-## Piwik Proxy Hide URL
-This script allows to track statistics using Piwik, without revealing the
-Piwik Server URL. This is useful for users who track multiple websites
-on the same Piwik server, but don't want to show the Piwik server URL in
-the source code of all tracked websites.
+# Piwik Proxy Hide URL
 
-### Requirements
-To run this properly you will need
-
- * Piwik server latest version
- * One or several website(s) to track with this Piwik server, for example http://trackedsite.com
- * The website to track must run on a server with PHP5 support
- * In your php.ini you must check that the following is set: `allow_url_fopen = On`
-
-### How to track trackedsite.com in your Piwik without revealing the Piwik server URL?
-
-1. In your Piwik server, login as Super user
-2. create a user, set the login for example: "UserTrackingAPI"
-3. Assign this user "admin" permission on all websites you wish to track without showing the Piwik URL
-4. Copy the "token_auth" for this user, and paste it below in this file, in `$TOKEN_AUTH = "xyz"`
-5. In this file, below this help test, edit $PIWIK_URL variable and change http://your-piwik-domain.example.org/piwik/ with the URL to your Piwik server.
-6. Upload this modified piwik.php file in the website root directory, for example at: http://trackedsite.com/piwik.php
-   This file (http://trackedsite.com/piwik.php) will be called by the Piwik Javascript,
-   instead of calling directly the (secret) Piwik Server URL (http://your-piwik-domain.example.org/piwik/).
-7. You now need to add the modified Piwik Javascript Code to the footer of your pages at http://trackedsite.com/
-   Go to Piwik > Settings > Websites > Show Javascript Tracking Code.
-   Copy the Javascript snippet. Then, edit this code and change the last lines to the following:
-
-   ```
-   [...]
-   (function() {
-       var u="//trackedsite.com/";
-       _paq.push(["setTrackerUrl", u+"piwik.php"]);
-       _paq.push(["setSiteId", "trackedsite-id"]);
-       var d=document, g=d.createElement("script"), s=d.getElementsByTagName("script")[0];
-       g.type="text/javascript"; g.async=true; g.defer=true; g.src=u+"piwik.php"; s.parentNode.insertBefore(g,s);
-   })();
-   </script>
-   <!-- End Piwik Code -->
-   ```
-
-   What's changed in this code snippet compared to the normal Piwik code?
-
-   * the (secret) Piwik URL is now replaced by your website URL
-   * the "piwik.js" becomes "piwik.php" because this piwik.php proxy script will also display and proxy the Javascript file
-   * the `<noscript>` part of the code at the end is removed,
-     since it is not currently used by Piwik, and it contains the (secret) Piwik URL which you want to hide.
-   * make sure to replace trackedsite-id with your idsite again.
-
- 8. Paste the modified Piwik Javascript code in your website "trackedsite.com" pages you wish to track.
-    This modified Javascript Code will then track visits/pages/conversions by calling trackedsite.com/piwik.php
-    which will then automatically call your (hidden) Piwik Server URL.
- 9. Done!
-    At this stage, example.com should be tracked by your Piwik without showing the Piwik server URL.
-    Repeat the steps 6, 7 and 8 for each website you wish to track in Piwik.
+The proxy script has been moved to [piwik/tracker-proxy](https://github.com/piwik/tracker-proxy).
