 ### Footnotes
 
+#### Check for all possible issues
+
+The script named `check-all.sh` is to be used to check the sources for all detectable errors and issues. This script can be run w/o any arguments:
+
+```
+./check-all.sh
+```
+
+Expected script output:
+
+```
+Running all tests and checkers
+  Check all BASH scripts
+    OK
+  Check documentation strings in all Python source file
+    OK
+  Detect common errors in all Python source file
+    OK
+  Detect dead code in all Python source file
+    OK
+  Run Python linter for Python source file
+    OK
+  Unit tests for this project
+    OK
+Done
+
+Overal result
+  OK
+```
+
+An example of script output when one error is detected:
+
+```
+Running all tests and checkers
+  Check all BASH scripts
+    Error: please look into files check-bashscripts.log and check-bashscripts.err for possible causes
+  Check documentation strings in all Python source file
+    OK
+  Detect common errors in all Python source file
+    OK
+  Detect dead code in all Python source file
+    OK
+  Run Python linter for Python source file
+    OK
+  Unit tests for this project
+    OK
+Done
+
+Overal result
+  One error detected!
+```
+
+Please note that the script creates bunch of `*.log` and `*.err` files that are temporary and won't be commited into the project repository.

 #### Coding standards
 
 - You can use scripts `run-linter.sh` and `check-docstyle.sh` to check if the code follows [PEP 8](https://www.python.org/dev/peps/pep-0008/) and [PEP 257](https://www.python.org/dev/peps/pep-0257/) coding standards. These scripts can be run w/o any arguments:
