+You should now be able to connect to VATSIM! The next steps are to
+[create a .desktop file](#optional-create-a-desktop-entry-for-swift-in-proton) for convenience, or setting
+up a [separate Linux swift client](#optional-installing-swift-on-linux) to connect to the Windows swift client.
+There may not be much of a benefit for doing so, but you do get to use a native Linux client. If you are not interested
+in any of this, just skip to [testing swift](#testing-swift).
+
+### (Optional) Create a Desktop Entry for swift in Proton
+
+Creating a [desktop entry](https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html)
+should make opening the swift client easier as you will not have to find the location manually each time.
+
+These files will go into `~/.local/share/applications/`, but you can create multiple directories inside it to make it
+easier to manage your custom Desktop Entries that you manually created. For example on my system, I stored this entry
+under
+
+```
+~/.local/share/applications/wine/Programs/swift/
+```
+
+Create a Desktop Entry inside a location specified above, with a text editor of your choice. The name of the file is
+irrelevant as long as it has the `.desktop` extension.
+
+When creating the `.desktop` file, make sure that the directory is correct for the swift version you have installed.
+
+```desktop copy filename="swiftlauncher.desktop"
+[Desktop Entry]
+Name=Swift Launcher (Proton)
+Exec=protontricks -c "wine C:/Program\\ Files/swift-0.12-64bit/bin/swiftlauncher.exe" 1250410
+Type=Application
+StartupNotify=true
+Categories=Game;Simulation;
+```
+
+Then make sure to update the database for desktop entries by running this command in the terminal
+
+```shell copy
+update-desktop-database ~/.local/share/applications
+```
+
+You should now be able to find the Swift Launcher in your Desktop Environment's application launcher.

+If you haven't used VATSIM before, you should read up on the
+[guides](https://vatsim.net/docs/basics/getting-started), but if not, you can join as an observer at a busy airport,
+with ATC preferably ([map for convenience](https://map.vatsim.net/)), and hopefully you should hear ATC and
