+* `text`: The name of the texture to use.
+* `alignment`: The alignment of the image.
+* `offset`: Offset in pixels from position.
+* `dir`: How the image is rotated/translated:
+ * 0 - Rotate as heading direction
+ * 1 - Rotate in reverse direction
+ * 2 - Translate as landscape direction
+ * 3 - Translate in reverse direction
+
+If translation is chosen, texture is repeated horizontally to fill the whole element.
+
+### `minimap`
+
+Displays a minimap on the HUD.
+
+* `size`: Size of the minimap to display. Minimap should be a square to avoid
+ distortion.

+ or if their feet are in the node. Note: not supported for `new_move = false`
* `fall_damage_add_percent`: damage speed = `speed * (1 + value/100)`

* `float`: the node will not fall through liquids
Some of the values in the key-value store are handled specially:
-* `description`: Set the item stack's description. Defaults to
- `idef.description`.
+* `description`: Set the item stack's description.
+ See also: `get_description` in [`ItemStack`]
+* `short_description`: Set the item stack's short description.
+ See also: `get_short_description` in [`ItemStack`]

* `palette_index`: If the item has a palette, this is used to get the
current color from the palette.

+Server side translations
+------------------------
+
+On some specific cases, server translation could be useful. For example, filter
+a list on labels and send results to client. A method is supplied to achieve
+that:
+
+`minetest.get_translated_string(lang_code, string)`: Translates `string` using
+translations for `lang_code` language. It gives the same result as if the string
+was translated by the client.
+The `lang_code` to use for a given player can be retrieved from
+the table returned by `minetest.get_player_information(name)`.
+IMPORTANT: This functionality should only be used for sorting, filtering or similar purposes.
+You do not need to use this to get translated strings to show up on the client.
Perlin noise
============
preferable for this to be different from other seeds, but sometimes it is useful
to be able to create identical noise patterns.
-When used in mapgen this is actually a 'seed offset', it is added to the
-'world seed' to create the seed used by the noise, to ensure the noise has a
-different pattern in different worlds.
+In some noise APIs the world seed is added to the seed specified in noise
+parameters. This is done to make the resulting noise pattern vary in different
+worlds, and be 'world-specific'.
