Likely you will have to do it manually, which means you will have to
understand Chapter 5 of the manual and the proper parameterization
protocol for your molecules under the chosen force field.

Some web servers exist for such purposes, depending on the force field
you want to use.  Otherwise consult the following page and be prepared
for a significant time investment:

Hm, that page is slightly outdated. You want to google for
antechamber / gaff /amber
respectively
charmm / cgenff
