but its very hard to download right now lol (wonder why)
here is a link to the downloads make sure your downloading 2.8 and not the 2.79 release
https://builder.blender.org/download/site is getting bombarded .. be patient..
edit : err I guess i should say how to load the blender. There is no installer at this point. Just unzip the file and put it wherever you want and open the folder and look for the blender Icon and click it to start the software.
