There's one problem with this: The Tour is *designed* for completely new users. Yes, users from other sites can also read it, but it's mainly to tell **completely new users how the Stack Exchange model works**. It tells them:

- how to vote
- what tags are
- what badges are
- how answers are shown
- a *brief* section on what should be asked/what shouldn't

I say brief, because what you want is on the **/help/on-topic** part of *every* site. You can access that with the url **http://sitename.com/help/on-topic**, or just go to the help center (eg. [MSE](http://meta.stackexchange.com/help)) with the URL **http://sitename.com/help**.

Examples:

[Super User](http://superuser.com/help/on-topic):

> Super User is for computer enthusiasts and power users. If you have a
> question about …
>

> - computer software, or
> - personal and home computer networking
> 
> and it is not about …
> 
> - programming and software development,
> - video games or consoles,
> - websites or web services like Facebook, Twitter, and WordPress,
> - electronic devices, media players, cell phones or smart phones, except insofar as they interface with your computer,
> - issues specific to corporate IT support and networks,
> - asking for a product, service or learning material recommendation,
> 
> … then you’re in the right place to ask your question!

[Stack Overflow](http://stackoverflow.com/help/on-topic):

> Stack Overflow is for professional and enthusiast programmers, people
> who write code because they love it. We feel the best Stack Overflow
> questions have a bit of source code in them, but if your question
> generally covers…
> 
> - a specific programming problem, or
> - a software algorithm, or
> - software tools commonly used by programmers; and is
> - a practical, answerable problem that is unique to software development … then you’re in the right place to ask your question!
