 .. _`support for Python 3`: https://www.mercurial-scm.org/wiki/Python3
 
+Python 2 Support
+================
+
+Python 2 is supported by evolve. However, Mercurial 6.2 release dropped support
+for it, so evolve can work on Python 2 only on earlier versions.
+
+Debian packages that are built using Heptapod CI only install files for Python
+3, because they target current Debian stable.
