+# ucentralgwui
+
+> Application description placeholder
+
+## TL;DR;
+
+```bash
+$ helm install .
+```
+
+## Introduction
+
+This chart bootstraps an ucentralgwui on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install --name my-release stable/ipfs
+```
+
+The command deploys ucentralgwui on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```bash
+$ helm delete --purge my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following table lists the configurable parameters of the Memcached chart and their default values.
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+|||
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install --name my-release \
+  --set replicaCount=1 \
+    .
+```
+
+The above command sets that only 1 instance of your app should be running
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```bash
+$ helm install --name my-release -f values.yaml .
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml) as a base for customization.
