+# GUADEC 2020 Presentation Templates
+
+This repository contains templates usable for presentations for GUADEC 2020.
+
+The following commands will get you the template:
+
+```
+git clone https://gitlab.gnome.org/GNOME/presentation-templates.git
+cd presentation-templates/GUADEC/2020
+```
+
+Don't worry - you **don't need to write LaTeX**! Pandoc is easy! Please give it a
+try so we all can have consistent and pretty presentations.
+
+## How Can I Create a Presentation?
+
+You can create a presentation using Pandoc or LaTeX. Pandoc is way easier and
+recommended as it will be automatically translated into LaTex.
+
+Try it out; open your console, go to the directory where this document lies and
+type `make`. This will compile the `presentation.md` into `presentation.pdf` if
+you have pandoc installed.
+
+Just look into the md and pdf file to see how you can simply create your
+presentation. It's easy! Please try it out!
+
+> **Note**:
+>
+> You can use `make continuous` to automatically regenerate the PDF whenever you
+> touch the document. For that to work you'll need to have the `inotify-tools`
+> package installed.
+
+### Using Latex Directly
+
+You can also use LaTeX directly. Use the `make tex` command to compile the
+example tex document into a presentation.
