-The theme will be made available directly from CTAN and Overleaf once finished

 ## Features
 
 - Multiple style variations for title, section and regular slides
+- Dark theme
 - Many convenient options (numbering style, toggle section slides, title font changes,...)
 - Looks better on 16:9 format, but supports 4:3 as well
 - Lightweight (does not require lots of additional packages)

 ## 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.

+\subsection{Installing from CTAN}
+The latest stable version of \themename is available on
+\href{https://ctan.org/pkg/beamertheme-trigon}{CTAN} and should now be part of
+the usual \TeX\ distibutions (\TeX\ Live, Mac\TeX\ , Mik\TeX\ ), under the name
+\textit{beamertheme-trigon}. It means that if your distribution is kept
+up-to-date, the package should normally be already installed on your system. If
+this is not the case, consider updating the packages of your Tex distribution.
+
+For \TeX\ Live and Mac\TeX\ users, this usually means running
+\begin{lstlisting}
+tlmgr update --all
+\end{lstlisting}
+, or if administrative privileges are required
+\begin{lstlisting}
+sudo tlmgr update --all
+\end{lstlisting}
+
+For Mik\TeX\ users, please refer to \href{https://miktex.org/howto/update-miktex}{the official Mik\TeX\ documentation}.

+As of the writing of this documentation (September 5,2021), the theme is not yet
+natively supported on Overleaf. It will be added once they update their package
+list, which is planned for end of Q3 2021
+(\href{https://gitlab.com/thlamb/beamertheme-trigon/-/issues/1#note_558034187}{see

-\themename will be proposed for integration on \href{https://www.ctan.org}{CTAN}
-shortly. It will then hopefully be integrated to texlive, miktex, etc. In the
-meantime, only the installation from Gitlab is possible.
+In the meantime, a \href{https://www.overleaf.com/read/dvbnhdcbfknk}{template
