+# SQLite Libraries
+
+This repository bundles a custom SQLite build for use as a dependency in iOS and Android apps via SPM, JitPack, pub and CocoaPods. Included are:
+
+- SQLite amalgamation, built with optimized settings and the following official extensions:
+  - snapshot
+  - fts5
+  - rtree
+  - math
+  - percentile
+  - geopoly
+  - carray
+  - series
+- USearch vector extension (SIMD vector search and various distance metrics)
+- SQLean's uuid extension (native UUID support, including UUIDv7)
+- SQLean's text extension (QoL helpers that exist in PostgreSQL)
+- GRDB (Swift SQLite driver, statically linked to custom SQLite)
+- SQLiteData (Swift query builder, built on GRDB)
+
+The dependencies are prepared via `scripts/setup.sh`, which downloads and organizes the relevant source code and adds a few shims.
+
