+It is possible to relocate the toolchain, this allows to distribute
+the toolchain to other developers to build applications for your
+target. To achieve this:
+* run +make sdk+, which prepares the toolchain to be relocatable;
+* tarball the contents of the +output/host+ directory;
+* distribute the resulting tarball.
+Once the toolchain is installed to the new location, the user must run
+the script to make sure all paths are updated with
+the new location.
-It is also possible to generate the Buildroot toolchain in a directory
-other than +output/host+ by using the +Build options -> Host dir+
-option. This could be useful if the toolchain must be shared with
-other users.
