-😀 GOOD NEWS: If you are not a power user and don't want to bother remembering PytubePP Commands! (You are not familier with Command Line Tools). We recently released a Browser Extension that can auto detect YouTube Videos and You can download the Video in one click directly from the browser using PytubePP CLI. Install [PytubePP Helper](https://github.com/neosubhamoy/pytubepp-helper) app in your System and add [PytubePP Extension](https://github.com/neosubhamoy/pytubepp-extension) in your Browser to get started.

 ### **📌 Commands and Flags**
 Using PytubePP is as simple as just supplying it only the YouTube video url as argument!
-** Before Starting Please NOTE: PytubePP follows a simple rule - "Use the Default Download Configuration if No Flags are Passed"
+> Before starting please NOTE: PytubePP follows a simple principle -> `Use Default Configuration if No Flags are Passed`
 * To download a video in default configuration (maximum resolution and without any caption by default) the command will look like:
 ```terminal
 pytubepp "https://youtube.com/watch?v=2lAe1cqCOXo"
 ```
+> NOTE: This command will behave differently if you have changed default configurations
 * To download the video in a specific resolution (suppose 480p) the command will be:
 ```terminal
 pytubepp "https://youtube.com/watch?v=2lAe1cqCOXo" -s 480p
 ```
+> NOTE: PytubePP always uses default configuration of flags if they are not passed for example if you only pass `-s` flag then it will use the default caption along with it, if you only pass `-c` then it will use default stream and vice versa
 * To download the video with embeded caption (suppose en - English) the command will be:
 ```terminal
 pytubepp "https://youtube.com/watch?v=2lAe1cqCOXo" -c en
 ```
+> NOTE: You can override and disable default caption for the current video if you pass `-c none`
 * To download the video in audio-only MP3 format the command will be:
 ```terminal

If You set default stream then next time when you download, You don't need to pass the `-s 1080p` flag, just pass the video url and it will auto select the `1080p` stream by default).
