-# sqlite-c
-
-A small SQLite inspired relational database engine built from scratch in C11.
-
-The project focuses on the storage mechanisms behind a database rather than reproducing SQLite's full feature set. It includes persistent storage built around fixed size pages, B tree table storage, a small SQL parser, an interactive shell, automated tests, a benchmark, and sanitizer coverage.
-
-The database file format is intentionally project specific and is not compatible with SQLite database files.

+
+**sqlite-c** is a learning project that implements a minimal relational database engine in C11. It follows SQLite's design ideas while keeping the storage engine small enough to study: fixed size pages, B-tree indexing, SQL parsing, and persistence.
+
+This project uses its own database file format. It is **not compatible with SQLite database files** and is not intended to replace SQLite.
