[Elecraft] KX3 Beta 1.36 Additional Instructions?

[Jim Sheldon]

The separate instructions mentioned in the below paragraph from the Beta 1.36 release notes don't seem to be available.  I've looked for them or a highlighted link to them somewhere but so far have been unsuccessful.  Anyone know where they are?
