-Lykia is a toy multi-model database basically written for educational purposes.
+Lykia is a document database management system built for educational purposes. The famous book, Crafting Interpreters, was the main source of inspiration for the project. It turned into a database, though.
 
 ## Overview
-- Written in Rust
-- A weird scripting and query language, combination of JavaScript and SQL. Built based on the language "Lox" which is explained in the famous book, Crafting Interpreters.
+- 100% safe Rust, #BlazinglyFast
+- A weird scripting and query language, combination of JavaScript and SQL. The language is a separate module thus can be used without the database.
 - A subset of JSON data types in both scripting language itself and storage
 - In-disk and in-memory storage
 - ACID compliance
 - Replication
 
 ## Roadmap
 
-- [x] Core scripting language
+- [x] Core scripting language + DML/DDL SQL
 - [x] A minimal standard library
-- [x] DML/DDL SQL
-- [x] Event loop, client-server communication
-- [x] Minimal playground app
+- [x] Runtime 
+- [x] Playground app
 - [ ] Query binding and planning (in progress)
-- [ ] Bitcask storage engine
+- [ ] LSM storage engine (based on [mini-lsm](https://github.com/lykia-rs/mini-lsm)) 
 - [ ] MVCC for transaction management (based on [mini-lsm](https://github.com/lykia-rs/mini-lsm))
 - [ ] Plan optimization
------------------------------------------
-- [ ] LSM storage engine (based on [mini-lsm](https://github.com/lykia-rs/mini-lsm))

+## More ambitious roadmap: 
+
 - [ ] Basic replication with Raft
