# Comments in protection tables

Protection tables can be difficult to interpret and debug. Including comments can make this work much easier.

- You can append comments at the end of a line using the `##` symbols:

      write user *   10.1.1.1   //depot/test/...  ## robinson crusoe

- Or you can write a comment line by prefixing the line with the ## symbols:

      ## robinson crusoe
      write user *   10.1.1.1   //depot/test/...

Comments you have created using the P4 Admin tool are not compatible with comments created using the 2016.1 version of `p4 protect`. You can use the following command to convert a file containing comments created with P4 Admin into a file containing `p4 protect` type comments:

    $ p4 protect --convert-p4admin-comments -o

Then save the resulting file.
