+Renesas 32-bit SH4 SoC build environment setup
+==============================================
+
+In order to cross-compile U-Boot for SH3 32-bit target, it is necessary
+to install suitable toolchain. The toolchain is available in various
+distribution repositories as ``sh4-linux-gnu-*`` or similar package.
