+Awesome, this is exactly what we wanted. If you haven’t caught on yet we can emulate entire charts from Netdata by using
 the `chart` dimension. If you’d like you can combine the ‘chart’ and ‘instance’ dimension to create per-instance charts.
 Let’s give this a try: `netdata_system_cpu_percentage_average{chart="system.cpu", instance="netdata:19999"}`

+This is the basics of using Prometheus to query Netdata. I’d advise everyone at this point to read [this
+page](../backends/prometheus/#using-netdata-with-prometheus). The key point here is that Netdata can export metrics from
 its internal DB or can send metrics “as-collected” by specifying the ‘source=as-collected’ url parameter like so.
 <http://localhost:19999/api/v1/allmetrics?format=prometheus&help=yes&types=yes&source=as-collected> If you choose to use
 this method you will need to use Prometheus's set of functions here: <https://prometheus.io/docs/querying/functions/> to
 obtain useful metrics as you are now dealing with raw counters from the system. For example you will have to use the
 `irate()` function over a counter to get that metric's rate per second. If your graphing needs are met by using the
-metrics returned by NetData's internal database (not specifying any source= url parameter) then use that. If you find
+metrics returned by Netdata's internal database (not specifying any source= url parameter) then use that. If you find
 limitations then consider re-writing your queries using the raw data and using Prometheus functions to get the desired
 chart.
