+## Dialog modals
+
+Dialog modals are only used for having a conversation and confirmation with the user. The user is not able to access the features on the main page until closing the modal.
+
+### Usage
+
+* When the action is irreversible, dialog modals provide the details and confirm with the user before they take an advanced action.
+* When the action will affect privacy or authorization, dialog modals provide advanced information and confirm with the user.
+
+### Style
+
+* Dialog modals contain the header, body, and actions.
+  * **Header(1):** The header title is a question instead of a descriptive phrase.
+  * **Body(2):** The content in body should never be ambiguous and unclear. It provides specific information.
+  * **Actions(3):** Contains a affirmative action, a dismissive action, and an extra action. The order of actions from left to right: Dismissive action → Extra action → Affirmative action
+* Confirmations regarding labels should keep labeling styling.
+* References to commits, branches, and tags should be **monospaced**.

+
+### Placement
+
+* Dialog modals should always be the center of the screen horizontally and be positioned **72px** from the top.
