-`environments` does not support configuring `server` options and some `dev` options, because multiple environments share the same server instance.
-:::
+## Available options
+
+`EnvironmentConfig` is a subset of the Rsbuild configuration, supporting most options.
+
+Since multiple environments share the same server instance, the following options are currently not supported in `EnvironmentConfig`:
+
+- `server.*`
+- `dev.watchFiles`
+- `dev.cliShortcuts`
+- `dev.setupMiddlewares`
