  AIS is a format used to package an image which is to be copied to
  the memory to be run. The format consists of a series of commands
  which are parsed and executed by the RBL(primary boot loader) to get
  the image copied to the memory, and then jump to the image's entry
  point(also specified as part of the format). I will add more info on
  this in the document, as you suggest.

  Will add this to the readme.
