+# Metrics store
+
+One of Iter8's key advantages is that it incorporates its own metrics store simplifying the set up and execution of A/B/n and performance tests. Iter8 currently supports the following databases:
+
+- BadgerDB
+- Redis
+
+Iter8 uses BadgerDB by default. Note, however, that BadgerDB is not suitable for prodcution use and is only suitable for a single instance of Iter8. Support for other databases are in the works. See [below](#contribute-a-new-metrics-store-implementation) for details on how to contribute additional implementations.
+
+## Using Redis as the metrics store 
+
+We assume that Redis is deployed. For example, for a basic deployment:
+
+```shell
+kubectl create deploy redis --image=redis/redis-stack:latest --port=6379
+kubectl expose deploy redis --port=6379
+```
+
+Run Iter8 with the metrics store implementation set to `redis` and specify its endpoint:
+
+```shell
+helm upgrade --install --repo https://iter8-tools.github.io/iter8 --version 0.18 iter8 controller  \
+--set clusterScoped=true \
+--set metrics.implementation=redis \
+--set metrics.redis.addresss=redis:6379
+```
+
+## Contribute a new metrics store implementation
+
+To contribute a new metrics store implementation:
+
+1. Create an [issue](https://github.com/iter8-tools/iter8/issues) for discussion.
+
+2. Submit a pull request on the [Iter8 project](https://github.com/iter8-tools/iter8) with the following updates:
+
+    - Create sub-folder in [storage](https://github.com/iter8-tools/iter8/tree/master/storage) and provide an implementation of this [interface](https://github.com/iter8-tools/iter8/blob/master/storage/interface.go) including test cases.
+
+    - Add a new case to [metrics.GetClient()](https://github.com/iter8-tools/iter8/blob/master/metrics/client.go).
+
+    - Update [go.mod](https://github.com/iter8-tools/iter8/blob/master/go.mod) and [go.sum](https://github.com/iter8-tools/iter8/blob/master/go.sum) if needed.
+
+    - Update the default Helm chart configuration [values.yaml](https://github.com/iter8-tools/iter8/blob/master/charts/controller/values.yaml) and bump the chart version in [Chart.yaml](https://github.com/iter8-tools/iter8/blob/master/charts/controller/Chart.yaml).
+
+    - Please also consider including your information in our list of [adopters](https://github.com/iter8-tools/iter8/blob/master/ADOPTERS.md).
+
+3. Submit a second pull request on the Iter8 [docs project](https://github.com/iter8-tools/docs) updating the list of available implementations.
+
+4. Alert the project reviewers on [Slack](https://join.slack.com/t/iter8-tools/shared_invite/zt-awl2se8i-L0pZCpuHntpPejxzLicbmw) `#development` channel.
