-https://wakatime.com/
+Install the plugin for your IDE/editor at https://wakatime.com/plugins
+
+If you are building a plugin using the [WakaTime API](https://wakatime.com/developers/)
+then follow the [Creating a Plugin](https://wakatime.com/help/misc/creating-plugin)
+guide for information about using `wakatime-cli.py`.
+
+
+Configuring
+-----------
+
+Options can be passed via command line, or set in the `$HOME/.wakatime.cfg`
+config file. Command line arguments take precedence over config file settings.
+The `$HOME/.wakatime.cfg` file is in [INI](http://en.wikipedia.org/wiki/INI_file)
+format. An example config file looks like:
+
+```
+[settings]
+debug = false
+api_key = your-api-key
+hidefilenames = false
+ignore =
+    ^COMMIT_EDITMSG$
+    ^TAG_EDITMSG$
+    ^/var/
+    ^/etc/
+offline = true
+proxy = https://user:pass@localhost:8080
+```
+
+
+Installation
+------------
+
+Each plugin installs wakatime for you, but for testing you can install the
+common api interface with pip:
+
+    pip install wakatime
