+This repo is for the overall Lisp environment for Medley / Interlisp-D / Xerox Common Lisp.
 A sub-project is Interlisp/maiko which is the emulator of the Lisp virtual machine. 
-The files that should be checked in are at 
-https://www.icloud.com/iclouddrive/0WoL_hL2vH5xA2QTbPZ96g7rA#medley 
 
-pending resolution of https://github.com/Interlisp/medley/issues/17
+NOTES:
+
+At the moment we're still in the process of sorting out what we have and insuring we start with a solid base.
+
+File Names and Extensions: Most Interlisp source file names are UPPERCASE and Interlisp didn't use file extensions for its source directories.
+(note that any .TEDIT or .TXT file is probably documentation for the package of same name, at least in the library, internal/library, lispusers)
+The current repo has only Lisp sources with .LCOM and .DFASL in .gitignore. But many files don't compile in a vanilla lisp.sysout ;
+there is a file of external declarations (EXPORTS.ALL) and something called ABC that has some other record package declarations.
+
+
+
+
+a) get the binaries lde ldex for your machine (darwin.x86_64 (mac) linux.x86_64 (linux, use VirtualBox for windows, linux.arm??)
+b) 'run-medley -xfull' should run the xfull sysout in the 'loadups' directory
+
+Each directory should have a README.md, but briefly
+docs -- Documentation files (either PDFs or online help)
+fonts -- raster fonts in various resolutions for display, postscript, interpress, press formats)
+initfiles -- should have any necessary setup of directories Lisp should look in for load
+internal -- These _were_ internal to Venue
+library  -- packages that were supported (30 years ago)
+lispusers -- packages that were only half supported (ditto)
+loadups   -- has sysouts and other builds
+sources   -- sources for Interlisp and Common Lisp implementations)
+
+Note that Interlisp and Common Lisp functions have different compilers, but it's all freely intermixed.
