-# Havasu Specification
+# Havasu Table Format Specification
+
+Havasu is a spatial table format built on top of Apache Iceberg. Havasu supports ACID transactions, schema evolution, and time travel on spatial data including geometries and rasters. Havasu stores spatial data in Apache Parquet format on cloud storage, which is very cost effective and highly decoupled with computation.
 
 This repository contains the Havasu specification, which is a formal description of the Havasu table format. The specification is written in Markdown and can be found in the [spec.md](spec.md) file.
+
+A reader and writer implementation of Havasu table format specification is available in Wherobots [SedonaDB](https://docs.wherobots.services/latest/tutorials/sedonadb/introduction/). The detailed usage of SedonaDB Havasu operations can be found on [Wherobots Havasu References](https://docs.wherobots.services/latest/references/havasu/introduction/).
