 Currently none are fully supported.\
 In future versions it will be possible to request the current state of supported modules via the gNMI Capabilities command.

+### Devcontainer - local
+
+For this method you only need `docker` and `vscode` with the plugin `Dev Containers` from Microsoft installed.
+After you installed the required tools, you can simply open the folder in the dev container.
+Either you click on `Open in Container` if a pop-up appears on the bottom right, or by selecting `Open in Container` after clicking on `Remote Explorer` in the left bar in VSCode. Please note: depending on your internet connection and the performance of the device, the initial creation of the container can take several minuts or longer! Furthermore the initial git discovery of every submodule in this repo (if installed) can also take some minutes.
+
+The devcontainer has everything you need in it (even relevant VSCode plugins), so you should not need anything more.
+Please keep in mind that this setup is not tested thoroughly!
