 ### Step 5. Compile the sketch
 To compile the sketch we have to run the `compile` command with the proper FQBN we just got in the previous command.

 #### How can I find the core/FQBN for a board?
 
-You must first find the core, for example if you are interested in the Arduino Zero you can search the term `zero`:
-
-```
-$ arduino-cli core search zero
-Searching for platforms matching 'zero'
-
-ID          	Version	Name
-arduino:samd	1.6.19 	Arduino SAMD Boards (32-bits ARM Cortex-M0+)
-```
-
-once the core is determined you should install it with `arduino-cli core install arduino:samd` and, once installed, you can connect the board and detect it with `arduino-cli board list`.
-
-If the board is not detected for any reason, you can list all the supported boards with `arduino-cli board listall` and also search for a specific board, in our example `arduino-cli board listall zero`.
