Then, fill in "Apply for TiDB Cloud Premium" in the **Description** field and click **Submit**.

+
+## Steps
+
+If you are in the `Organization Owner` or the `Instance Creator` role, you can create a Premium instance as follows:
+
+1. Log in to the [TiDB Cloud console](https://tidbcloud.com/).At the bottom of the left navigation bar, locate the "Switch to Private Preview" entry and click it to enter the Premium Preview interface. If you cannot see this entry, it might be because your organization has not been invited to the Premium Private Preview yet. In this case, please contact Tech Support.
+
+2. Navigate to the [**TiDB Instances**] page.
+
+3. Click **Create Instance**.
+
+4. Input instance name .
+
+5. Choose a cloud provider and a region where you want to host your instance.
+
+6. Update the capacity of the instance.
+
+    - You must specify both a minimum and maximum number of Request Capacity Units (RCUs) for your instance.
+
+    - RCUs represent the compute resources provisioned for your workload. TiDB Cloud automatically scales your instance within this range based on demand.
+
+7. Click **Create**.
+
+    The instance creation process begins. If this is your first instance in the selected region, provisioning typically takes about 30 minutes. If you already have an existing instance in the region, the process is faster and usually completes within about 1 minute.
+
+## What's next
+
+After your instance is created, follow the instructions in [Connect to TiDB Cloud via Public Endpoint](/tidb-cloud/connect-via-standard-connection-premium.md) to create a password for your instance.
+
+> **Note:**
+>
+> If you do not set a password, you cannot connect to the instance.
