+# tuos-presentation
+A LaTeX class (based on the [beamer class](https://www.ctan.org/pkg/beamer)) 
+that implements the cooperate style of the
+[Software Assurance & Security Research Team Sheffield](https://logialhacking.com).
+
+## Prerequisites 
+* The `lh-logo` style.
+
+## Installation 
+* Copy the various `*.sty` and `*.cls` files into your `texmf` tree. 
+
+## Usage
+The `lh-presentation` class (respectively, a beamer theme) is a
+customised setup of the
+[beamer class](https://www.ctan.org/pkg/beamer).  Thus, please see the
+beamer documentation for its detailed use. In general, you can either
+use the class file (i.e., `\documentclass{lh-presentation}` or use
+`\usetheme{lh-presentation}` in a regular beamer setup.
+
+Moreover, a few new commands are provided that generate standard
+slides such as `\PartFrame{}`, `\ThanksFrame{}`, or `\CopyrightFrame`.
