Install apk onto Moto G first generation using apk file

[shinnen]

I have this phone, and some apps in the form of apks, that I would like to install on it, but there seems to be no why, that I can see, of doing it; there is no file manager. I seem to be able to transfer the apks to the phone, but they don't show up in the downloads folder, or anywhere else.
Any help is appreciated.

How did you download the files? Were they downloaded from Chrome or another browser?
