Ser, just add text or ignore.

```ignore
solc, the solidity compiler commandline interface
Version: 0.8.12+commit.f00d7308.Darwin.appleclang
```

Thanks @ZeroEkkusu!! Do you know what causes that? Is it a linter? Or some new style guideline?

I feel like I've done a lot of code blocks in md and never been forced to enter the language before

@devtooligan see here 🙂 https://rust-lang.github.io/mdBook/cli/test.html

@mds1 v interesting thanks ser

[onbjerg]

Thank you for this! 😄 And yes, the lint is an mdbook-specific thing. Basically, mdbook was built for Rust projects first, so it will actually try to validate some of the codeblocks to see that they work
