Any specific questions?  About things you didn't understand when
reading?

The basics are simple: You make a variable buffer local in the current
buffer with `make-local-variable'.  Then setting the variable whenever
that buffer is current sets the buffer local binding (in that buffer) of
this variable.  Evaluation of a variable results in the buffer local
value when there is one, else in the global binding.  `default-value' to
return the global binding of a variable regardless of buffer-local
bindings.

See also `setq-local' which makes a variable buffer local in the current
buffer an sets the value at the same time.
