+# About chromedp
+
+Package chromedp is a faster, simpler way to drive browsers in Go using the
+[Chrome Debugging Protocol](https://developer.chrome.com/devtools/docs/debugger-protocol)
+(for Chrome, Edge, Safari, etc) without external dependencies (ie, Selenium, PhantomJS, etc).
+
+**NOTE:** chromedp's API is currently unstable, and may change at a moments
+notice. There are likely extremely bad bugs lurking in this code. **CAVEAT USER**.
+
+## Installation
+
+Install in the usual way:
+
+```sh
+go get -u github.com/knq/chromedp
+```
+
+## Usage
+
+Please see the [examples](examples/) directory for examples.
+
+## TODO
+* Move timeouts to context (defaults)
+* Implement more query selector options (allow over riding context timeouts)
+* Contextual actions for "dry run" (or via an accumulator?)
+* Network loader / manager
+* More examples
+* Profiler
+* Unit tests / coverage: travis-ci + coveralls integration
