CI: add libgit2 dependency

Added better explaination and footnote to avoid people oppening
issues/disscussion threads in Vivify instead of NoteWrapper. See

 ### Fields
 
-* `directory`: root directory containing all vaults
+* `directory`: Array of directories containing the vaults.
 * `render`: enable/disable Vivify rendering
 * `jumpToEndOfFileOnLaunch`: move cursor to end of file on open
-* `editor`: selected editor (must be supported)
+* `editor`: selected editor (must be supported). If not set, it defaults to `$EDITOR`.
 * `journalRegex`: regex used to detect journal files
 * `dateEntry`: format for journal entries (see `strftime`)
 * `newLineOnOpening`: add a newline when opening a note
 * `backup.enable`: enable automatic backups using `rsync`
-* `backup.directory`: destination directory for backups
+* `backup.directory`: backup's destination for each directory
 * `backup.interval`: backup frequency (`daily`, `weekly`, `monthly`, or integer)
 * `backup.rsyncArgs`: arguments passed to `rsync`
+* `git.enable`: enable git version control for backups
+* `git.name` and `git.email` are for the commits signature
+
+Note: 
+* Directories must end with `/`.
+* All directories used must exist.
+* Elements of `directory` and `backup.directory` must match exactly.  
+* Directories set in `directory` but not in `backup.directory` won't be backed up.
+* Directories set in `backup.directory` but not in `directory` will be ignored.
+* `journalRegex` must match if the file name ends with `.md` and if it doesn't.
+* It is recommended to keep `-q` or `--quiet` flag in `rsyncArgs` to avoid interference with `ncurses`.
+* If `rsync` fails, you will see it inside `ncurses`.
+* If you want the git backup but without rsync, you can leave `backup.directory` empty or map each directory to itself. When enabled, git will apply to all your vaults.
+* Each vault gets its own git repository that will be created the first time you select the vault with the option enabled.
