+# ctru-rs
+
+A Rust wrapper library for smealum's
+[ctrulib](https://github.com/smealum/ctrulib). Intended for use only when
+targeting CTR.
+
+## How to build
+
+1. Install the devkitARM toolchain for your system. Make sure `DEVKITPRO` is
+   set in your environment.
+2. Modify ~/.cargo/config and add the following lines:
+
+```toml
+    [target.3ds]
+    ar = "/path/to/arm-none-eabi-ar"
+```
+
+3. Build with `cargo build --target 3ds.json`.
+4. A dkA linkable .rlib (static library) will be generated. Read below for
+instructions on using.
+
+## How to use
+
+You can build your homebrew projects through Cargo just as easily as any other
+platform. Add this to your `Cargo.toml`:
+
+```toml
+    [dependencies.core]
+    git="https://github.com/hackndev/rust-libcore"
+
+    [dependencies.ctru-rs]
+    git="https://github.com/Furyhunter/ctru-rs"
+```
+
+Copy the `3ds.json` target file to your project root and pass `--target
+3ds.json` whenever building. The instructions above for cargo configuration and
+environment still apply. It's recommended that you put the `bin` dir in your
+dkA root to your path.
+
+Your homebrew's crate must specify that it does not use `std`, because `std`
+is not available for the 3ds. `core` is a small subset of `std`'s functionality
+that is platform agnostic. You can `use core::prelude::*` to recover much of
+std's prelude, after `extern crate core`. This library makes use of core only.
+
+## Contributing
+
+This is a thin wrapper library **only**, any additional Rust-centric support
+code for the 3DS will be put into another package. However, the wrapper is
+incomplete, so PR's to finish it are helpful.
