+Having symbolic links may cause an infinite loop. There is an option to disable them altogether though.
 
 If original directory to count is ~/u, and ~/u/v is a symbolic link to ~/v, and ~/v/x/y is a symbolic link to ~/v, there will be a loop.
 
 However, if all symbolic links to the files in the same directory, then there will be no infinite loop, and no file is counted twice.
+## Examples
+```
+csloc -qt folder -x h c
+```
+Count all the .h and .c files in folder, and display each file's counts, sorted greatest to least.
+```
+csloc -fr folder -x hpp cpp
+```
+Count all the .hpp and .cpp files in folder, and display the file size of each file, sorted least to greatest, with complete sentences.
