+Creates a new custom rule, and makes it the active configuration scope.
+
+```lua
+rule ("name")
+```
+
+Rules contain the settings and property definitions for a single custom rule file. These settings include the target file extension, the command line format, and the build inputs and outputs.
+
+
+### Parameters ###
+
+`name` is the name for the rule, which must be unique for each rule specified. If a rule with the given name already exists, it is made active and returned.
+
+If no name is given, the current rule scope is returned, and also made active.
+
+By default, the rule name will be used as the file name of the generated rule files; be careful with spaces and special characters. You can override this default with [filename()](filename.md) and [location()](location.md).
+
+### Availability ###
+
+Premake 5.0 or later.
+
+### Examples ###
+
+Create a new rule named "luac". For a more complete example, see [Custom Rules](Custom-Rules.md).
+
+```lua
+rule "luac"
+  fileExtension ".lua"
+```
