2. Before embarking on any significant pull request, please open an issue describing the changes you intend to make. Otherwise you risk spending a lot of time working on something I may not want to merge. This also tells other contributors that you're working on the feature.
**Important:** the documentation's license must permit alteration, redistribution and commercial use, and the documented software must be released under an open source license. Feel free to get in touch if you're not sure if a documentation meets those requirements.
In addition to the [guidelines for contributing code](#contributing-code-and-features), the following guidelines apply to pull requests that add a new documentation:
* Your documentation must come with an official icon, in both 1x and 2x resolutions (16x16 and 32x32 pixels). This is important because icons are the only thing differentiating search results in the UI.
* DevDocs favors quality over quantity. Your documentation should only include documents that most developers may want to read semi-regularly. By reducing the number of entries, we make it easier to find other, more relevant entries.
Please don't submit a pull request updating the version number of a documentation, unless a change is required in the scraper and you've verified that it works.
* **Improve our copy.** English isn't my first language so if you notice grammatical or usage errors, feel free to submit a pull request — it'll be much appreciated.
* **Participate in the issue tracker.** Your opinion matters — feel free to add comments to existing issues. You're also welcome to participate to the [mailing list](https://groups.google.com/d/forum/devdocs).
