# 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.
