+# About
+
+This is a test application for the Seeed Studio Grove LED bar module [1].
+
+# Details
+
+This test application will initialize a Groove LED bar with the configuration
+as specified in the `grove_ledbar_params.h` file. To connect the LED bar with
+your board use the following pinout:
+
+- Pin GND is connected directly to GND.
+- Pin VCC is connected directly to VCC +3.3V, or 5V if your board allows that.
+- Pin DCKI is the clock pin and is connected to a free GPIO
+- Pin DI is the data pin and is connected to a free GPIO, too
+
+for the 2 latter pins note the port and pin number and adapt the Makefile
+accordingly.
+
+The test application will light up the LED bar several times, running from 0%
+up to 100% and down to 0% again.
