| Once you've created a `bootstrap.toml`, you are now ready to run | ||
| `x`. There are a lot of options here, but let's start with what is | ||
| probably the best "go to" command for building a local compiler: | ||
|
|
||
| ```bash | ||
| ./x build library | ||
| ```console | ||
| ./x build rustc | ||

Unfortunately, the current text (./x build rustc) is now incorrect, because that command doesn't produce a fully-functional compiler (since it doesn't have libraries in its sysroot).
So ./x build library is actually the necessary command.
