LeChatelier's Principle states that if the pressure, temperature, or concentration of a chemical species is changed in a reversible chemical reaction, then the equilibrium will shift to compensate for the change accordingly.  In other words, if a particular chemical is added to the reaction, the equilibrium will shift in the opposite direction to consume the added material.  So in your example above, if you want to shift the equilibrium to the left, you need to add some additional CO or H2 (products).  If you want to shift the equilibrium to the right, you need to add some more CH4 or H2O (reactants).
