Most journals accept a PDF of your manuscript at initial submission and require you to submit your manuscript with source files at a later stage. However, some journals require a manuscript to be submitted in a specific template file. In these cases, the template is probably in LaTeX and in exceptional cases in CRC.

If a journal requires you to use a certain template for submission, you can find this in the journal's Guide for Authors. Consult your Guide for Authors from the journal homepage. To go to your journal's homepage, search for the journal using the search box under 'Find by journal title' in the journal author's page.
