+An extension of [Lua's require() function](http://www.lua.org/pil/8.1.html) which adds support for Premake modules and version checking.
+
+```lua
+require ("modname", "versions")
+```
+
+Premake will use its [extended set of module locations](Locating-Scripts.md) when locating the requested module.
+
+### Parameters ###
+
+`modname` is the name of the module to be loaded. See [Locating Scripts](Locating-Scripts.md) for more information about how Premake modules are located.
+
+`versions` is an optional string of a version requirements. See the examples below for more information on the format of the requirements string. If the requirements are not met, an error will be raised.
+
+
+### Returns ###
+
+The module object.
+
+
+### Availability ###
+
+Premake 5.0 or later.
+
+
+### Examples ###
+
+Require Premake version 5.0 or later.
+
+```lua
+require("premake", ">=5.0")
+```
+
+If no operator is specified, defaults to ">=". I think it is a little more readable to include it though.
+
+```lua
+require("premake", "5.0")
+```
+
+Require a version 5.0 alpha 3 or later.
+
+```lua
+require("premake", ">=5.0.0-alpha3")
+```
+
+Require anything between Premake version 5.1 and 6.0.
+
+```lua
+require("premake", ">=5.0 <6.0")
+```
+
+The same rules apply to third-party modules.
+
+```lua
+require("foo", ">=1.1")
+```
