5 Your map should include a preview picture. This picture will be visible from the game menu and from the servers vote screen.
8 * Load your map in the game
9 * Use the command `r_letterbox -1` in the console to turn off the HUD
10 * If your map has "waypoint" entities (like CTF or CTS maps), you can hide them with `cl_hidewaypoints 1`
11 * Take a nice screenshot with F12
12 * Go to your Xonotic user directory, on the `data/screenshot` subdirectory. Your user directory location depends on your operating system, more information [here](https://xonotic.org/faq/#config).
13 * Open the screenshot with an image editor, e.g. GIMP
14 * Crop it so that it has a 4:3 ratio
15 * Scale it to 512x512 px (weird but standard)
16 * Save it as a JPG file (~90% quality)
17 * Put it in the same location as the bsp file, with the same name (see next chapter for packaging rules).
