 The following diagram shows an example of Prometheus remote write API usage, with Cortex,n open source, horizontally scalable, highly available, multi-tenant, long term storage, as a remote storage backend.

+![Cortex Architecture](img/cortex.png)
 
 Our project is focused on developing an exporter for the OpenTelemetry Collector to any Prometheus remote storage backend.
 
 ### **1.1 Remote Write API**
 
 The Prometheus remote write/Cortex exporter should write metrics to a remote URL in a snappy-compressed, [protocol buffer](https://github.com/prometheus/prometheus/blob/master/prompb/remote.proto#L22) encoded HTTP request defined by the Prometheus remote write API. Each request should encode multiple Prometheus remote write TimeSeries, which are composed of a set of labels and a collection of samples. Each label contains a name-value pair of strings, and each sample contains a timestamp-value number pair.
 
-![Image of TimeSeries](./img/timeseries.png)
+![Image of TimeSeries](img/timeseries.png)
 
 TimeSeries stores its metric name in its labels and does not describe metric types or start timestamps. To convert to TimeSeries data, buckets of a Histogram are broken down into individual TimeSeries with a bound label(`le`), and a similar process happens with quantiles in a Summary.
