+You will need to compile this code to run it. A compiled version for Windows is included on the release page of Github. If you are going to compile it yourself with `gcc`, then you will need the `-std=c99` option (e.g., command like “gcc -o mendeleyBibFix mendeleyBibFix.c -std=c99”).
 
-Call syntax (windows):
- 		mendeleyBibFix.exe [OUTPUT_FILENAME] [INPUT_FILENAME]
+The full call syntax is as follows:

+* Call syntax (Linux or macOS):
+ 		`./mendeleyBibFix [OUTPUT_FILENAME] [INPUT_FILENAME]`
 
-Both arguments are optional. If there is only one argument, then it is assumed to be the output filename.

+You can run the script in one of two ways:
+1) Open a command window and navigate to the folder containing both the bib-file and the executable (e.g., cd "C:\Users\Documents..."). Then enter (for Windows) "mendeleyBibFix.exe OUTPUT_FILENAME INPUT_FILENAME". You can omit the filename arguments if your bib-file is called library.bib and you want the script to create library_fixed.bib.
+2) If you're happy with the default arguments, and if the executable is placed in the same directory as the bib-file "library.bib", then you can just double-click on the executable
