+      option) any later version.
+
+2. The documentation of the package is also dual-license. Again, you can choose
+   between two options:
+
+   1. You can use the GNU Free Documentation License, Version 1.3 or any later
+      version published by the Free Software Foundation.

-Beamer - A LaTeX class for producing presentations
-==================================================
+# Beamer - A LaTeX class for producing presentations
 
-* See the documentation in [doc/beameruserguide.pdf](http://mirrors.ctan.org/macros/latex/contrib/beamer/doc/beameruserguide.pdf) for a user manual.
-* See the information in [doc/licenses/LICENSE](http://mirrors.ctan.org/macros/latex/contrib/beamer/doc/licenses/LICENSE) for information on licensing.
+## Overview
 
-This package also uses [translator](https://github.com/josephwright/translator/), a package for translating
-words in LaTeX. We welcome new translations.
+The `beamer` class is focussed on producing (on-screen) presentations, along
+with support material such as handouts and speaker notes. Content is created
+in a `frame` environment, each of which can be divided up into a number of
+slides (actual output pages). A simple 'action' notation is used to specify
+which material appears on each slide within a frame. The class supports a
+range of environments to enable complex slide relationships to be constructed.
+
+The appearance of slides is controlled by a template system. Many of the
+elements of slides can be adjusted by setting simple key-based values in
+the preamble. More complex changes can be implemented by altering specific,
+targeted definitions without needing to re-write entire blocks of code. This
+allows a variety of visual appearances to be selected for the same content
+source.
+
+## License
+
+The `beamer` class is made available under the LaTeX Project Public License
+(LPPL) and the GNU Public License (GPL). See the information in
+[LICENSE](LICENSE.md) for information on licensing.
