 To confirm that your validator is live and synchronized with the Polkadot network, visit the [Telemetry](https://telemetry.polkadot.io/#list/Polkadot%20CC1){target=\_blank} page. Telemetry provides real-time information on node performance and can help you check if your validator is connected properly. Search for your node by name. You can search all nodes currently active on the network, which is why you should use a unique name for easy recognition. Now, confirm that your node is fully synced by comparing the block height of your node with the network's latest block. Nodes that are fully synced will appear white in the list, while nodes that are not yet fully synced will appear gray.
 
-In the following example, a node named `techedtest` is successfully located and synchronized, ensuring it's prepared to participate in the network:

 ### Activate using Polkadot.js Apps
 
 Follow these steps to use Polkadot.js Apps to activate your validator:
 
-1. Go to the **Validator** tab in the Polkadot.js Apps UI and locate the section where you input the keys generated from `rotateKeys`. Paste the output from `author_rotateKeys`, which is a hex-encoded key that links your validator with its session keys:

 2. Set a reward commission percentage if desired. You can set a percentage of the rewards to pay to your validator and the remainder pays to your nominators. A 100% commission rate indicates the validator intends to keep all rewards and is seen as a signal the validator is not seeking nominators.
 
 3. Toggle the **allows new nominations** option if your validator is open to more nominations from DOT holders.
 
 4. Once everything is configured, select **Bond & Validate** to activate your validator status.

 5. Edit the **commission** and the **blocked** option via `staking.validate` extrinsic. By default, the blocked option is set to FALSE (i.e., the validator accepts nominations).

 ### Monitor Validation Status and Slots
 
 On the [**Staking**](https://polkadot.js.org/apps/#/staking){target=\_blank} tab in Polkadot.js Apps, you can see your validator's status, the number of available validator slots, and the nodes that have signaled their intent to validate. Your node may initially appear in the waiting queue, especially if the validator slots are full. The following is an example view of the **Staking** tab:
 
-![staking queue](/images/infrastructure/running-a-validator/onboarding-and-offboarding/start-validating/start-validating-05.webp)
+![staking queue](/images/infrastructure/running-a-validator/onboarding-and-offboarding/start-validating/start-validating-03.webp)
 
 The validator set refreshes each era. If there's an available slot in the next era, your node may be selected to move from the waiting queue to the active validator set, allowing it to start validating blocks. If your validator is not selected, it remains in the waiting queue. Increasing your stake or gaining more nominators may improve your chance of being selected in future eras.
