TL;DR — Telegram is a free, encrypted messaging app with 900M+ monthly users. To start: pick the official Android/iOS/Desktop/Web client, register with your phone number, then use the LetsTG search box on the homepage to find groups, channels, bots and movie resources. Read on for the step-by-step guide.
Telegram (TG) is one of the fastest-growing messaging apps worldwide, with over 900 million monthly active users. This page covers everything from Telegram download, registration, the web version (Telegram Web) to channels (Telegram Channel), groups (Telegram Group), bots (Telegram Bot) and massive resource collections — a one-stop tutorial to find any TG resource you need.
Telegram is a cross-platform encrypted messaging app founded by Pavel Durov. It offers end-to-end encryption, cloud sync, 2GB file transfers, massive channels/groups (up to 200K members) and an open Bot API.
Pick the right Telegram client for your device: Android (Google Play / APK), iOS (App Store), Windows / macOS / Linux Desktop, or the Web version (web.telegram.org).
Channels are one-to-many broadcasts (only admins post) while Groups are many-to-many chats. Pick a Channel for newsletters, a Group for community discussions.
Use a directory like LetsTG to discover quality groups and channels by category, language and country. The in-app search has limited reach.
Telegram Bots automate tasks (translation, weather, payments). Mini Apps run directly inside Telegram for richer interactions, like games and dashboards.
