# Add a milestone

A milestone is a significant point on a [multi-stage project](https://doc.sitecore.com/ch/en/users/content-hub/multi-stage-projects.html "Multi-stage projects") timeline, used to evaluate progress. There are two types of milestone:

- **Fixed date milestone** - a standard milestone with a fixed date and no direct relationship with other milestones.
- **Child milestone** - a milestone that is linked to other milestones and is not considered complete until those linked milestones are also completed.

As shown in the following example, a milestone is represented by a diamond.

You can add multiple hierarchy levels to the multi-stage project structure by including a linked milestone, which is a milestone that is connected to other predecessor or successor stages/milestones. A milestone's completion depends on the predecessor stage's completion.

To add a milestone:

1. On the menu bar, click **Project** > **Projects**.
2. On the **Projects** page, select the multi-stage project to which you want to add a milestone.
3. On the **Timeline** tab, do one of the following:
    - To add a fixed milestone, click **New** and select **Milestone**.
    - To add a child milestone, next to the stage where you want to add the milestone, click **More actions** :mdiDotsHorizontal: and select **Add linked milestone**.
4. In the dialog that displays, enter the following details:
    - **Name** - the name of the milestone. This field is required.
    - **Start Date** - the milestone state. Click the date picker [date picker](https://mss-p-003-delivery.stylelabs.cloud/api/public/content/13b1b9529744437badc047705d0b7d67?v=28ada6ce) or enter a date.

    The fields in the **Options** section are relevant only to stages.

5. Click **Create**.
