+# Telebugs for Ruby
 
-TODO: Delete this and the text below, and describe your gem
+Simple error monitoring for developers. Monitor production errors in real-time
+and get them reported to Telegram with Telebugs.
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/telebugs`. To experiment with that code, run `bin/console` for an interactive prompt.

-## Installation
+## Introduction
+
+Any Ruby application or script can be integrated with
+[Telebugs](https://telebugs.com) using the `telebugs` gem. The gem is designed
+to be simple and easy to use. It provides a simple API to send errors to
+Telebugs, which will then be reported to your Telegram project. This guide will
+help you get started with Telebugs for Ruby.
 
-TODO: Replace `UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG` with your gem name right after releasing it to RubyGems.org. Please do not do it earlier due to security reasons. Alternatively, replace this section with instructions to install your gem from git if you don't plan to release to RubyGems.org.
+For full details, please refer to the [Telebugs documentation](https://telebugs.com/new/docs/integrations/ruby).
+
+## Installation
 
 Install the gem and add to the application's Gemfile by executing:
 
-    $ bundle add UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+```sh
+bundle add telebugs
+```
 
 If bundler is not being used to manage dependencies, install the gem by executing:
 
-    $ gem install UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+```sh
+gem install telebugs
+```
 
 ## Usage
 
-TODO: Write usage instructions here
+This is the minimal example that you can use to test Telebugs for Ruby with your
+project:
+
+```rb
+require "telebugs"
+
+Telebugs.configure do |c|
+  c.api_key = "YOUR_API_KEY"
+end
+
+begin
+  1 / 0
+rescue ZeroDivisionError => e
+  Telebugs.notify(error: e)
+end
+
+sleep 2
+
+puts "An error was sent to Telebugs asynchronously.",
+  "It will appear in your dashboard shortly.",
+  "A notification was also sent to your Telegram chat."
+```
+
+Replace `YOUR_API_KEY` with your actual API key. You can ask
+[@TelebugsBot](http://t.me/TelebugsBot) for your API key or find it in
+your project's dashboard.
