Hello!
I am so happy that you are interested in this project!
Of course you can use all the resources available on Thor! You can certainly use screenshots from the interactive manual 🙂
The great thing about Open Source projects is precisely that we can develop a project together, supporting each other and sharing the progress!
That said, if when you create that assembly guide you can share it with this community, I’m sure it will be useful to someone 😀
Don’t hesitate to ask if you have any questions!
Best regards,
Ángel
