Hi there, the first stop when learning about custom ROM's should be Google. I did a search for you to make sure the wiki was accessible, it was the fourth result for me. My search statement was simply "how to put cm on moto e"
Here is the link to the wiki:
https://wiki.cyanogenmod.org/w/Condor_Info
I would read through that, then do some searching on terms you may not understand. Another good resource is XDA, there you can find a lot of good info as well. Last, but certainly not least, you can post in the CM forum for that specific device to talk to other users.
