+# Guix Scheme Containers and Environments
+
+Run Scheme implementations in Guix containers/environments, and package
+libraries for them.
+
+## Chibi Scheme
+
+Chibi is meant to be embedded and doesn't have a modifiable global
+library path of its own. Instead it uses a modified package definition
+of `chibi-scheme` with the module path `share/guix-chibi` (interpreted)
+and `lib/guix-chibi/` (shared objects).
+
+Packages of only Scheme code intended for use in Chibi should use the
+`chibi-scheme-build-system` build system, which will simply copy files
+to the appropriate directory. Code that contains shared objects (from
+`chibi-ffi`) should use `gnu-build-system` and copy the files in an
+input.
