  CosmoMC is a Cosmological Monte Carlo package that explores parameter space,
finds the best-fit values, and makes contour plots for various observational
data. The present manual assists you with the installation steps and running of
CosmoMC. Also, we briefly explain Markov chains analysis and generating plots
and tables for the parameters. This guide is for everyone who is not familiar
with GNU/Linux and wants to install and run CosmoMC for the first time.
