+#### Hello world
+
+```Lua
+local ctr = require("ctr")
+local gfx = require("ctr.gfx")
+local hid = require("ctr.hid")
+
+while ctr.run() do
+	hid.read()
+	local keys = hid.keys()
+	if keys.held.start then break end
+
+	gfx.start(gfx.TOP)
+		gfx.text(2, 2, "Hello, world !")
+	gfx.stop()
+
+	gfx.render()
+end
+```
+This script will print "Hello, world !" on the top screen, and will exit if the user presses Start.
+This is the "graphical" version; there's also a text-only version, based on the console:
+```Lua
+local ctr = require("ctr")
+local gfx = require("ctr.gfx")
+local hid = require("ctr.hid")
+
+gfx.console()
+print("Hello, world !")
+
+while ctr.run() do
+	hid.read()
+	local keys = hid.keys()
+	if keys.held.start then break end
+
+	gfx.render()
+end
+
+gfx.disableConsole()
+```
