0.5 installs the exact same way as 0.0. If you are updating from 0.0, you can simply download the 0.5 file, then reboot into clockworkmod. Clear dalvik and cache, then install 0.5 from the zip you downloaded.
or you can start from scratch by running the uninstaller and redoing the steps.
this update includes the charging/systemui fix, so no need to use that if you are starting fresh.
I will update the instructions fully later tonight.
