+# Usage
+
+Import with `#include <lvgl/lvgl.h>`.
+
+Upstream example is present at `examples/lvgldemo`.
+
+LVGL can be used with framebuffer device. To find example boards with this
+preconfigured, search for `CONFIG_GRAPHICS_LVGL=y` in `defconfig` files.
+All of them have also `CONFIG_VIDEO_FB=y` present.
+
+As a second option, LVGL can talk to a display driver and explicitly draw line
by line.
+For this case, there is no preconfigured board present. Go to _Porting_ section
+of upstream documentation for more hints.
Review comment:
@v01d So there is some emulation layer that can be enabled? I don't see
explicit option here http://nuttx-config.nxtlabs.pl/#/?current=VIDEO_FB. Maybe
we should add information about this emulation and your custom solution to the
README to help people who want to use LVGL. Could you describe in three
sentences something that could be put into this README? Readmes are empty for
many of the apps. I am not sure why.
