 OpenEmbedded/Yocto layer for the Sourcery G++ toolchain
 =======================================================
 
+Usage & Instructions
+--------------------
+
+- Ensure that you have the Sourcery G++ toolchain installed.
+- If it's an ia32 toolchain, make sure you did *not* let it modify your PATH,
+  and if you did, remove it.
+
+  This is necessary because the ia32 Sourcery G++ toolchain
+  shipped non-prefixed binaries (e.g. `gcc` rather than `i586-none-linux-gcc`), which
+  means bitbake would be unable to run the host's gcc directly anymore.
+- Add the meta-sourcery layer to your `BBLAYERS` in `conf/bblayers.conf`. Please make
+  certain that it is listed before the `meta` layer, as this ensures meta-sourcery gets
+  priority over meta.
+- Set `EXTERNAL_TOOLCHAIN = "/path/to/your/sourcery-g++-install"` in `conf/local.conf`.
