-To explore k6 metrics in Grafana Cloud:
-1. Click on the Explore icon on the menu bar.
-1. Choose the Prometheus data source from the dropdown in the top left.
-1. In the query field, query k6 metrics to explore your testing results.
+To visualize test results with Grafana, you can import the [k6 Prometheus dashboard by Grafana k6](https://grafana.com/grafana/dashboards/19665-k6-prometheus/).
+
+On the Dashboards UI:
+
+- Click `New` and select `Import`.
+- Paste the Grafana URL or ID of the dashboard, and click `Load`.
+- Select the Prometheus data source, and click `Import`.
+
+![k6 Prometheus Dashboard](./images/Prometheus/k6-prometheus-dashboard-part1.png)
+
+Optionally, when running the test, you can set the `testid` tag as a [wide test tag](https://k6.io/docs/using-k6/tags-and-groups/#test-wide-tags) to filter results of a particular test run on this dashboard (or in PromQL queries). `testid` can be any unique string that allows you to identify the test run.

+k6 run -o experimental-prometheus-rw --tag testid=TEST_ID script.js

+
+Additionally, you can also use the [Explore UI](https://grafana.com/docs/grafana/latest/explore/) to query k6 time series, design your visualization panels, and add them to any of your existing dashboards.

+All the k6 time series have a **k6_** prefix. 
+For more details, refer to the documentation on the [mapping of k6 metrics with Prometheus metrics](/results-output/real-time/prometheus-remote-write/#metrics-mapping). 
+
+It's also important to understand the default [Trend metric conversion](/results-output/real-time/prometheus-remote-write/#trend-metric-conversions) process and the format and querying limitations. The [`K6_PROMETHEUS_RW_TREND_STATS` option](/results-output/real-time/prometheus-remote-write/#options) allows you to convert trend metrics to multiple Prometheus time series. For instance, `K6_PROMETHEUS_RW_TREND_STATS=p(95),p(99),max,min` transforms each k6 trend metric into four Prometheus metrics as follows:
+
+- `k6_*_p95`
+- `k6_*_p99`
+- `k6_*_max`
+- `k6_*_min`
