+The Fix command is experimental and requires setting the `--power` option to be used.
+You can pass it explicitly or set it globally by running:
+
+    scala-cli config power true
+:::
+
+The `fix` command scans your project for `using` directives and extracts them into the `project.scala` file placed in the project root directory.
+This allows to fix warnings tied to having `using` directives present in multiple files.
+Additionally, `fix` will format the result file, thus allowing to quickly spot configuration options that may be duplicated.
+
+Files containing `using target` directives, e.g. `//> using target.scala 3.0.0` will not be changed by `fix`.
+
+The command respects the original scope of each extracted directive and will transform them into their `test.` equivalent if needed.
