Application notes lets you try out features, hone your Blocks skills and learn best practice. Follow these general steps to use most application notes:

1. Download a .zip file containing the application note files.
2. Unzip it to a directory of your choice.
3. Stop Blocks if it is running.
4. Make sure you have a file named PIXILAB-Blocks-config.yml in your home directory, containing your preferred Blocks settings, as described here.
5. Locate or create a root entry in that configuration file, specifying the path to the application note directory unzipped in step 2 above, as described here.
6. Start Blocks.

If you don't already have a configuration file in your home directory, you can download this generic configuration file.

To open a test display spot using your computer's browser with a server running on the same computer, use the standard Blocks spot url:

http://localhost:8080/spot

If you need more that one display spot, a query parameter can be addad to the URL like this:

http://localhost:8080/spot?display=1

You can add any number of "fake displays" in this way. Make sure all the browser windows use display numbers, or the spot/window will misbehave (indicated by the connection status indicator of the display spot flashing in the editor).

Replace localhost:8080 with your server's IP or domain name if the server is accessed over the network.

You must most likely reassigned any Display Spots used in the application note to your fake display windows by double clicking the Display Spot in the editor and selecting your spot's ID under "Re-assign to Spot ID".
