 Install the plugin globally or locally, depending on your setup
 
+```shell
+# Install the plugin globally if Artillery is installed globally:
+npm install artillery-plugin-metrics-by-endpoint -g
+
+# Or install into a project's dependencies:
+npm install --save-dev artillery-plugin-metrics-by-endpoint
 ```
-// global plugin installation
- npm install artillery-plugin-metrics-by-endpoint -g
- 
- // local plugin installation
- npm install --save-dev artillery-plugin-metrics-by-endpoint
-```

 Enable the plugin in the config
- 
-```
+
+```yaml
 config:
   plugins:
     metrics-by-endpoint: {}
 ```
-
+
+Run your tests as normal. There will additional output in the reports, providing latency metrics for each HTTP endpoint hit by the test.
+
+By default the plugin will treat each unique URL as a separate endpoint, e.g. if you tests makes requests to the following URLs:
+
+1. `/foos/1`
+2. `/foos/2`
+
+The report will contain latency metrics for both of those URLs. To treat those requests as the same endpoint, add a `name` atribute to the request in your test, and set `useOnlyRequestNames` option in plugin config:
+
+```yaml
+config:
+  target: "https://my-app.acme-corp.internal"
+  plugins:
+    metrics-by-endpoint:
+      useOnlyRequestNames: true
+scenarios:
+  - flow:
+      - loop:
+        - get:
+            url: "/foos/{{ $loopElement }}"
+            name: "orders"
+        count: 100
+```
