 Use `mbed add` to add the latest revision of a library:
 
 ```
-$ mbed add https://developer.mbed.org/users/wim/code/TextLCD/

 Use the `URL#hash` format to add a library from a URL at a specific revision hash:
 
 ```
-$ mbed add https://developer.mbed.org/users/wim/code/TextLCD/#e5a0dcb43ecc
+$ mbed add https://os.mbed.com/users/wim/code/TextLCD/#e5a0dcb43ecc

 #### Specifying a destination directory
 
 If you want to specify a directory to which to add your library, you can give an additional argument to ``add``, which names that directory. For example, If you'd rather add the previous library in a directory called "text-lcd" (instead of TextLCD):
 
 ```
-$ mbed add https://developer.mbed.org/users/wim/code/TextLCD/ text-lcd
+$ mbed add https://os.mbed.com/users/wim/code/TextLCD/ text-lcd
 ```
 
 Although Mbed CLI supports this functionality, we don't encourage it. Adding a library with a name that differs from its source repository can lead to confusion.
