-Package goquery implements features similar to jQuery, including the chainable
-syntax, to manipulate and query an HTML document.
-
-It brings a syntax and a set of features similar to jQuery to the Go language.
-It is based on Go's net/html package and the CSS Selector library cascadia.
-Since the net/html parser returns nodes, and not a full-featured DOM
-tree, jQuery's stateful manipulation functions (like height(), css(), detach())
-have been left off.
-
-Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is
-the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML.
-See the repository's wiki for various options on how to do this.
-
-Syntax-wise, it is as close as possible to jQuery, with the same method names when
-possible, and that warm and fuzzy chainable interface. jQuery being the
-ultra-popular library that it is, writing a similar HTML-manipulating
-library was better to follow its API than to start anew (in the same spirit as
-Go's fmt package), even though some of its methods are less than intuitive (looking
-at you, index()...).
-
-It is hosted on GitHub, along with additional documentation in the README.md
-file: https://github.com/puerkitobio/goquery
-
-Please note that because of the net/html dependency, goquery requires Go1.1+.
-
-The various methods are split into files based on the category of behavior.
-The three dots (...) indicate that various "overloads" are available.
-
-* array.go : array-like positional manipulation of the selection.
- - Eq()
- - First()
- - Get()
- - Index...()
- - Last()
- - Slice()
-
-* expand.go : methods that expand or augment the selection's set.
- - Add...()
- - AndSelf()
- - Union(), which is an alias for AddSelection()
-
-* filter.go : filtering methods, that reduce the selection's set.
- - End()
- - Filter...()
- - Has...()
- - Intersection(), which is an alias of FilterSelection()
- - Not...()
-
-* iteration.go : methods to loop over the selection's nodes.
- - Each()
- - EachWithBreak()
- - Map()
-
-* manipulation.go : methods for modifying the document
- - After...()
- - Append...()
- - Before...()
- - Clone()
- - Empty()
- - Prepend...()
- - Remove...()
- - ReplaceWith...()
- - Unwrap()
- - Wrap...()
- - WrapAll...()
- - WrapInner...()
-
-* property.go : methods that inspect and get the node's properties values.
- - Attr*(), RemoveAttr(), SetAttr()
- - AddClass(), HasClass(), RemoveClass(), ToggleClass()
- - Html()
- - Length()
- - Size(), which is an alias for Length()
- - Text()
-
-* query.go : methods that query, or reflect, a node's identity.
- - Contains()
- - Is...()
-
-* traversal.go : methods to traverse the HTML document tree.
- - Children...()
- - Contents()
- - Find...()
- - Next...()
- - Parent[s]...()
- - Prev...()
- - Siblings...()
-
-* type.go : definition of the types exposed by goquery.
- - Document
- - Selection
- - Matcher
-
-* utilities.go : definition of helper functions (and not methods on a *Selection)
-that are not part of jQuery, but are useful to goquery.
- - NodeName
- - OuterHtml

-# How to Contribute
-
-CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
-GitHub pull requests. This document outlines some of the conventions on
-development workflow, commit message formatting, contact points and other
-resources to make it easier to get your contribution accepted.
-
-# Certificate of Origin
-
-By contributing to this project you agree to the Developer Certificate of
-Origin (DCO). This document was created by the Linux Kernel community and is a
-simple statement that you, as a contributor, have the legal right to make the
-contribution. See the [DCO](DCO) file for details.
-
-# Email and Chat
-
-The project currently uses the general CoreOS email list and IRC channel:
-- Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev)
-- IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org
-
-Please avoid emailing maintainers found in the MAINTAINERS file directly. They
-are very busy and read the mailing lists.
-
-## Getting Started
-
-- Fork the repository on GitHub
-- Read the [README](README.md) for build and test instructions
-- Play with the project, submit bugs, submit patches!
-
-## Contribution Flow
-
-This is a rough outline of what a contributor's workflow looks like:
-
-- Create a topic branch from where you want to base your work (usually master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- Make sure the tests pass, and add any new tests as appropriate.
-- Submit a pull request to the original repository.
-
-Thanks for your contributions!
-
-### Format of the Commit Message
-
-We follow a rough convention for commit messages that is designed to answer two
-questions: what changed and why. The subject line should feature the what and
-the body of the commit should describe the why.
-
-```
-scripts: add the test-cluster command
-
-this uses tmux to setup a test cluster that you can easily kill and
-start for debugging.
-
-Fixes #38
-```
-
-The format can be described more formally as follows:
-
-```
