+## Counting number of lines of codes
+
+It might be useful at some point to count the number of lines of code in a given project.
+[Cloc](https://github.com/AlDanial/cloc) is an open-source tool that counts blank lines, comment lines, and physical lines of source code in many programming languages. 
+
+In [Pinocchio](https://github.com/stack-of-tasks/pinocchio), counting the important lines of code can be done using:
+
+```bash
+cloc unittest src include examples bindings 
+```
+
+which gives:
+```
+    3149 text files.
+    2299 unique files.                                          
+     970 files ignored.
