@vaeng I took a first stab at writing the installation instructions for Boost on Windows. Could you take a look?

Thanks a lot for your effort improving documentation. Let's see if we can make it even easier for students!

Thank you for the guide.

Apart from the comments from Shane, please also see the exercism formatting guidelines for markdown documents.

Especially the part about links and keeping each sentence to its own line. It helps a lot with maintaining and tracking in git.

Thank you both, that is really great feedback!

I will try to see if I can make it work the way @ahans suggests. I prefer using something under %USERPROFILE% to install Boost, maybe just %USERPROFILE%\Libs.

Alternatively there is still the option to use a package manager like vcpkg which would allow one to just put boost-date-time in the project folder. I have not tried that route yet, but could if you think it is worth the try.

@vaeng The existing INSTALLATION.md does not follow the rules you link to, especially with regards to reference links. If I am going to adhere to the guidelines, I think it is best the entire document does. Would you want me to go over the entire document and make it rules compliant? If so would you want me to do that in this PR or in a separate PR? The latter option makes the most sense to me since we then separate the formatting changes to the existing document from the information I intend to add.

[vaeng]

I think a separate PR to format the rest of the document is the cleanest solution, if your additions are already compliant.

@vaeng, @ahans I did as you suggested. Things should be (much) better now.
