals.
