If anything doesn't work as expected during setup, please refer to the troubleshooting guide.
That said, please read the instructions carefully so as not to miss anything.

1. If you haven't already, download and install Java 17 here.
2. Download the latest release of Entralinked here. You will want to download the file called entralinked.zip.
3. Extract entralinked.zip to a location where it has read & write permissions, such as a folder on your desktop.
4. Run Entralinked by double clicking on entralinked.jar. If prompted, allow it to communicate on both public and private networks. After that, a window should appear; wait for Entralinked to start.
5. Entralinked should tell you to input a custom DNS server into your DS. Navigate to the internet settings of your DS and input the DNS as your primary DNS in your active connection. Make sure there are no other connections configured, as they may cause interference. If you perform a connection test and it fails, it does not matter.
6. Start your game and use Game Sync through the C-Gear. If all is well, it should allow you to tuck in a Pokémon.
7. After tucking in a Pokémon, navigate to the user dashboard and log in with your Game Sync ID.
   Choose whatever content you want to download to your game and wake up your Pokémon after saving your profile.
