Some of the Guides are in Beta. This means that I was not yet able to source and/or verify some specific of the specific facts contained in the Guide, and that I therefore had to make some assumptions. I will usually point out where exactly this is the case.
Whether or not a Guide is labelled Beta does not really make a difference. In ei-ther case, the Disclaimer and use-your-head-policy apply – just a bit more so on the Beta Guides than on the more settled ones.
