+# Display API
+
+This library's purpose is to ease creation of nodes with one or more displays on sides. For example, signs and clocks. Display can be dynamic and/or different for each node instance.
+
+**Limitations**: This lib uses entities to draw display. This means display has to be vertical (and "upside up") on Minetest before version 5.0.
+
+**Dependancies**:default
+
+**License**: LGPLv2
+
+**API**: See [API.md](https://github.com/pyrollo/display_modpack/blob/master/display_api/API.md) document please.
+
+For more information, see the [forum topic](https://forum.minetest.net/viewtopic.php?t=19365) at the Minetest forums.
