At your Numberish dashboard, click the + sign behind the Todos item from left menu. Or at the work area of the dashboard itself, click the + Add New option. Then choose Todos as card type.
Give the card a name. This name is also used as hashtag to uniquely identify a Numberish card. Use letters and numbers only. No spaces or other special characters are allowed.
Also give this card a good description so that you and others can find this card, and understand the meaning.
Then below it, you can enter your first item or thing for your todo. Enter the name. For example: add cake to your shopping list. Click the plus button to add more items to this list. Did you made a mistake or do you want to remove an item from the list, then click the red x button. When you have completed a todo item, then just check the item entry and it will strikethru the name.
Finally you can declare this card as a public or private card. Public cards and values can be found, seen and followed by others. While private cards, are for you and you only.
Click the Save button to commit your changes.
At this point, we can see the Numberish card in runtime mode. With that view, you can see the items that are still on the list. Click the edit icon to open and manage your todo list.
Any change here will be written back to the Numberish database, and visible to all others using and following this card.
