How to download minecraft on my android phone without going to android market?

Under applications settings there's this setting that says something like "Allow Non-Market installations" or something in that manner, you need to enable that or make sure you enable that, search for minecraft pocket edition apk, and install it, from the phone, or download it to a computer, transfer the apk file to the phone, make sure you have a File Manager and then install it that way. Sorry if I confuse you.
