Nvim setup instructions for the layman?

Question

I'm trying to install vim and nvim as a replacement for Notational Velocity. I recently migrated to Ubuntu (14.04) and I'm very new to how everything works. The instructions for installing nvim are kind of elliptic and not entirely clear to me as a beginner. I manage to get it running if I enter vim and then type :Nvim inside the directory where I store my .txt notes. However, the notes aren't visible in nvim and here's where I run into trouble. As a beginner I simply do not understand the instructions regarding PATH and :python that are given on the installation page. I've tried (successfully, I think) to install xapian as well (after having installed vim) but nothing changed. That is, I cannot specify a PATH for my nvim and I cannot get the nvim script to work as a command anywhere in the terminal.

More consequentially, when I type

:python nvimdb.rebuild_database()

inside vim, I get:

Traceback (most recent call last):
File "", line 1, in
NameError: name 'nvimdb' is not defined

What I would like to ask for are step by step instructions for making nvim work with an existing library of .txt notes targeted at the vim and linux novice.

The program looks great and appears to be exactly what I need for my note taking needs, and I would really appreciate your help! Thank you so much.

I believe this is probably because you haven't installed the xapian library as that is a required mentioned by nvim. You need to install the package xapian-core I believe, you can do that in ubuntu with something like this : sudo apt-get install xapian-core
