Here is how i build handmade using sublime text 3, which doesn't use a startup script. It's a bit more minimal than the other instruction, and you can build anywhere inside 'handmade' folder.
- unzip and copy attached build script 'handmade.sublime-build' to 'C:\Users\[user]\AppData\Roaming\Sublime Text 3\Packages\User'
- rename root folder to 'handmade'
do each time you open cmd:
- run 'misc/shell.bat'
- run 'subl .' in 'handmade' folder or just 'subl' if already open
- select 'Tools->Build System->handmade' (only first time you open project in subl)
- press 'ctrl b' to build
