-There are two driver programs in `experimental/src` : `flat.cc` and `ivf_hack.cc`, which do exact-flat and kmeans-flat searches, respectively.
+# TileDB-Vector-Search: A C++ Support Library for Similarity Search with TileDB
 
-Documentation for these driver programs can be found in `experimental/src/README.md`.
+
+The TileDB-Vector-Search C++ Library is a header-only library with query, indexing, and utility functions to support vector similarity search on the TileDB universal database platform.
+
+The header files for the library are located in the `include` directory.
