I am looking for some guidance regarding the setup/source code/upgrade effort related to Umbraco. I have a web site setup in the following directory (this is where i have local iis pointing) D:_Projects\Umbraco\UmbracoSetup\UmbracoSetup < this directory contains for example AppCode, AppData, AppPlugins, Bin, ... ,umbraco, umbracoclient, ..., , web.config

The above site works fine, and i am quite happy with Umbraco. Now I noticed a new release 7.2.5 is available.

I also have a directory D:_Projects\Umbraco\Source\Umbraco-CMS this directory contains .git,build,src,tools I had originally opened src and the sln with vs.net 2013 and tried to build and realized that was not working. I navigated to build and ran build.bat which appears to output all build files to D:_Projects\Umbraco\Source\Umbraco-CMS\build. Within this directory i see _buildOutput which has the following directories bin,configs,webapp,webpi

Ok so this leaves me with a few questions how does the _buildoutput contents relate to my running site at D:_Projects\Umbraco\UmbracoSetup\UmbracoSetup ?

If i wanted to upgrade from 7.2.4 to 7.2.5 how would I go about doing this? (is it as easy as sync-ing some directories?)

If i was going to create a new project/module with umbraco would I do it within the src directory

I noticed after i ran build.bat i could go back to the sln within the src directory and build the solution. Is it really just running the build/build.bat ? (I am not quite sure how a build of sln gets to running the build.bat)
