 # Telegram Mini App Template
-## Prerequisites
+Template for implementing Telegram Bots with Mini Apps. Deployed instance available at [@tg_mini_app_template_bot](https://t.me/tg_mini_app_template_bot).
+
+## Features
+- Example of creating [Inline Keyboard](https://core.telegram.org/bots/features#inline-keyboards) to interact with the user. Keyboard creation can be found in [main.go](api/main.go)
+- Example of adjusting UI styles to the user's current color theme using [ThemeParams](https://core.telegram.org/bots/webapps#themeparams). CSS variable usage can be found in [App.css](ui/src/App.css)
+- Example of interaction with [telegram-web-app.js](https://core.telegram.org/bots/webapps#initializing-mini-apps) to show a native alert. Script usage can be found in [App.js](ui/src/App.js) 
+- [Local environment](#local-environment) with [docker-compose](https://docs.docker.com/compose/), that serves traffic over HTTPS proxy and automatically applies UI changes without rebuilding the container
+- [Continious deliviery](#production-deployment) to [Google Cloud Platform](https://cloud.google.com/)
+
+## Setup prerequisites
 Telegram Bot token is required to interact with [Telegram Bot API](https://core.telegram.org/bots). To get one, сreate a bot using [@BotFather](https://t.me/botfather).
 
 ## Local environment
 This repository provides an easy-to-use local development environment. Using it you can start writing your bot business logic without spending time on the environment.
 
 Local environment includes:
-- [ngrok](https://ngrok.com/) reverse proxy to server local mini-app and bot deployment over HTTPs
+- [ngrok](https://ngrok.com/) reverse proxy to server local mini-app and bot deployment over HTTPS
 - [nginx](https://www.nginx.com/) reverse proxy to host both API and UI on one ngrok domain and thus fit into the [free plan](https://ngrok.com/pricing)
 - React fast refresh to avoid rebuilding docker container on each change of the UI code
