# libtock-rs
Rust userland library for Tock (WIP)
+
+## Getting Started
+
+This project is nascent and still under heavy development, but first steps:
+
+1. Get a copy of the latest nightly, in this repo's root:
+
+ `rustup override set nightly`
+
+2. Need to grab a copy of the rust sources:
+
+ `rustup component add rust-src`
+
+3. Now you should be able to build with:
+
+ `xargo build --target thumbv7em-tock-eabi`
