 ## Why Gatus?
@@ -125,6 +141,7 @@ fixing the issue before they even know about it.
 
 ## Features
 The main features of Gatus are:
+
 - **Highly flexible health check conditions**: While checking the response status may be enough for some use cases, Gatus goes much further and allows you to add conditions on the response time, the response body and even the IP address.
 - **Ability to use Gatus for user acceptance tests**: Thanks to the point above, you can leverage this application to create automated user acceptance tests.
 - **Very easy to configure**: Not only is the configuration designed to be as readable as possible, it's also extremely easy to add a new service or a new endpoint to monitor.

+### Endpoints
+Endpoints are URLs, applications, or services that you want to monitor. Each endpoint has a list of conditions that are
+evaluated on an interval that you define. If any condition fails, the endpoint is considered as unhealthy.
+You can then configure alerts to be triggered when an endpoint is unhealthy once a certain threshold is reached.

+### External Endpoints
+Unlike regular endpoints, external endpoints are not monitored by Gatus, but they are instead pushed programmatically.
+This allows you to monitor anything you want, even when what you want to check lives in an environment that would not normally be accessible by Gatus.
+
+For instance:
+- You can create your own agent that lives in a private network and pushes the status of your services to a publicly-exposed Gatus instance
+- You can monitor services that are not supported by Gatus
+- You can implement your own monitoring system while using Gatus as the dashboard

+| `external-endpoints[].group`   | Group name. Used to group multiple endpoints together on the dashboard. <br />See [Endpoint groups](#endpoint-groups). | `""`          |
+| `external-endpoints[].token`   | Bearer token required to push status to.                                                                               | Required `""` |
+| `external-endpoints[].alerts`  | List of all alerts for a given endpoint. <br />See [Alerting](#alerting).                                              | `[]`          |
+
+Example:
+```yaml
+external-endpoints:
+  - name: ext-ep-test
+    group: core
+    token: "potato"
+    alerts:
+      - type: discord
+        description: "healthcheck failed"
+        send-on-resolved: true
+```
+
+To push the status of an external endpoint, the request would have to look like this:
+```
+POST /api/v1/endpoints/{key}/external?success={success}
+```
+Where:
+- `{key}` has the pattern `<GROUP_NAME>_<ENDPOINT_NAME>` in which both variables have ` `, `/`, `_`, `,` and `.` replaced by `-`.
+  - Using the example configuration above, the key would be `core_ext-ep-test`.
+- `{success}` is a boolean (`true` or `false`) value indicating whether the health check was successful or not.
+
+You must also pass the token as a `Bearer` token in the `Authorization` header.

 ### Alerting
 Gatus supports multiple alerting providers, such as Slack and PagerDuty, and supports different alerts for each
 individual endpoints with configurable descriptions and thresholds.
 
-> 📝 If an alerting provider is not properly configured, all alerts configured with the provider's type will be
-ignored.
+Alerts are configured at the endpoint level like so:
 
 | Parameter                    | Description                                                                    | Default       |
