 # Ember-cli-deploy-slack
 
-This README outlines the details of collaborating on this Ember addon.
+An ember-cli-deploy-plugin for sending deployment messages to [Slack](https://slack.com/).
 
-## Installation
+## Usage
 
-* `git clone` this repository
-* `npm install`
-* `bower install`
+This plugin will only work with the upcoming 0.5.0-release of
+[ember-cli-deploy](https://github.com/ember-cli/ember-cli-deploy). Right now
+you have to use my [didFail branch](levelbossmike/ember-cli-deploy#didFail-hook-).
 
-## Running
+To setup ember-cli-deploy-slack you need to add a `slack`-entry into your
+`deploy.js` configuration file:
 
-* `ember server`
-* Visit your app at http://localhost:4200.
+```js
+module.exports = function(environment) {
+  var environments = {
+    "development": {
+      // ...
+      "slack": {
+        "webhookURL": "https://hooks.slack.com/services/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",
+        "channel": "#notifications",
+        "username": "ember-cli-deploy"
+      },
+      // ...
+    },
 
-## Running Tests
+    "staging": {
+      // ...
+    },
 
-* `ember test`
-* `ember test --server`
+    "production": {
+      // ...
+    }
+  };
 
-## Building
+  return environments[environment];
+};
+```
 
-* `ember build`
+## Customization
 
-For more information on using ember-cli, visit [http://www.ember-cli.com/](http://www.ember-cli.com/).
+`ember-cli-deploy-slack` will send default messages on the `didDeploy`- and
+`didFail`-hooks on the pipeline. Because every team is different and people
+tend to customize their automatic slack notifications messages can be
+customized.
+
+To customize a message you simply add a function to your slack configuration
+options that is named the same as the hook notification you want to customize:
+
+```js
+module.exports = function(environment) {
+  var environments = {
+    "development": {
+      // ...
+      "slack": {
+        "webhookURL": "https://hooks.slack.com/services/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",
+        "channel": "#notifications",
+        "username": "ember-cli-deploy",
+        "didDeploy": function(context, slack) {
+          return slack.notify({
+            text: 'w00t I can haz custumizations!'
+          });
+        }
+      },
+      // ...
+    },
+```
+
+
+Notification hooks will be passed the deployment context and the slackNotifier
+utility class. The SlackNotifier uses [node-slackr](https://github.com/chenka/node-slackr) under the hood so you can use its `notify`-function accordingly. This enables you to customize your messages in any way possible. You can even add custom properties to the deployment context if that's what you need to do.
+
+Please see the [Slack API documentation for message formatting](https://api.slack.com/docs/formatting)
+to see how you can customize your messages.
+
+### Available hooks
+
+`willDeploy`, `willBuild`, `build`, `didBuild`, `willActivate`, `activate`,
+`didActivate`, `didDeploy`, `didFail`
