+
+## Add a board with the Boards Manager
+
+Official Arduino cores can be conveniently installed with the Boards Manager tool.
+
+1. In the menu bar, select _Tools > Board > Boards Manager_. In IDE 2.x you can also access it by clicking the button in the left-most sidebar.
+
+2. Either search for the package name (e.g. "megaAVR"), or the board (e.g. "Uno", "MKR1000", or "Portenta"), by typing in the search field.
+
+3. Find the package that includes your board.
+
+4. Click **Install** (the latest version is selected by default).
+
+   > If the package is already installed, you will instead have the option of installing a different version.
+
+5. Wait for the installation to complete.
