 \section{Usage}
+\subsection{Basic usage}
 This package provides a single environnment, named {\ttfamily chordbar}, that has 2 mandatory arguments.
 The first argument is the number of bars, and the second is the pattern name.
 The latter one can be empty.
 Inside this environment, you can use several commands, the most basic one is 
 \verb|\chordf| (for "Chord Full bar") that has as unique argument the chord name.
-This argument will just be printed out "as is", usually something like "Cm7", Db9, FMaj7", etc.

+\subsection{Long parts on same chord}
+In some songs, you often have several bars on the same chord, say as an introduction or a bridge between two parts.
+Instead of filling a whole chordbars environment, a command is provided that will simply render the desired number of bars with the initial chord noted in first bar.
+
+For example, if you need a 8 bar intro on Gm7 chord, you can do this:
+\begin{lstlisting}
+\chordline{C#m7}{8}{Intro}
+\end{lstlisting}
+
+that will be rendered as this:
+
+\chordline{C#m7}{8}{Intro}
+
+Of course, the part and bar count will take this into account.
+Please note that this will always be a single line, so it is limited to standard situations (4 or 8 bars), it should not be used for longer parts.
+
+\subsection{Half bars}
+
+In some tunes, there can be a "special" bar inserted at one point that only has 2 beats instead of the regular 4-beat bars .
+This is handled with the special command {\btt \tbs addHalfBar} thats needs to be inserted in last position in a {\btt chordbar} environment.
+
+See for example this chord progression and its rendering:
+
+\lstinputlisting{listing_halfbar.lst}
+
+\resetchordbars
+\countbarsYes

+
+"Part 1" has an extra 2-beats bar added at the end, and the bar count is adjusted to take this into account.
+So "Part 2" starts at bar 6.
+
+\subsection{Song title}

+The package provides a {\btt \tbs songtitle} command that will format nicely the data given in the preamble with the classical 
+{\btt \tbs title} and {\btt \tbs author} commands.
