Initial setup on wiki

[dsm1212]

As someone just setting up everything from scratch the lack of specificity in the wiki was agonizing. Here are a couple of key things to know if you could add them:

To work with Calibre this container requires a separate installation of Calibre. That separate Calibre installation needs to map its library to a location where this LazyLibrarian container can find it. Both containers should bind the /books volume to the same folder. You must install Calibre and initialize the library into this folder before installing and configuring LazyLibrarian. Otherwise your /books folder may not be empty and then you cannot move your Calibre library there. In Calibre when you create or move your library it must be to /books, not /books/Calibre Library or this LazyLibrarian container won't find it. When Calibre is configured correctly you will find a metadata.db file in the /books folder, then you can install this LazyLibrarian+Calibre container.
