**Create Segments**

Learn how to create segments to define reusable groups of users.

[Do this via the API →](/docs/reference/api/how-to-guides/flags/create-segment.md)

A [segment](/docs/capabilities/segments/overview) is a definition of a subpopulation, like a certain cohort
of users.

## Create a Segment

**1. Navigate to Segments**

Select **Segments** in the left sidebar.

**2. Click + Create to create a new segment**

**3. Give the segment a name**

The name can't be changed later, so choose wisely.

**4. Define the inclusion criteria**

Define the inclusion criteria for the segment by clicking **+ Add attribute**, **+ Add segment**, or **+ Add group** in the **Inclusion criteria** section. You can add multiple criteria.

**5. Set the allocation of the segment to the desired percentage**
