 scheme.forth.jl
 ---------------
 
-A hobby scheme implementation for FORTH 83. Specifically it is targeted at my
-own [forth.jl](http://github.com/tgvaughan/forth.jl) which is an implementation
-of FORTH on top of [Julia](http://www.julialang.org), hence the name.  However
-it does not rely on anything but standard FORTH 83 words.
+A hobby Scheme interpreter for FORTH 83. Specifically it is targeted at
+[forth.jl](http://github.com/tgvaughan/forth.jl) which is an implementation of
+FORTH on top of [Julia](http://www.julialang.org), hence the name.  It began
+life as a fairly direct port of Peter Micheaux's [Bootstrap
+Scheme](https://github.com/petermichaux/bootstrap-scheme) (as described in
+[this wonderful series of blog
+posts](http://peter.michaux.ca/articles/scheme-from-scratch-introduction)) from
+C to forth, but also includes a basic mark-sweep garbage collector, quasiquotation,
+and a very basic (non-hygenic) macro system.
+
+In future, I plan to also implement a more complete numerical tower to bring it closer to
+[R5RS](http://www.schemers.org/Documents/Standards/R5RS/).
+
+The goal is for the interpreter to be complete enough to be used to complete
+the majority of the exercises found in [SICP](http://sarabander.github.io/sicp/).
