 Frontends can be defined using the following rules:
 
-- `Headers`: Headers adds a matcher for request header values. It accepts a sequence of key/value pairs to be matched. For example: `application/json`
-- `HeadersRegexp`: Regular expressions can be used with headers as well. It accepts a sequence of key/value pairs, where the value has regex support. For example: `application/(text|json)`
+- `Headers`: Headers adds a matcher for request header values. It accepts a sequence of key/value pairs to be matched. For example: `Content-Type, application/json`
+- `HeadersRegexp`: Regular expressions can be used with headers as well. It accepts a sequence of key/value pairs, where the value has regex support. For example: `Content-Type, application/(text|json)`
 - `Host`: Host adds a matcher for the URL host. It accepts a template with zero or more URL variables enclosed by `{}`. Variables can define an optional regexp pattern to be matched: `www.traefik.io`, `{subdomain:[a-z]+}.traefik.io`
 - `Methods`: Methods adds a matcher for HTTP methods. It accepts a sequence of one or more methods to be matched, e.g.: `GET`, `POST`, `PUT`
 - `Path`: Path adds a matcher for the URL path. It accepts a template with zero or more URL variables enclosed by `{}`. The template must start with a `/`. For exemple `/products/` `/articles/{category}/{id:[0-9]+}`
@@ -54,18 +54,23 @@ Various methods of load-balancing is supported:
 - `drr`: Dynamic Round Robin: increases weights on servers that perform better than others. It also rolls back to original weights if the servers have changed.
 
 A circuit breaker can also be applied to a backend, preventing high loads on failing servers.
+Initial state is Standby. CB observes the statistics and does not modify the request.
+In case if condition matches, CB enters Tripped state, where it responds with predefines code or redirects to another frontend.
+Once Tripped timer expires, CB enters Recovering state and resets all stats.
+In case if the condition does not match and recovery timer expries, CB enters Standby state.
+
 It can be configured using:
 
 - Methods: `LatencyAtQuantileMS`, `NetworkErrorRatio`, `ResponseCodeRatio`
 - Operators:  `AND`, `OR`, `EQ`, `NEQ`, `LT`, `LE`, `GT`, `GE`
 
 For example:
-- `NetworkErrorRatio() > 0.5`
-- `LatencyAtQuantileMS(50.0) > 50`
-- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`
+- `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window for a frontend
+- `LatencyAtQuantileMS(50.0) > 50`:  watch latency at quantile in milliseconds.
+- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`: ratio of response codes in range [500-600) to  [0-600)

+## Atomic configuration changes
 
 The [Etcd](https://github.com/coreos/etcd/issues/860) and [Consul](https://github.com/hashicorp/consul/issues/886) backends do not support updating multiple keys atomically. As a result, it may be possible for Træfɪk to read an intermediate configuration state despite judicious use of the `--providersThrottleDuration` flag. To solve this problem, Træfɪk supports a special key called `/traefik/alias`. If set, Træfɪk use the value as an alternative key prefix.

 Note that Træfɪk *will not watch for key changes in the `/traefik_configurations` prefix*. It will only watch for changes in the `/traefik` prefix. Further, if the `/traefik/alias` key is set, all other sibling keys with the `/traefik` prefix are ignored.
