+apicula is written in [Rust](https://www.rust-lang.org/). Make sure it is
+[installed](https://www.rust-lang.org/en-US/install.html).
+
+1. Clone the git repo
+
+        $ git clone https://github.com/scurest/apicula.git
+
+3. Change into the `apicula` directory
+
+        $ cd apicula
+
+3. Build the project with Cargo (this will take a while)
+
+        $ cargo build --release

+The [Nitro file

+the formats for Nintendo's SDK for DS game developers and were used by many DS
+games. This tool is for dealing with Nitro models (NSBMD files), viewing them,
+and converting them to COLLADA .dae files. There is also support for loading
+textures (NSBTX) and animations (NSBCA).

-Many NDS games used Nintendo's Nitro SDK format for models (NSBMD), textures (NSBTX), and
-animations (NSBCA). apicula let's you convert these models to `.dae` files.
