 ### Windows
 
-1. Install the [Microsoft Visual C++ 2015 Redistributable](https://www.microsoft.com/en-us/download/details.aspx?id=52685). There is a good chance you already have this.
-2. Download the MSI package from the Releases and install it.
+Stl-thumb requires 64 bit Window Vista or later. [Download the installer .exe](https://github.com/unlimitedbacon/stl-thumb/releases/latest) for the latest release and run it.
 
-The installer will tell the Windows shell to refresh the thumbnail cache, however this does not always seem to work. If your icons do not change then try using the Disk Cleanup utility to clear the thumbnail cache.

 ### Linux
 
-Packages are being worked on for Arch and Debian/Ubuntu. Make sure your file manager is set to create previews for files > 1 Mb.
+Stl-thumb does not currently work with Nautilus (Gnome Files) 3.26. This is the default file manager in Ubuntu 18.04. [Nautilus sandboxes the thumbnailers](https://gitlab.gnome.org/GNOME/gnome-desktop/issues/7), preventing us from using GL. For now you will have to use a different file manager instead.
+
+#### Arch
+
+A package is available [in the AUR](https://aur.archlinux.org/packages/stl-thumb/). Install it manually or using your favorite AUR helper.
+
+```
+$ yay -S stl-thumb
+```
+
+#### Debian / Ubuntu
+
+[Download the .deb package](https://github.com/unlimitedbacon/stl-thumb/releases/latest) for your platform (usually amd64) and install it.
+
+```
+$ sudo dpkg -i stl-thumb_0.1.0_amd64.deb
