Setting in dialog box of node repository in mining

Hello

Whenever I select a node from mining and try toconfigure it ,then a dialog box open with three files namely Options,Memory Policy and Flow Variables.I can't understand what to set in these specific fields.

As a beginner, just ignore the Memory Policy and Flow Variables tabs. Everything else is explained in the description of the node. You can access this description with the small Button with a Question Mark on it in the lower right of this dialog, or read it directly without opening the dialog by just selecting the node.
