Simple pre-render script with editable text message

Hello guys,

can you please help me with the code for most simple pre-render script with some editable message, that i will be able to edit and change, depending on rendering tasks (just as a personal reminder)? So i need the script to show some message, before each start of the rendering. I don't know if it's important or not here, render engine is finalRedner R3.5, and Max version is 2012 x64 (and 2015 x64).
Ideally it would be possible to mark different text portions in different flashy colors, but this is not crucial to me (maybe something like this already exists?).

I never used pre-render scripts before so i hope this is doable.

Thank you so much for your help in advance...
