Appeal procedure in civil court against order of lower court

I am a newly qualified lawyer and lost my first suit contested on behalf of defendant.  All evidences of plaintiff were proved wrong except email admission given under pressure by my client.  Unfortunately lower court judgement dismissed all my arguments stating if admission in writing is given, no other evidences of defendant that proves complaint is wrong matters.

Now, I want to prefer appeal against lower court judgement (Civil Court Senior Division, Pune).  Value of suite is Rs. 79000.  Can someone please help me with documentation requirement to file appeal against the said order?

Thanks in advance.
