 * `Create` a database and table (necessary for the subsequent CRUD operations).
 
     ```bash
-    $ python3 tasks.py create
+    $ python3 src/tasks.py create
     ```
 
 * `Drop` the database (and table).
 
     ```bash
-    $ python3 tasks.py drop
+    $ python3 src/tasks.py drop
     ```
 
 * `Insert` a new tasks record.
 
     ```bash
-    $ python3 tasks.py add 'New Task Description'
+    $ python3 src/tasks.py add 'New Task Description'
     ```
 
 * `Update` a task record's completion field (by specifying the `id` and `completion` value).
 
     ```bash
-    $ python3 tasks.py update 3 1
+    $ python3 src/tasks.py updateStatus 3 1
     ```
 
 * `Select` and print all tasks.
 
     ```bash 
-    $ python3 tasks.py show
+    $ python3 src/tasks.py show
     ```
 
 * `Delete` a task record (by `id`).
 
     ```bash
-    $ python3 tasks.py delete 3
+    $ python3 src/tasks.py delete 3
