 ErieCanal is an implementation of [Kubernetes Multi-Cluster Service API (MCS)](https://github.com/kubernetes-sigs/mcs-api) that depends on a service mesh and Ingress to provide service registration and discovery capabilities across k8s clusters. When using ErieCanal as an MCS provider, it must be used in conjunction with [osm-edge](https://github.com/flomesh-io/osm-edge), which provides east-west traffic flow capabilities, while ErieCanal provides north-south traffic flow capabilities. ErieCanal also provides the ability to register and discover services across clusters. In the MCS multi-cluster mode, ErieCanal currently supports three traffic modes for Kubernetes clusters that join the ClusterSet: `Locality`, `Failover`, and `ActiveActive`. 
 
-In the `Locality` mode, which is the default configuration, traffic is scheduled based on proximity within the local cluster or can be scheduled to a specific cluster based on topology.In the `ActiveActive` mode, the cluster provides the same traffic processing capabilities as service export (`ServiceExport`) using load balancing. In the `Failover` mode, the importing service (ServiceImport) cluster provides disaster recovery capabilities for the exporting service (ServiceExport) cluster. ErieCanal's implementation does not require the underlying Kubernetes to use a special network and does not require a unified two-layer or three-layer network between the multi-cluster networks. Therefore, it is generally applicable to Kubernetes clusters of various types of networks.

+## Install
+
+This chart bootstraps a ErieCanal deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+### Prerequisites
+
+- Kubernetes 1.19+
+
+### Installing the Chart
+
+To install the chart with the release name `erie-canal` run:
+
+```bash
+$ helm repo add erie-canal https://flomesh-io.github.io/ErieCanal
+$ helm install erie-canal erie-canal/erie-canal --namespace erie-canal --create-namespace --version=0.1.0-alpha.1
+```
+
+The command deploys ErieCanal on the Kubernetes cluster using the default configuration in namespace `erie-canal` and creates the namespace if it doesn't exist. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+As soon as all pods are up and running, you can start to evaluate ErieCanal.
+
+### Uninstalling the Chart
+
+To uninstall the `erie-canal` deployment run:
+
+```bash
+$ helm uninstall erie-canal --namespace erie-canal
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+### Configuration
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install erie-canal erie-canal/erie-canal --namespace erie-canal --create-namespace --version=0.1.0-alpha.1 \
+  --set ErieCanal.image.pullPolicy=Always
+```
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```bash
+$ helm install erie-canal erie-canal/erie-canal --namespace erie-canal --create-namespace --version=0.1.0-alpha.1 -f values-override.yaml
+```
