 ### Update Slack Web API
 
 Slack Web API is updated from https://github.com/slack-ruby/slack-api-ref, a maintained, machine-readable version of Slack API Docs, generated by scraping [api.slack.com](https://api.slack.com). To update the Web API from the latest definition run the following Rake task.
 
 ```
-rake slack:api:update
+bundle exec rake slack:api:update
 ```
 
 #### Patching Slack Web API
 
 Sometimes it's necessary to patch auto-generated Slack Web API methods. For example, we want to help clients with calling `to_json` on the `attachments` parameter sent to `chat_postMessage`. See [#20](https://github.com/slack-ruby/slack-ruby-client/issues/20).
