I know there are lots of posts about this issue but all of the different posts confuse me so I need someone to focus me on this.
Until now our team didn't use any source control, we had just one project folder which we sometimes duplicated to work in parallel but it wasn't east to merge.

Next year we plan on programming more in parallel so we want to use a source control program.
I have no experience with this so I need detailed help on which option is the best and how to set it up.
If possible we prefer that the main repository will be on a local machine connected through LAN so we won't be dependent on regular internet connection.

Thank you!
