+# DuckTag
+
+## Targets
+
+Nerves applications produce images for hardware targets based on the
+`MIX_TARGET` environment variable. If `MIX_TARGET` is unset, `mix` builds an
+image that runs on the host (e.g., your laptop). This is useful for executing
+logic tests, running utilities, and debugging. Other targets are represented by
+a short name like `rpi3` that maps to a Nerves system image for that platform.
+All of this logic is in the generated `mix.exs` and may be customized. For more
+information about targets see:
+
+https://hexdocs.pm/nerves/targets.html#content
+
+## Getting Started
+
+To start your Nerves app:
+  * `export MIX_TARGET=my_target` or prefix every command with
+    `MIX_TARGET=my_target`. For example, `MIX_TARGET=rpi3`
+  * Install dependencies with `mix deps.get`
+  * Create firmware with `mix firmware`
+  * Burn to an SD card with `mix firmware.burn`
+
+## Learn more
