CCL: Manual Work out

Dear Folks,

I am very new to computational chemistry,
and i am interested to know, how the programme works.

For example, consider a simple H2 molecule.

I wish to work this geometry optimization
in a blackboard and compare my
result with the computer obtained results.

In this regard, i wanted to ask you if any one of you
have done this as a tutorial, and so, would you mind
sharing it with me please.

Best regards,

Dr. Sanjay Bharathwaj Kumar,
