CosmoMC Installation and Running Guidelines

CosmoMC is a Fortran 95 Markov-Chain Monte-Carlo (MCMC) engine to explore the cosmological parameter space, plus a Python suite for plotting and presenting results. This document describes the installation of the CosmoMC on a Linux system. It is written for those who want to use it in their scientific research but without much training on Linux and the program. Besides a step-by-step installation guide, we also give a brief introduction of how to run the program on both a desktop and a cluster. We share our way to generate the plots that are commonly used in the cosmological references. For more information, one can refer to the CosmoCoffee forum or contact the authors of this document. Questions and comments would be much appreciated.
