+#### MSRV
+
+`thor-devkit` promises to maintain a reasonable MSRV policy. MSRV will not be
+bumped unless necessary, and such MSRV bumps will only happen in minor or major
+releases as soon as the first non-beta release goes live. The required version
+will never be newer than 6 months.
+
+Currently it requires rust `1.69.0` or higher to build.
