+# The Easy Way
+
+If you can find firmware someone else has made that does what you want, that
+is the easiest way to customize your ErgoDox.  It requires no programming
+experience or the setup of a build environment.
+
+Quickstart:
+
+  - Find and download an [existing firmware](#other-firmware-options)
+
+  - Then flash the firmware to your [ErgoDox Ez](#ergodox-ez)
+    or [ErgoDox Infinity](#ergodox-infinity)

+### Infinity Master/Two Halves
+
+The Infinity is two completely independent keyboards, that can connect together.
+You have a few options in how you flash the firmware:
+
+- Flash the left half, rebuild the firmware with "MASTER=right" and then flash
+  the right half.  This allows you to plug in either half directly to the
+  computer and is what the above instructions do.
+
+- Flash the left half, then flash the same firmware on the right.  This only
+  works when the left half is plugged directly to the computer and the keymap
+  is mirrored.  It saves the small extra step of rebuilding with
+  "MASTER=right".
+
+- The same as the previous one but with "MASTER=right" when you build the
+  firmware, then flash the same firmware to both halves.  You just have to
+  directly connect the right half to the computer.
+
+- For minor changes such as changing only the keymap without having updated
+  any part of the firmware code itself, you can program only the MASTER half.
+  It is safest to program both halves though.

 # Contributing your keymap
 
 The QMK firmware is open-source, so it would be wonderful to have your contribution! Within a very short time after launching we already amassed dozens of user-contributed keymaps, with all sorts of creative improvements and tweaks. This is very valuable for people who aren't comfortable coding, but do want to customize their ErgoDox. To make it easy for these people to use your layout, I recommend submitting your PR in the following format.
