This question already has an answer here:
For example, if someone asks this question:
I'm getting an error doing X. Why?
A possible answer could be:
You need to do Y to avoid getting this error.
If Y is a technique or tool and if Y has a tag, should I edit the question to add the y tag? It seems correct because specialists in y will be able to find the question and add more useful information.
However, I can see two issues:
My PC is freezing. What should I do?
You need to run an anti-virus to remove malwares.
Your PC may be overheated. Check if your fan is working correctly.
- If the question is marked with y, the OP will look a bit dumb for asking something that is quite obvious if you see the tag.
What series is it?
This is "Game of Thrones".
Adding a game-of-thrones tag would make the OP to look dumb.
Another example for this would be:
How can I securely store an user password?
You should hash the password before storing it.
In this case, should I add the hash tag?
So, how should I proceed? Is there a generic guidance?
