+Specifies the include directories to parse last per the toolset ordering and marks the directory as an external include directory.  If the exporter or toolset
+does not support include directory ordering, these directories are added to the external include directory path.
+
+```lua
+includedirsafter { "paths" }
+```
+
+### Parameters ###
+
+`paths` specifies a list of include file search directories. Paths should be specified relative to the currently running script file.  Search order is evaluated from
+right to left.
+
+### Applies To ###
+
+Project configurations.  GCC and Clang are the only toolsets supporting the ordering functionality in the gmake, gmake2 and Codelite exporters.  All exporters and toolsets
+support appending the directories to the external include directories.
+
+### Availability ###
+
+Premake 5.0 or later.
+
+### Examples ###
+
+Define two include file search paths.
+
+```lua
+includedirsafter { "../lua/include", "../zlib" }
+```
+
+You can also use wildcards to match multiple directories. The * will match against a single directory, ** will recurse into subdirectories as well.
+
+```lua
+includedirsafter { "../includes/**" }
+```
+
