How do I output or echo NONE if grep does not find anything?

I am performing a grep command and I need to know how to echo "NONE" or "0" to my file if grep does not find what i am looking for.

echo What i found >> My_File
grep "SOMETHING" >> My_File

I am sure this is easy, I am sort of new at this!

Thanks

Code:
grep -c "SOMETHING" file >> My_File
-c is the count. If the pattern doesn't exist then it will display 0.

If you want to output NONE then the below will help you

Code:
grep -c "SOMETHING" file | sed 's/0/NONE/' >> My_File
