+* Generating PDFs
+A PDF can be generated using the following command:
+#+begin_src bash
+guix shell -m manifest.scm -- make
+#+end_src
+Assuming that [[https://guix.gnu.org/][GNU Guix]] is installed, this command will handle downloading all
+dependencies, generating a pdf, and cleaning up temporary files.
