Cd into the root directory of your project and type hg init. This merely creates the subdir .hg which is the repository. The current dir becomes the working dir of the project.

Add all files to the project by hg add and hg commit

Proposal: Have a central repository per project which is not worked on. For each subproblem to solve clone the central, work on the clone and push the modifications back to the central. More than one subproblem specific repostiories at the same time are possible and encouraged.

hg clone project project-subproblem # clone repository to get new working dir
cd project-subproblem
# make changes
hg commit
hg push ../project

Note, that after the push, the working dir in the central (project) are not modified, the parent (hg parent) is still the old revision. Use hg update in the central to mend this.

hg revert <file1> [<file2>]

Restores the files in the working directory to the state when they had been last commited. Much more options are posssible, see hg help resore Hgbook Wiki
