Installing ezinit can be fairly straight forward like, but then again nothing about life is ideal or fairly straight forward; that's why we have wikis (j/k).
1. First, download the zip file.
2. Find where you downloaded the zip file :P.
3. Extract ezinit into your folder of choice.
1. (I keep mine in my home folder, and since I use Linux, I commonly think of it as the '~/' folder. At any rate it's the directory that the terminal sends you to when you just type in 'cd' and press enter.)
4. Make sure that you're in the same folder where ezinit was extracted to and type 'sudo chmod <YOURUSERNAME> ezinit.sh'
5. Then go into your home directory, if you're not already there, and type `echo "alias ezinit='<PATHTOEZINIT>/ezinit.sh'" >> .bashrc`
6. Then go ahead and edit ezinit.sh to your hearts content and I'll have to add more comments to it so that people will know what to edit and what not to edit, unless they really want to edit stuff.
