Templates give you a ready-made starting point: the document class, preamble, and a sensible structure, so you write content instead of assembling boilerplate.
Start from a template
From the templates gallery you can create a new project pre-configured for a target — a conference format, a thesis layout, a preprint, or a CV. First-party starter templates include IEEE conference, APS RevTeX, a PhD thesis, an academic CV, and an arXiv preprint, each with a compilable main.tex and a bibliography where it cites.
The marketplace
Beyond the built-in set, the template marketplace hosts community templates. Free templates are one click to use; paid templates are available for purchase, with the author credited. Everything you use lands as a normal project you can edit freely.
Publish your own
If you have built a project worth reusing — a lab report format, a grant layout — you can publish it as a template for others. Free templates are open to everyone; priced templates go through the creator flow so authors are paid for what they share.
Note: A template is just a project. Once you create from one, its class files and
.bibare yours to change — there is no hidden link back to the original.
