No that much.
I have started a Wiki ... still very limited ... I am a programmer with limited doc-skills.
http://wiki.freepascal.org/fpcupdeluxe
However, the main purpose of fpcupdeluxe is to make the install of FPC and Lazarus as easy as possible. Without reading (of having to read) the manual.
Short install manual:
Start fpcupdeluxe.
Choose an install-directory (or leave default).
Press one of the speed-buttons to perform an install.
Use the generated link to start the installed Lazarus version.
Short crosscompiler manual (after above install):
Choose a CPU and an
OS.
Press install crosscompiler.
Use.
I hope you will succeed.
