+# Using Draco Command Line Applications
+
+This guide will show you how to build, and use the Draco command line
+applications to encode and decode Draco files.
+
+## Building
+
+Clone the Github repository using this command line:
+```
+git clone git@github.com:<username>/draco.git
+```
+_**Note** that we **strongly** recommend [using SSH] with GitHub, not HTTPS._
+
+
+Build the command line applications with these commands:
+```
+cd draco
+```
+
+It is best to create an isolated build directory.
+```
+mkdir build
+cd build
+```
+
+Run cmake to build `draco_encoder` and `draco_decoder`.
+```
+cmake ..
+make
+```
+
+## Encode Draco File
+
+Encode a mesh file using the default settings. `draco_encoder` will read OBJ or PLY files as input, and output Draco files. We have included Stanford's Bunny mesh for testing. The basic command line looks like this:
+```
+./draco_encoder -i ../testdata/bun_zipper.ply -o bunny.drc
+```
+
+
+## Decode Draco File
+
+`draco_decoder` will read Draco files as input, and output OBJ or PLY files. The basic command line looks like this:
+```
+./draco_encoder -i bunny.drc -o bunny.ply
+```
