Our personal preference is to use Visual Studio Code (VS Code), which has excellent, official support from the Rust language team. Other options are available [here](https://areweideyet.com/), but we don't recommend them.

For VS Code, recommended plugins are:
* Rust (rls), by rust-lang
* Better TOML, by bungcip
* x86 and x86_64 Assembly, by 13xforever

### Fixing RLS Problems
Sometimes RLS just doesn't want to behave, especially if the latest Rust nightly version had build errors. In that case, try the following steps to fix it:
* Set your default Rust toolchain to the one version in the `rust-toolchain` file, for example:
`rustup default nightly-2019-07-09`.
* With your newly-set default toolchain, add the necessary components:
`rustup component add rls rust-analysis rust-src`.
* In VS Code (or whatever IDE you're using), uninstall and reinstall the RLS extension, reloading the IDE each time.
* Check your IDE's settings to make sure that no weird rust or RLS settings have been set; building Theseus doesn't require any special RLS settings.
* If you're still having lots of issues, remove all other toolchains besides the default one and try again.
You can see other installed toolchains with `rustup toolchain list`.

PRs and issues are welcome from anyone; because Theseus is an experimental OS, certain features may be deprioritized or excluded from the main branch. Don't hesitate to ask or mention something though! :smile:
