If you want to exclude source files from the build (for example, to exclude the arduino\_core, Sloeber will take care to include the core files via its integrated board manager!), right click on that folder in the tree view on the left, go to Resource Configureation and configure Exclude from Build.

+	- Install all required board libraries by going to Arduino &rarr; Preferences and using the options Library Manager and Platform and Boards.
+	- It is necessary to install the `arduino-timer` library by searching for timer in the Library Manager. 
+	- It is recommended to install the Arduino AVR Boards and the Arduino megaAVR Boards in the Platforms and Boards manager. 
+	- It is also necessary to go to Arduino &rarr; Preferences &rarr; Add a library to the selected project and then adding the `arduino-timer` and `SPI` library there.

 ### Build and flash instructions
 
-1. An Arduino like bar can be seen at the top, which can be used to compile the software and flash it to the board. The check symbol is used to compile while the right arrow symbol is used to flash the software. There are also symbols to open the serial monitor or the serial plot.
+1. Right click on the arduino folder inside the tree view on the left and go to Preferences.
+Go to the Arduino section and make sure the Arduino Board Selection tab is configured correctly.  
+Please note that board libraries and libaries need to be installed and added as beforehand as specified in Prerequisites.
+It is recommended to go to the Compile Options tab and addding following define to `to append to C and C++`
 
-2. The serial monitor can be opened in the Serial monitor view tab at the bottom or with the icons at the top bar. Take care to pick the correct USB port and baud rate.
