Here is a list of placeholders needed for the embeds

To generate yourself the customJSON value, do the following:

• If you are done, select “JSON representation” in the drop down on the right and copy the output below.
• In case you need to, paste this into notepad (or similar) and replace values with the placeholders, then copy everything again
• “Escape” the code you have using this website.
• Paste the escaped code into the customJSON config
• The config entry should look like this:

To start from scratch, click \\\"Clear all\\\" at the top.\"\r\n  }\r\n}"
