 **Look at your Tessel!** The blue and green LEDs on your Tessel's LED panel should blink back and forth.
 
 **Bonus:** mess with the code to make the LEDs blink in sync.
+
+**Extra bonus:** what if you want to save blinky to your Tessel? There's a command for that! Try `t2 push index.js`, then unplug your Tessel and plug it back in again. Wait for it to boot up, then... lights will blink! Tired of the blinking lights? `t2 erase` will clear the saved code. Learn more `t2` commands by running `t2 -h` or looking at the [T2 CLI docs](https://tessel.io/docs/cli).

+Tessel's two module ports are not just for modules– they can also be used as flexible, simply [addressable GPIO](//tessel.io/docs/hardwareAPI) (general purpose input/output) pins.
+
+What does that mean? It means you're not limited to Tessel's ten-pin modules. In theory, you can connect nearly any electronic device or sensor to Tessel!

+
+For an experience nearly as easy as Tessel's ten-pin module experience, take a look at the [Community Modules](https://tessel.io/modules#third-party).
+
+These are hardware components for which members of the community have created npm libraries, documentation, and wiring information.
+
+For example:

+To see more community-created modules (or to add one you've made!) go to [tessel.io/modules](https://tessel.io/modules#third-party).
+
+_Note: we're still building out Tessel 2's firmware, so you might hit some bugs trying to use community modules. If you do, please report them! We're collecting status reports on community modules [here](https://github.com/tessel/hardware-modules/issues/5)._
+
+### Making your own Modules
+
+If no one has made the module you want yet, you can be the first! There are a lot of cool components on [SparkFun](//sparkfun.com) and [Adafruit](//adafruit.com) that are fairly easy to connect to Tessel.
+
+In case you've never built anything with hardware before, we've put up an introduction at [tessel.io/diy](//tessel.io/diy) that should get you up and running.
+
+Share what you've made, and if you need help, [just ask](https://forums.tessel.io/c/community-modules). Happy inventing!
