Official website and documentation for Less/Less.js

## Quickstart

Assemble and Grunt are used to build the docs. To get started:

1. Download the docs
2. In the root of the project, run `npm install`
3. Run the `grunt` command to build the docs

If all worked properly, you're ready to begin contributing to the docs!

### Documentation

All documentation content can be found in the `./content` directory. Please read the **contributing** section below if you wish to add documentation.

## The Plan

1. Clean up and organize all of the documentation in the [content](./content) directory, which means
2. Consistent naming conventions for files, consistent coding styles in documents
3. Organize information and favor individual files for sections of content, rather than long documents
4. Last, a new theme.

## Contributing
### Coding Style
> Please help us make the documentation _consistent, readable, and maintainable_ by conforming to these guidelines when contributing:

#### Less, LESS or Less.js?

The name of the project is **Less**. Anywhere in the docs, **Less** means both the language and its official, reference implementation.
The **less.js** form is normally to be used only to specify either of:
* the browser script file name
* the particular GitHub [repository](https://github.com/less/less.js) (where most of the development takes place)

##### Examples:
- *"Less language", "Less library", "Less API", "Less plugin", "Using Less" etc.*
- *"Fork [less/less.js](https://github.com/less/less.js) repository"* (synonyms: *"Less Repository", "Main Repository"* etc.)
- *"Make sure to include your stylesheets before the [less.js](https://github.com/less/less.js/blob/v2.7.2/dist) script"*

#### Capitalization

##### In Titles: Do Capitalize

* Nouns (man, bus, book)
* Adjectives (angry, lovely, small)
* Verbs (run, eat, sleep)
* Adverbs (slowly, quickly, quietly)
* Pronouns (he, she, it)
* Subordinating conjunctions (as, because, that)

##### In Titles: Do Not Capitalize

* Articles: a, an, the
* Coordinating Conjunctions: and, but, or, for, nor, etc.
* Prepositions: on, at, to, from, by, etc.

#### Markdown standards

* Use `#` for titles, not underlines. Underlines are not semantic, aren't as flexible, aren't always highlighted properly in code highlighters
* Always add a space between the `#` and the heading
* Wrap inline code with a **single backtick**,
* wrap blocks of code with **three backticks** (code fences).
* With code blocks, _always use the correct language_ after the first code fence. Although GitHub does not highlight Less, our documentation is more likely to show up in GitHub's and Google's search results when the correct language is used. Examples: please use \`\`\`less for Less, and \`\`\`css for CSS.

#### Less standards

* Two spaces for indentation, never tabs, and always use proper indentation
* Multiple-line formatting (one property and value per line)
* For multiple, comma-separated selectors, place each selector on its own line
* Double quotes only, never single quotes
* Always put a space after a property's colon (e.g., `display: block;` and not `display:block;`)
* End _all_ lines with a semi-colon
* Attribute selectors, like `input[type="text"]` should always wrap the attribute's value in double quotes. This is important to do in your own code as well for consistency and safety (see this [blog post on unquoted attribute values](http://mathiasbynens.be/notes/unquoted-attribute-values) that can lead to XSS attacks)
* When using HTML in your examples, use tags and elements appropriate for an HTML5 doctype (e.g., self-closing tags with _no trailing slash_)
* Separate words in variable and mixin names using dash (e.g., `@long-variable-name` or `.my-favourite-mixin`)

Examples:

**Good**

```css
body {
padding-top: 80px;
font-size: 12px;
}
```

**Bad**

```css
body {
padding-top: 80px;
font-size: 12px;
}
```

**Bad**

```css
body { padding-top: 80px; font-size: 12px }
```

Also, please ensure that all documentation files should have globally-unique names, regardless of where they are located in the repository. This makes it easier to use conveniences like file globbing, and it's good practice anyway.

### Feature Requests, Bugs and Pull Requests

* If you would like to request a feature, suggest an improvement, or report a bug, please [submit an Issue](https://github.com/less/less.js/issues?state=open).
* Feature requests are more likely to get attention if you include a clearly described use case.
* If you wish to submit a pull request, please [read this first](https://github.com/less/less.js/blob/master/CONTRIBUTING.md).

## Tools

The documentation site is generated using [Assemble](http://assemble.io). Please visit that project [to report bugs](https://github.com/assemble/assemble/issues?state=open), or to learn more about usage and customization.

## Build the docs

Update the project with the most recent metadata from the Less.js project, such as current version number, description, and so on, and then run Grunt with the following command:

```bash
node data/_utils/pkg && grunt
```
