# Managing Font Map Files

Information about outline fonts is stored in a file by the name of `psfonts.map`. This file is normally created automatically. It can be manually created by running `miktex fontmaps configure` (see miktex 1).

psfonts.map creating

`psfonts.map` depends on the file `updmap.cfg`. This configuration file contains declarative instructions, which will be used to build `psfonts.map`.

The contents of `psfonts.map` should never be edited directly. Your modifications get lost when you install new packages.

For example, follow these steps if you want to add an entry for the font map file `xyz.map`:

- Run `initexmf --edit-config-file updmap`.

- Insert the following line at the end of the file:

      Map xyz.map

- Save the file and close the editor.

- Run `miktex fontmaps configure` to rebuild the font map files.
