## Library Usage

Below is the minimal usage of using `markdown` as a library.

```nim

import markdown

# 2. transform md to html.
let html = markdown("# Hello World\nHappy writing Markdown document!")

# 3. do something :)
echo(html)
```

## Binary Usage

The usage of binary `markdown` is as below:

```
# Read from stdin and write to stdout.
$ markdown < README.md > README.html
```

## Development

Build markdown binary:

```bash

```

Test markdown modules:

$ nimble test
```

Build document:

```bash
$ nim doc --project --git.url=https://github.com/soasme/nim-markdown --git.commit=v0.8.0 src/markdown.nim
```
