+
+_Objects_ being visualized with this plugin may be different: not only IT components (e.g. server
+hosts and Kubernetes pods) but just anything you can imagine like coffee makers on the picture
+above. These objects should have _discrete statuses_ which are sets of predefined values, e.g.
+`ok` = 0, `off` = 1, `fail` = 2, etc.
 
 ## Configuration
 
-Recommended setup is to create query for each possible status value with similar legend:
+### Prometheus
+
+To work with data from Prometheus you will need to setup discrete statuses for your objects.
+Requirements to store these statuses in metrics are as follows:
+* metrics should have two values: `0` and `1`;
+* there should be a label with status' value.
+
+When it's done, you can collect all the data via query, e.g.:
+
+```
+(max_over_time(coffee_maker_status{status="<STATUS_VALUE>"}[$__interval]) == 1) * <STATUS_VALUE>
+```
+
+If there was no such status (`<STATUS_VALUE>`) during query's interval, Prometheus would
+return nothing. Otherwise, status' value will be returned.
+
+For example, if you have 5 types of statuses and a metric (`coffee_maker_status`) with 5
+allowed values (`0`, `1`, `2`, `3`, `4`), you should transform this metric using following rule:
+
+```
+- record: coffee_maker_status:discrete
+  expr: |
+    count_values("status", coffee_maker_status)
+```
+
+That's how `coffee_maker_status` metric with value `3` will be transformed into new metric:
+
+```
+coffee_maker_status:discrete{status="3"} 1
+```
+
+Now, when Prometheus has `0` and `1` values for each status, all these metrics can be
+aggregated, so you will get all available statuses of your objects over time.
+
+### Panel
+
+First of all, an individual query for each possible status' value should be created.
+Each query should also have similar legend for grouping:
 
 ![Query setup](https://raw.githubusercontent.com/flant/grafana-statusmap/master/src/img/queries-example.png)
 
-Next define color mapping for status values in __Discrete__ color mode.
+Then, color mapping for status' values should be defined in __Discrete__ color mode:
 
 ![Color mapping](https://raw.githubusercontent.com/flant/grafana-statusmap/master/src/img/color-mapping.png)
 
-
-__Spectrum__ and __Opacity__ color modes works as in a [Heatmap](https://grafana.com/plugins/heatmap) plugin.
+_Note: __Spectrum__ and __Opacity__ color modes function the same way they do in [Heatmap](https://grafana.com/plugins/heatmap) plugin._
 
 
 ### More options
 
 ![Bucket options](https://raw.githubusercontent.com/flant/grafana-statusmap/master/src/img/options-bucket.png)
 
-__Multiple values__ check determine multiple values display mode. If check is unset then multiple values
-for one bucket treated as error. If check is on then color for bucket determined
-by value with least index in color mapping.
+__Multiple values__ checkbox specifies how they should be displayed:
+* If it's off, multiple values for one bucket are treated as error;
+* If it's on, color for such bucket would be determined by the value having least index in color mapping.
 
 ![Color mapping](https://raw.githubusercontent.com/flant/grafana-statusmap/master/src/img/multiple-values-error.png)
 
-__Null values__ can be treated as empty buckets or displayed as color of 0 value.
+__Null values__ can be treated as empty buckets or displayed with the color of `0` value.

-__Min width__ and __spacing__ are determine minimal bucket width and spacing between buckets.
