+# 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:
The topic of drawing multiple-lines comes back from time to time. I am
also be in favor of having such interface beacuse it seems to be a basic use
case. Somebody was trying again to add it, few months ago, but I don't know
where it ended up.
I understand, these READMEs seems to be more serious. For me README is just
a way to communicate. If someone needs to know something and there are some
solutions, README would be the place.
Anyway, it should be enough for this PR then.
