The above guide is good, but it is not very clear and unambiguous. It is not a step by step guide.

Can someone explain some things:

1. It says "Download ThomasV's PGP Key" and nothing else. Does this mean Download ThomasV's signature from the Electrum website? Or are they separate things?

2. The guide does not cover some important points. For example, after installing GNU Privacy Guide, I found some important points on this video suggesting that you ask "show more details" rather than just click on Yes.

But this is not included in the above guide. If you are doing such things for the first time, how are you supposed to know? But then, if you suffer a problem, everyone will say: Why did you not do this/that? But how are you supposed to know if such things are not included in the guide and you are doing this for the first time?

Is there maybe another guide that is really step by step and takes you through every single step and does not leave anything out? On a website or maybe online video?

Thanks.
