   Format: MarkdownItexadded the statement that [[categories with finite products are cosifted]] ([here](https://ncatlab.org/nlab/show/sifted+colimit#CategoriesWithFiniteProductsAreCosifted)). Since this is referenced or used in a few other entries, I will give the statement and its proof a stand-alone entry now... <a href="https://ncatlab.org/nlab/revision/diff/sifted+colimit/12">diff</a>, <a href="https://ncatlab.org/nlab/revision/sifted+colimit/12">v12</a>, <a href="https://ncatlab.org/nlab/show/sifted+colimit">current</a>

   added the statement that categories with finite products are cosifted (here). Since this is referenced or used in a few other entries, I will give the statement and its proof a stand-alone entry now…
