+## Adding Capacity with Multiple Licenses
+
+If your server needs more user or site capacity than a single license provides, you can generate and activate additional license keys on the same server instead of purchasing a larger plan. Alternatively reach out to support to update your contract. 
+
+- **Capacity stacks**: The user and site limits from every valid key activated on the server are added together.
+- **Highest tier wins**: Feature access is based on the highest tier among your active keys. For example, activating a Scale-tier key alongside a Starter-tier key unlocks Scale-tier features across the whole server.
+- **Personal keys can't combine with paid keys**: If a paid (non-personal) key is active on the server, any personal-use keys are automatically excluded and stop counting toward capacity.
+
+<Steps>
+<Step title="Generate an additional license">
+  Purchase or generate another license key from [app.pangolin.net](https://app.pangolin.net) — see [Purchase a license key](/self-host/purchase-license-key).
+</Step>
+
+<Step title="Add it to your server">
+  Log in with server admin credentials, open the Server Admin panel, and go to the License section at `/admin/license`. Use **Add** to activate the additional key — it's added alongside your existing key(s) rather than replacing them.
+</Step>
+
+<Step title="Verify combined capacity">
+  The License section shows your combined user and site limits across all activated keys.
