Appium doctor verifies that all dependencies required for starting the Appium server are there or not.
In simple words it checks whether the node.js, JAVA, Android SDK are installed on the system( more specifically the environment variable of these are setup)


If all green you have setup the Appium properly.

For the above stat of Appium Doctor you are good to go with iOS testing but you have to fix the error before you can proceed with android.
