14+You can also use [Markdown](https://en.wikipedia.org/wiki/Markdown)-style text emphasis
15+- `_<text>_` or `*<text>*` for _italic_
16+- `__<text>__` or `**<text>**` for __bold__
17+- `___<text>___` or `***<text>***` for ___italic and bold___

24+```
25+![](images/mat2.png)

27+You can use `_` to leave an empty space in the matrix

59+`#` is used to make a `separator` comment. It separates your expressions into different `<math>` elements and is converted to an `xml` comment in the output document.
60+
61+## Usage
62+`mathdown -b:r -i input.mth -o output.xml`
63+
64+### Parameters
65+- `-i <file path>` Specifies the input path
66+- `-o <file path>` Specifies the output pathfile
67+- `-b:s` Uses square brackets
68+- `-b:r` Uses round brackets
69+- `-b:l` Uses line brackets
