A step by step installing Tutorial for Magic Lantern 0.2 RC1 on the Canon EOS 550D / Rebel t2i using Windows.
If you don't know about the project already check it out at magiclantern.wikia.com
We are going through the whole process of updating the Canon firmware, making the card bootable, flashing the ml-firmware, and installing Magic Lantern in the end.
In case you want to stop using the ML Firmware, be sure to reverse the card from being "bootable" to "non bootable" with EOScard before inserting into your cam.
