-===== Common commands =====
+**idf.py** to be invoked as:
-  idf.py --version
+```
-  idf.py help
+$ idf.py <parameters>
-  idf.py fullclean
+```
-  idf.py menuconfig
+**esptool** can be invoked in different ways:
-  idf.py build
+```
+$ esptool <parameters>
-===== Full Flash =====
+$ python -m esptool <parameters>
-  idf.py -p /dev/ttyACM0 flash
+```
