+# SQUIRREL
+SQL Query Util-Izing Rust's Reliable and Efficient Logic
+
+---
+
+## About
+This is a SQL database written in Rust. It will be based off of (and hopefully be made wire-compatible with) PostgreSQL's syntax.
+
+## Feature roadmap
+
+[ ] Table creation via CREATE with varchar & integer datatype
+
+[ ] SELECT * query 
+
+[ ] SELECT (filtered columns) query 
+
+[ ] Primary Keys via B+ Tree
+
+[ ] Foreign Keys
+
+[ ] Some form of JOINs
+
+[ ] Support [Postgres' messaging system](https://www.postgresql.org/docs/current/protocol-flow.html#id-1.10.6.7.3) (wire compatability)
+ 
+... other stuff is TBD
