+## Environment
+
+During development it is a good idea to clone the `cyclone-bootstrap` repository as well as the `cyclone` one. Place both directories in the same parent directory and you can use `sync.sh` to copy individual compiled files to `cyclone-bootstrap`, or `make bootstrap` to copy everything.

 ## Building
 
 Please use cyclone-bootstrap if you are installing Cyclone on a machine for the first time. Otherwise, if you already have a copy of Cyclone installed you can build from Scheme source.

+## Testing a Build
+
+`make test` may be used to perform basic testing. 
+
+To make sure everything works, install a modified copy of Cyclone and run the following to rebuild the libraries, compiler, interpreter, and examples from source:
+
+    $ make clean
+    $ make
+    $ make test
+    $ make bootstrap
+
+This confirms that the compiler - with any changes - can still be built from source, and syncs any changes up to `cyclone-bootstrap`. Before checking in a set of changes or releasing a build it is also a good idea to do a rebuild of the bootstrap repo also, to make sure it still works.
