Nice PR, thanks! Only one thing is, is there an easy way that we can add at the end to show that it really worked? Would be nice to add something like this if there is an easy way, if not I would leave it like it is.

After evaluation from me, I don't think I am a good person to write this part of documentation, as it is better done by somebody actually using the Kyma and the KymaInstanceMapping solution. Without this knowledge, I cannot add much value to this guide 🙂.

Thanks a lot for the addition. Just a red box would be nice. Thx

Can we highlight the Instance Mapping field? It makes it simpler to directly see where they find the information.
