① Click on +Add, then on Securities and choose Ordinary share
② Enter the name of the ordinary share
Regarding the name given, refer to your legal documentation. It will necessarily be specified there if it's a security that needs to have a particular title, example: on an A series, it commonly happens that A shares are created.
If you are at the stage of restating your history and incorporating the company, you can simply name your security : Ordinary shares.
③ Enter the date of first issue
⚠️ The share creation workflow allows you to add an acquisition calendar. You can leave this parameter unchecked, as ordinary shares are by definition not concerned.
