 ## Requirements
 
-- Go 1.15 or higher as build only dependency.
+- Go as build only dependency. We support the Go version(s) used in [continuous integration workflows](./tree/main/.github/workflows).
 - A suitable SQL server to use as data provider: PostgreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x.
 - The SQL server is optional: you can choose to use an embedded bolt database as key/value store or an in memory data provider.
