+# Glint: Vectorized and Data Driven Code Generation Query Engine in Java
 
 ## Description
 
-Glint is a minimal SQL query engine with vectorized and query compilation support in Java.
-
-Following in the tradition of the new movement of modular database architectures
-Glint has no catalog or data management; its only capability is turning SQL queries
-into Java code that is then compiled and executed; think Calcite not Spark.
+Glint is a minimal SQL query engine written in Java, it currently supports
+vectorized execution and we plan to add further support for code generation.

 You will probably want to use an IDE like IntelliJ or what I personally recommend VSCode with the
 Java pack at least for working with the codebase but you are free to use ed or nano as well.
