+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# `@metamask/transaction-details-insights-example-snap`
+
+This snap demonstrates how to use the `endowment:transaction-details-insight` permission
+to provide historical transaction insights to the user. This snap uses the `onTransactionDetails`
+handler to provide insights for *past* user transactions.
+
+Activity item insights are displayed in the transaction details modal, and
+can show any [Snaps-based UI](../../../snaps-sdk) components.
+
+## Snap manifest
+
+> **Note**: Using `onTransactionDetails` requires the `endowment:transaction-details-insight`
+> permissions. Refer to [the documentation](https://docs.metamask.io/snaps/reference/permissions)
+> for more information.
+
+Along with other permissions, the manifest of this snap includes the
+`endowment:transaction-details-insight` permission:
+
+```json
+{
+  "initialPermissions": {
+    "endowment:transaction-details-insight": {}
+  }
+}
+```
+
+By default, the `onTransactionDetails` does not receive the transaction origin. If you
+want to receive the origin, you can add the `allowTransactionDetailsOrigin` property to
+the permission definition:
+
+```json
+{
+  "initialPermissions": {
+    "endowment:transaction-details-insight": {
+      "allowTransactionDetailsOrigin": true
+    }
+  }
+}
+```
+
+## Snap usage
+
+This snap exposes an `onTransactionDetails` handler, which is called when a transaction details modal is opened by a user. The handler receives the transaction details and the
+transaction origin (if the `allowTransactionDetailsOrigin` property is set to `true`).
+
+The snap simply takes the details about the transaction and displays them. In practice a real Snap may want use transaction details to fetch insights from a remote server and display them to the user.
+
+For more information, you can refer to
+[the end-to-end tests](./src/index.test.ts).
