+# No Coin
+No coin is a tiny browser extension aiming to block coin miners such as Coinhive.
+
+![v0.1 demo](https://ker.af/content/images/2017/09/nocoin-v0.1.gif)
+
+You can grab the extension from the Chrome Web Store: https://chrome.google.com/webstore/detail/no-coin/gojamcfopckidlocpkbelmpjcgmbgjcl
+
+Note: This is a very very early version, more features and a nicer design are planned. Also the code was written quite quickly during a [live stream](https://www.twitch.tv/iamkeraf), coming commits should be looking better :-)
+
+### Why?
+Even though I think using coin mining in browser to monetize content is a great idea, abusing it is not. Some websites are running it during the entire browsing session which results in high consumption of your computers resources. I do believe that using it occasionally such as for the proof of work of a captcha is OK. But for an entire browsing session, the user should have the choice to opt-in which is the aim of this extension.
+
+### How does it work?
+The extension is simply blocking a list of blacklisted domains in *blacklist.txt*. Clicking on the icon will display you a button to pause/unpause No Coin. If you are aware of any scripts or services that provide coin mining the browser, please submit a PR.
+
+## Contribute
+Contributions are welcome! Don't hesitate to submit bug fixes, improvements and new features. 
+
+Regarding new features, please have a look at the issues first. If a feature you whish to work on is not listed in here, you might want to add an issue first before starting to work on a PR.
