How to make a web project available through git?

I have a simple web project that I made on the top of http://ift.tt/XWSVlK.

This generates a great project environment with bower and grunt support, where the .js, .html, and .css files are positioned inside a folder called "app" (similar structure to http://ift.tt/1QcdfUx).

Everything is working great in localhost. I run a command code (grunt serve) and it starts to run into the browser. However, I am not being able to make the same be available online.

It is important to highlight that I don`t want to "publish it officially", I just want to be able to send a link to my friends, so they could try it (as users would) and give me feedback on it.

I am not talking about sharing the code, no. I just want to make it available as it would be for users once it is done.

For example, if I go to http://ift.tt/1Nd8XBT, I can try what the repository http://ift.tt/1QcdfUx has.

Also, the standard page publication available by git seems not to work for this structure.

Any clue about how could I do that?

I am just an enthusiast that don`t have much experience in making web projects available.

Thanks in advance, Roger.
