+| Warning: You are running an unofficial Flatpak version of Visual Studio Code !!! |
+------------------------------------------------------------------------------------
+
+Please open issues under: https://github.com/flathub/com.visualstudio.code/issues
+
+
+This version is running inside a container and is therefore not able
+to access SDKs on your host system!
+
+It comes with a standard development environment (gcc, python, etc).
+To see what's available:
+
+  $ flatpak run --command=sh com.visualstudio.code
+  $ ls /usr/bin (shared runtime)
+  $ ls /app/bin (bundled with this flatpak)
+
+To get support for additional languages, you have to install SDK extensions, e.g.
+
+  $ flatpak install flathub org.freedesktop.Sdk.Extension.dotnet
+
+to install the .NET Core SDK.
+
+You can use
+
+  $ flatpak search <TEXT>
+
+to find others.
