 ## Installation
+To install a stable version of this theme, please refer to update instructions
+of your TeX distribution. Trigon has been on
+[CTAN](https://ctan.org/pkg/beamertheme-trigon) since March 2021. For users of
+typical TeX distributions (TexLive, MacTeX, MikTeX), simply updating your
+package list should install trigon on your system.
+
+If you want to use the cutting-edge development version of Trigon, you can
+install it manually by following these steps:
+1. **Download the source** using a `git clone` of the [Trigon
+   repository](https://gitlab.com/thlamb/beamertheme-trigon) or as a [zip
+   archive](https://gitlab.com/thlamb/beamertheme-trigon/-/archive/master/beamertheme-trigon-master.zip)
+2. **Compile the style files** by running `make sty` inside the downloaded
+   directory. (Or run LaTeX directly on `source/trigontheme.ins`.)
+3. **Move the resulting `*.sty` files** to the folder containing your
+   presentation. To use Trigon with many presentations, run `make install` or
+   move the `*.sty` files to a folder in your TeX path instead.
+4. **Use the theme** by declaring `\usetheme{trigon}` in the preamble of your
+   document.
+
+### Overleaf
+Trigon is not yet included in default TexLive installations. Therefore, it is
+not natively available on [Overleaf](https://overleaf.com) (it should be
+included at the end of Q3 2021). In the meantime, a template project was made
+and will be kept updated with the current master version. To use it, follow
+[this link](https://www.overleaf.com/read/dvbnhdcbfknk), copy the project
+(menu/copy project) and modify it to your needs.
+
+Once the theme will be properly included to Overleaf, a basic template will be
+added to the Overleaf theme gallery.

+  Sometimes, it is useful to add slides at the end of your presentation to
+  refer to during audience questions.
+
+  The best way to do this is to include the \verb|appendixnumberbeamer|
+  package in your preamble and call \verb|\appendix| before your backup slides.
+
+  \themename will automatically turn off slide numbering and progress bars for
