 Telegram DM bridge for pi.
 
+This repository is a fork of the original [`badlogic/pi-telegram`](https://github.com/badlogic/pi-telegram).
+It started from upstream commit [`cb34008460b6c1ca036d92322f69d87f626be0fc`](https://github.com/badlogic/pi-telegram/commit/cb34008460b6c1ca036d92322f69d87f626be0fc) and has since diverged substantially.
+
+## What Changed In This Fork
+
+Compared to upstream commit `cb34008`, this fork significantly extends and hardens the extension.
+
+- Better Telegram control UI, including an improved `/status` view with inline buttons for model and thinking selection
+- Interactive model selection improvements, including scoped model lists and thinking-level control for reasoning-capable models
+- Queueing and interaction upgrades, including queue previews, reaction-based prioritization/removal, media-group handling, and safer dispatch behavior
+- Markdown and reply rendering improvements, with richer formatting support and multiple fixes for incorrect Telegram rendering and chunking edge cases
+- Streaming, attachment, and delivery workflow hardening, including more robust preview updates and file handling
+- General runtime polish, bug fixes, and refactors across pairing, command handling, and Telegram session behavior
+
+In short: this fork is no longer just a repackaged copy of upstream; it is a feature-expanded and bug-fixed Telegram frontend for pi.
