# Top heading

- Only multi-line comments are supported for Markdown

- Haskell code snippet (use `hs`)

    ```hs
    "1+4+2+3"
    ```

- Console code snippet

```console
"1*2*3*4"
```

1. what's in comments is written as is
2. Haskell code becomes haskell code snippets

- There should be a line between a multi-line comment and Haskell code

- A Haskell snippet starts with a non-empty line that is not a part of a multi-line comment

- Magic comments will be skipped

- Haskell function docs won't

- If there's a single line btw Haskell code and a comment, this line is removed

the following two comments will be commented out due to a config

this LIMA_ENABLE reads like a comment because there's no corresponding
