# About chromedp examples
This folder contains a variety of code examples for working with
[`chromedp`][1]. The package documentation contains a number of [simple
examples][2] which are self-contained, while this repository holds more complex
examples which tend to require internet access or external components.
Please note that these examples may break occassionally. Additionally, since
these examples are written for specific websites, there is a good chance that
the current selectors, etc. break after the website they are written against
changes.
While every effort is made to ensure that these examples are kept up-to-date,
it is expected that the examples made available here may occasionally break.
To file issues, use the [chromedp's issue tracker][3].
## Building and Running an Example
You can build and run these examples in the usual Go way:
```sh
# retrieve examples
$ go get -u -d github.com/chromedp/examples
# run example
$ go run $GOPATH/src/github.com/chromedp/examples//main.go
# build example
$ go build -o github.com/chromedp/examples/ && ./
```

## Contributing
Pull Requests and contributions to this project are encouraged and greatly
welcomed! The `chromedp` project always needs new examples, and needs talented
developers (such as yourself!) to submit fixes for the existing examples when
they break (for example, when a website's layout/HTML changes).
