+Here, you can also provide some information regarding the type of arduino, and which code you'd like to compile. 
+
 ### 2. Select your board to compile with. As I always forget which boards to select, here's my cheat sheet:
 
 | Arduino  | Board |
 | ------------- | ------------- |
 | ArduinoWifi | LOLIN(WeMos) D1 R1 |
-| ... | ... |
+| ESP32 DEVKITV1 | DOIT ESP DEVKIT V1 |
+
+
 
-### 3. Do something with the make files
 
-  arduino-cli compile -b arduino:avr:uno --build-property "build.extra_flags=\"-DMY_DEFINE=\"hello world\"\"" /home/user/Arduino/MySketch
