 # CloudApp plugin
 
+## The CloudApp API is deprecated, so the plugin will be removed shortly
+
 [CloudApp](https://www.getcloudapp.com) brings screen recording, screenshots, and GIF creation to the cloud, in an easy-to-use enterprise-level app. The CloudApp plugin allows you to upload a file to your CloadApp account from the command line.
 
 To use it, add `cloudapp` to the plugins array of your `~/.zshrc` file:

plugins/cloudapp/cloudapp.plugin.zsh

-alias cloudapp="${0:a:h}/cloudapp.rb"
-
-# Ensure only the owner can access the credentials file
-if [[ -f ~/.cloudapp ]]; then
-  chmod 600 ~/.cloudapp
-fi
+print -Pn "%F{yellow}"
+print "[oh-my-zsh] The CloudApp API no longer works, so the cloudapp plugin will"
+print "[oh-my-zsh] be removed shortly. Please remove it from your plugins list."
+print -Pn "%f"
