Author: nLab edit announcer Format: MarkdownItexMaybe trivial but the homotopies of homotopy equivalences should go from XxI to X and not XxI to Y and analogous the homotopy inverse. I am no expert so hopefully I did not have a mental breakdown or something :).

Author: Urs Format: MarkdownItexadded a remark ([here](https://ncatlab.org/nlab/show/Introduction+to+Homotopy+Theory#InCatOfFibrantObjectsProductPreservesEquivalences)) making more explicit that, in a category of fibrant objects, products preserve weak equivalences (which is used later on but was previously not referenced to the relevant lemma).
