+It returns `200 OK` when Ggr operates normally. Additionally, server uptime, last quota reload time and overall number of session requests from service startup are returned in JSON format.
 
 === Why Ggr is Stateless
 Selenium uses an HTTP-based protocol. That means every action in Selenium, e.g. launching browser or taking screenshot is a separate HTTP request. When multiple instances of Ggr are handling requests behind load balancer every request can be routed to any of these instances. Here's how it works.
@@ -25,7 +25,7 @@ On the picture above there is one SLB, two instances of Ggr and one Selenium hub
 
 For example let's assume that new session request is routed to `Ggr 1` (black arrows). This Ggr randomly chooses a hub `hub1.example.com` and creates a new session on it. This hub returns some session identifier marked as `ID` on the picture. `Ggr 1` in its turn knows that session was created on `hub1.example.com` and extends the session ID by adding an MD5 sum `S` of hub hostname. This is why it returns to user new longer session with identifier `S+ID` just by concatenating two strings. Every Ggr instance during startup creates an in-memory map - storing host names and their MD5 sums. When consequent request for the same session `S+ID` arrives e.g. to `Ggr 2` (red arrows) it extracts `S` from extended session ID and finds hub hostname in its map. Then it removes `S` from request session identifier and simply proxies this request to hub corresponding to `S`.
 
-IMPORTANT: Because of stateless Ggr architecture you can use an unlimited number of Ggr instances behind load balancer. In order to work properly it is very important to have exactly the same XML quota files on every Ggr instance. Otherwise some Ggr instances will return `404` error when a request with unknown host `S` arrives.

 . Browser name is matched against `browserName` capability. Values are compared as strings and should be exactly equal. When testing mobile applications (e.g. with http://github.com/appium/appium[Appium]) `browserName` capability makes no sense and can be replaced by `deviceName` or `appium:deviceName` capability. Ggr will try to match both against browser name specified in XML.
 . Version `number` is matched against `version` or `browserVersion` capability by prefix. For example both `61` and `61.0` in version capability (i.e. in your code) will match version number `61.0`.
