+Loro is a fast [CRDT](https://crdt.tech/) framework with built-in end-to-end encryption ability. 
+
+It provides a set of data structures that can automatically sync without any conflict. With end-to-end encryption addon, all data can be encrypted without losing the ability to collaborate with the others. It aims to be the engine for building [local-first software](https://www.inkandswitch.com/local-first/).
+
+
+# Why Loro
+
+- 🚀 It is pretty fast
+- 🔒 [WIP] Security built-in
+- 💻 Syncing data made easy
+- 📜 Preserve all history with low overhead
+- 🪐 [WIP] Time travel the history in milliseconds
+
+Loro supports a variety of data structures and CRDT algorithms. 
+
+- It supports the most used `List`, `Map` and `Text`. 
+- [TODO] [Peritext](https://www.inkandswitch.com/peritext/) for fine-grind rich text operations
+- [TODO] [Moveable Tree]() for directory-like moving operations 
+- [WIP] Super fast version checkout and undo/redo 
+
+
