Deployment process and commands?

[Ram]

Hi,

We deployed our first version of source code our dJango application into our development hosting server using 'git clone ...' command. Now we need to deploy or integrate next version of developed code, for which we would like to know commands and process to achieve the following.

1. Do we need to use 'git pull ...' for every new integration inside the virtual environment project where we cloned our first version of source code?

2. How to name each integration build or version string and what would be ideal format?

3. How to create changelog for each integration?

We would like to implement CI in our current product development. Could someone point me simple instructions or document that will help me to achieve the above.

Thanks,

~Ram
