 The Knot DNS Resolver depends on the development version of the Knot DNS library, and a reasonably recent version of `libuv`.
 Several dependencies may not be in the packages yet, the script pulls and installs all dependencies in a chroot.
 
+You can avoid rebuilding dependencies by specifying `BUILD_IGNORE` variable, see the [Dockerfile](scripts/Dockerfile)
+for example. Usually you only really need to rebuild `libknot`.
