+# Procedura 1D terrain generator
+
+This is a demo of a 1D terrain generator using [Perlin noise](https://en.wikipedia.org/wiki/Perlin_noise) algorithm.
+Press *space* to generate a random terrain.
+
+Uses [Go-Perlin](https://github.com/aquilax/go-perlin).
+
+Texture by [hh316](https://hhh316.deviantart.com/art/Seamless-stone-cliff-face-mountain-texture-377076626).
