-==== Gateway - testing changes without any real traffic ====
+==== Gateway - testing changes ====
+Options for testing
+  * Deploy to production - see what happens
+  * Deploy to staging - see what happens
+  * Setup an personal network (on your laptop, or maybe on the server)
+  * Connect the gateway to a "fake" xbee virtually, using a pty and another script
+  * Mock out the serial device completely in python
 It's not necessarily practical to have hardware to test with all of the time and often hardware might not be available anyways. Luckily, with software we can work around this.
+**Note: development for the gateway should generally be done in a linux-based environment.** The gateway code was primarily designed only for linux-based environments and may not run locally.
+You can make a "fake" xbee network using the following python script:
+<code>
+import os
+import errno
+import time
+def symlink_force(target, link_name):
+    try:
+        os.symlink(target, link_name)
+    except OSError as e:
+        if e.errno == errno.EEXIST:
+            os.remove(link_name)
+            os.symlink(target, link_name)
+        else:
+            raise e
