You can install node, npm, github, git-lfs and sublime text editor in one and can clone your repositories and install the node dependencies through the github feature. The goal is to make installing the development tools necessary to run many projects easy for designers.
Download as a zip file and extract to where you want to run it.
Go into the dev-tools directory and ctrl click or right click the app and select 'open'. You will be prompted to confirm opening the app since it is unsigned.
After the gui launches, you have the option to install dev depencies like node and sublime etc. If you don't have the dev tools, install them first. The install process may take awhile. You will be notified when it is completed.
Afterwards, you can enter your github credentials, select the repo you want, download it and automatically install the depencies you need to run it.
