-# helm-chart-version
-Bump Helm Chart version on local filesystem (golang port of github.com/shaneramey/helm-local-bump)
+# Helm Chart Version Plugin
+
+This is a Helm plugin that helps you change your chart version.
+It is meant to be used in integration pipelines.
+
+## Usage
+
+```
+helm local-chart-version [subcommand] [PATH_TO_LOCAL_CHART] [flags]
+```
+
+know more: 
+```
+helm local-chart-version help
+```
+
+## Install
+
+### Using Helm plugin manager (> 2.3.x)
+
+```shell
+helm plugin install https://github.com/mbenabda/helm-local-chart-version
+```
+
+### Pre Helm 2.3.0 Installation
+Pick a release tarball from the [releases](https://github.com/mbenabda/helm-local-chart-version/releases) page.
+
+Unpack the tarball in your helm plugins directory (`$(helm home)/plugins`).
+
+E.g.
+```
+curl -L $TARBALL_URL | tar -C $(helm home)/plugins -xzv
+```
+
+## Build
+
+Clone the repository into your `$GOPATH` and then build it.
+
+```
+$ mkdir -p $GOPATH/src/github.com/mbenabda/
+$ cd $GOPATH/src/github.com/mbenabda/
+$ git clone https://github.com/mbenabda/helm-local-chart-version.git
+$ cd helm-local-chart-version
+$ make install
+```
+
+The above will install this plugin into your `$HELM_HOME/plugins` directory.
+
+### Prerequisites
+
+- You need to have [Go](http://golang.org) installed. Make sure to set `$GOPATH`
+- If you don't have [Glide](http://glide.sh) installed, this will install it into
+  `$GOPATH/bin` for you.
+- install [github.com/c4milo/github-release](https://github.com/c4milo/github-release)
