-Webhooks allow applications to subscribe to Moodle events.
+Adding Webhooks to Moodle.
+The Webhooks feature allows applications to receive real-time notification of changes to certain data.
 
-**Attention!**:
-This plugin is in active development.
+Using Webhooks, your application will be able to receive notifications of changes to selected topics and their fields.
+Because of this, you do not have to rely on continuous or even periodic requests to check for updates.
+Notifications about Webhooks updates are sent as POST requests to the callback URL you specified.
+Notifications can indicate the very fact of a field change or include a new value.
 
-## Installation
+Features:
 
-Get the installation package in any of the available methods:
+* Use any number of services for notification;
+* Customizing each external service;
+* Interception of all events in the Moodle system;
+* Use a secret phrase to authenticate requests;
+* [JSON](https://en.wikipedia.org/wiki/JSON) - Format of outgoing data;
 
-* [GitHub Releases](https://github.com/valentineus/moodle-webhooks/releases).
-* [Compilation from the source code](#build).
+## Documentation
 
-## Build
-
-Self-assembly package is as follows:
-
-* Clone the repository:
-```bash
-git clone https://github.com/valentineus/moodle-webhooks.git moodle-webhooks
