 Note: Everything in this project can be changed at anytime! (I'm still finding out what work best for lots of thing) if you have an idea, feel free to create an issues about it, or even create a PR! (I'd be very happy)
 
+# Contributing
+Found a bug? Found a better way to do something? Make a pull request or tell me in the issues tab! Anything contributions helps :D
+
+Wanna see how it works under the hood? see the [How it works](https://github.com/azur1s/hazure#how-it-works) tab, you should probably understand it a bit more.
+
+Steps to build:
+1) Clone this repo `https://github.com/azur1s/hazure.git`
+2) Run `sudo make build-lib` to build the library (for the transpiled output)
+3) Build executable `cargo build`
+4) Try running some examples! `path/to/executable compile path/to/file.hz`
