General ⇒ How to import .cls template into Overleaf

[RedDot]

Hi,
I need to import .cls template into Overleaf, can someone guide me through it, please? Thank you in advance.
The latex templates are taken from here:

Just upload ursi2020_template.tex and ursi2021.cls to Overleaf and use ursi2020_template.tex as your document file or start a new document file using (uploaded) class ursi2021.

BTW: There is a mistake in the example file. You should not use the center environment inside figure (or table), because it adds extra vertical space. Use the command \centering instead. And h as only option for figure would not work, because LaTeX extends it to ht. If the figure should not float, you should not use a figure environment. And you should reference figures or equations using \label and \ref instead of writing Fig. 1 or Eg. (1).

Hi,
Thank you for your reply, I can't manage to upload these files because it requires a zip format and if I do it, it gives me an error.

"it gives me an error" is not a sufficient nor even somehow useful problem description.

If you do not know, how to make a zip-archive you should ask this in a OS forum.

However, you could, e.g, try 7-Zip. There are several alternatives depending on the OS you are using.

And instead of uploading a zip file of the project, you can also generate a new project and upload single or multiple files into that new project using the uploader. Please see the Overleaf documentation for more information.
