+# Doris and SelectDB SQL assistance
+
+The function catalogue is derived from the Apache Doris 2.1 and 3.x SQL manuals.
+SelectDB connections use the Doris capability family through `jdbcDialect.ts`.
+
+Regenerate the catalogue from an Apache `doris-website` checkout:
+
+```sh
+node scripts/generate-doris-functions.mjs /path/to/doris-website
+```
+
+The generated file records the source revision and per-function documentation
+links. `documentedIn` records documentation coverage, not a minimum server
+version: the 3.x manuals also contain functions added after 3.0.
