You can find explanations in the documentation

HOME_OFFSET =                    0.0             - the amount you want to
table to move from the homed zero position after the index pulse is found
and the encoder position has been set to zero. You don't necessarily need
to know exactly how this works prior to homing. Just leave zero, home the
machine and see what happens.
Then put a value in, home the machine and see what happens.
You can then adjust what value you put in to achieve your desired home
position.

HOME_SEARCH_VEL =                20.0     - the speed to move the axis when
you are homing (+ or - determine direction)

HOME_LATCH_VEL =                 20.0       -  the speed to move the axis
after hitting the home (or limit) switch while searching for the index
pulse (again + or - determines direction)

HOME_USE_INDEX =                 NO        - YES here tells the controller
to read the encoder index pulse connection. The encoder board then sets the
position to zero upon seeing (finding) the index pulse.

HOME_IGNORE_LIMITS =             NO    - YES here tells the control to
ignore the axis limit switches while homing. This allow the limit switch to
also be used as a home switch to start the search for the index pulse.

HOME_SEQUENCE = 1                           - check the manual for using
this
HOME_IS_SHARED = 1                           - check the manual for using
this

These parameters are found in the ini file
