Hugo gives you two options, that you can set with the variable `pygmentsuseclasses` (defaut `false`) in the `config.yaml` (or `config.toml`).
On Debian and Ubuntu systems, you may also install Pygments by running `sudo apt-get install python3-pygments`.
1. color-codes for highlighting keywords are directly inserted if `pygmentsuseclasses: false` (default). See in the example below. The color-codes depend on your choice of the `pygmentsstyle` (default `"monokai"`). You can explore the different color styles on [pygments.org](http://pygments.org/) after inserting some example code.
2. if you choose `pygmentsuseclasses: true` Hugo includes class names in your code instead of color-codes. For class-names to be meaningful you need to include a `.css`-file in your website representing your color-scheme. You can either generate this `.css`-files according to this [description](http://pygments.org/docs/cmdline/) or download the standard ones from the [github pygments-css repository](https://github.com/richleland/pygments-css).

### Usage
Highlighting is carried out via the in-built shortcode `highlight`. `highlight` takes exactly one required parameter of language and requires a
closing shortcode.
### Example
If you want to highlight code you need to either fence the code with ``` according to Github flavored Markdown or each line must be preceeded by 4 spaces to identify each line as a line of code.
