+Open-UI OPL syntax
+==================
+
+This is a syntax file, which I was created back than in 2011 for a most
+probably dead language for user interface called Open-UI for Windows. Interface
+have to be written in Pascal-alike language called OPL. Syntax highlight is for
+this specific language.
+
+This repository is just for a proof, that it is fairly easy to prepare syntax
+highlighting for an exotic language.
+
+Installation
+------------
+
+To install it, any kind of Vim package manager can be used, like NeoBundle_,
+Pathogen_, Vundle_ or vim-plug_.
+
+For manual installation, copy subdirectories from this repository to your
+``~/.vim`` directory. Your ``.opl`` files should now have proper syntax
+highlighting. You can check it by opening any ``.opl`` file, and see its file
+type under vim in *ex* mode:
+
+.. code:: vim
+
+   :set ft
+   "a message should appear:
+     filetype=openui-opl
