-## Building
-
-To build an executable just run:
-
-    nim c joy.nim
-
-To build and immediately run an executable use:
-
-    nim c -r joy.nim
-
-To build a smaller binary do:
-
-    nim c -d:release joy.nim
-    strip --strip-debug joy.exe
-
-
 ## Dependencies
 
 - Nim functional programming library https://github.com/vegansk/nimfp
 - Pure Nim (i.e. not GMP) BigInts library https://github.com/def-/nim-bigints
 - ... 
 
+If you have `nimble` installed:
+
+    nimble install bigints nimfp 
+
+
+## Building
+
+To build an executable just run:
+
+    make
+
+This will copy the `implementations/defs.txt` file into the Nim project and
+compile the `joy` executable.

 ## TODOs:
 
-- link to other Thun sub-projects & info on Joy in general
 - ctrl-c should exit cleanly
 - graphics?
 - `words` and `help`?
 - How to integrate docs?
