## Prerequisites
2+
3+
- Kubernetes 1.9+
4+
- A running Hyperledger Fabric network on kubernetes.
5+
6+
## Installing the Chart
7+
8+
To install the chart with the release name `explorer`:
9+
10+
```bash
11+
$ helm install explorer/ --name explorer
12+
```
13+
14+
The command deploys the Blockchain Explorer & Explorer-DB on the Kubernetes cluster in the default configuration. The [Configuration](#configuration) section lists the parameters that can be configured during installation.
15+
16+
## Test the Chart
17+
18+
To test the chart with the release name `explorer`:
19+
20+
```bash
21+
$ helm test explorer
22+
```
23+
24+
The command tests the Blockchain Explorer & Explorer-DB on the Kubernetes cluster.
25+
26+
## Uninstalling the Chart
27+
28+
To uninstall/delete the `explorer` deployment:
29+
30+
```bash
31+
$ helm delete explorer
32+
```
33+
34+
The command removes all the Kubernetes components associated with the chart and deletes the release.
35+
36+

37+
38+
The following table lists the configurable parameters of the Blockchain Explorer & Explorer-DB chart and default values.
