  This manual describes how to use the MatCHig code for matching the charged
Higgs boson production processes gg->tbH+/- and gb->tH+/-. A negative term,
correcting for the double-counting between these processes, is implemented as
an external process to PYTHIA, allowing the Monte Carlo generation of matched
events. Results from the matching were published in JHEP 0412, 050. The code
can be downloaded from http://www.isv.uu.se/thep/MC/matchig/ .
