SIG Systems Shell

This shell is the UIC ACM's SIG Systems' first project!

Guides

Getting started running the shell

1. Use the rustup Rust installer to get your environment setup and ready to build the shell.
   • There are rustup installers available for Linux, Windows, and MacOS.
     • Linux and MacOS users need only to run a quick command.
2. Use git clone to clone this repo, then cd into it.
3. Run cargo run in your terminal to startup the (quite unfinished) shell.
4. Make some changes to src/main.rs then type cargo run again to see what changes!

Getting started collaborating

1. Fork the repository with the "Fork" button in the top right.
2. Either clone the newly-forked repository or (if you sufficiently understand git), add it as a new remote.
3. Make, commit, and push your changes (to your forked repo).
4. On the GitHub page for your forked repo, under the "Contribute" button on top, press "Open pull request"
5. Write a brief description of what your code changes do.
6. Press the "Create pull request" button.
7. Watch your email for updates!
