-## About ggsql
+Or install from within the editor: open the Extensions view, click the `...` menu, select "Install from VSIX...", and choose the downloaded file.
 
-ggsql is a SQL extension for declarative data visualization. It combines SQL queries with Grammar of Graphics-inspired visualization specifications, enabling you to query data and define visualizations in a single, composable syntax.
+## Learn More
 
-ggsql extends SQL with a `VISUALISE` clause that acts as a terminal operation, producing visualizations instead of relational data. Global aesthetic mappings can be specified directly after VISUALISE (e.g., `VISUALISE date AS x, revenue AS y`).
