This template lets you pick the publisher style in a settings.tex file: acm, ieee or llncs. The class files and bibliography styles for each are included (acmart, IEEEtran, and the splncs04 style), alongside a references.bib file. The sections to include are listed in settings in the order you want, and each lives in the sections folder. The sample has a title, three authors with two affiliations, an abstract, keywords, an introduction and a conclusion.
