Skip all the questions during installation without filling out any fields.

After installation is finished, navigate to the Obol Package and click on the tab BACKUP.

Click "Backup Now", which will download a file with a `.tar.xz` ending. Expand the file and you should see the following contents.

Delete all files from the `charon1` directory. Now expand the keyshare file you received from ether.fi and put all the contents into the `charon1` directory.

Open the `cluster-lock.json` file and find the `operators` array and find your operator entry. The file you received will have the number of your node in the cluster. Keep in mind that the first node is node0, so node3 would be the fourth operator in the array for example.

Next, create a file called `enr` (just `enr` without a file ending).&#x20;

Open the `enr` file in a text editor and paste your enr text from the operator array in the `cluster-lock.json`. Save the file and exit.

Your contents should now look like the following:

Only `charon1` has changed. The other folders have to stay unchanged.

Now you have to pack all the charon folders back to a `.tar.xz` file. This is different on all OSs but on Linux and macOS, you can do the following in the Terminal:

```
cd directory-with-charon-folders
tar -cvf obol-backup.tar ./
xz obol-backup.tar
```

On macOS you might need to install the xz package with Homebrew: <https://formulae.brew.sh/formula/xz>

After those commands, you should see an `obol-backup.tar.xz`. You will need it in the next step.

Open the Dappnode interface again and go to packages. Make sure to start the package "Holesky Obol", as the containers should be stopped right now. You need to be fast with the next step, as otherwise the Obol package will exit again and you need to start it again before continuing.

Next, navigate to the Obol packages Backup tab.

Click "Restore" and select your `obol-backup.tar.xz` you created just before. Restore from this file.

This should be it. If you notice any errors during Restore, start the obol package again and click restore again. It takes a few tries sometimes to get it right.

You can now check your Logs now and tell ether.fi that you finished the process.

And that should be it! The keyshare has been imported into your Holesky Obol Charon client and once your Testnet Holesky chains are synced, the validator will start to perform its duties 🥳
