In English, there is the construction how to + [infinitive], e.g. in:
I don't know how to do such and such thing.
How to this and that is a different matter.
How to win friends and influence people.
Is there some equivalent in German? Is wie zu valid?
Nowadays the German language makes heavy use of the English "How to". There is not a 1:1 equivalent using "wie", but possible alternatives are:
Wie man xyz macht (How one does xyz)
Wie man Pizza zubereitet (How one cooks pizza)
Wie man richtig eine Krawatte bindet (How one correctly ties a tie)
I.e. a 3rd person variant ("how one/ how you").
Other possibilities:
Anleitung zum Kochen
Anleitung zum Krawattebinden
There is no direct equivalent of this English construction, so you will have to add a subject. E.g.
Ich weiß nicht, wie man das macht.
or, more personally,
Ich weiß nicht, wie ich das machen soll.
There's a famous series of DIY books (or "How-Tos") in Germany published since 1962 as as repair manuals for all sorts of cars titled
Jetzt helfe ich mir selbst: VW Käfer [e.g.]
which basically translates into "How to repair a Volkswagen Beetle".
The GDR hat a similar set of books called "Wie helfe ich mir selbst" on the famous Trabant.
If you want to refer to something comparable, using this title would be sufficient.
