+# Omni Omega Testnet
+
+:::warning 🚧 Under Construction 🚧
+
+The Omni Omega Testnet is currently under construction. Please check back soon for more information, values are placeholders and will be updated soon.
+
+:::
+
+During the Omni Omega Testnet, users will be able to delegate restaked **\$ETH** to the Omni Operators and take part in challenges posted in a site soon to be released.
+
+## Delegating Holesky \$ETH
+
+You can delegate testnet **\$ETH** to securing Omni through EigenLayer through the EigenLayer dashboard. Once there you can:
+
+1. Have Holesky as a network to your browser wallet, funded with Holesky **\$ETH**. [Read more on how here](https://www.coingecko.com/learn/holesky-testnet-eth).
+2. Swap Holesky **\$ETH** for any of the [EigenLayer supported restaking tokens](https://docs.eigenlayer.xyz/eigenlayer/restaking-guides/restaking-user-guide/stage-2-testnet/obtaining-testnet-eth-and-liquid-staking-tokens-lsts).
+3. Connect your wallet to the EigenLayer dashboard.
+4. Restake your restaking tokens to any of the Omni Operators.
+5. 🎉 You are helping secure the Omni Omega Testnet! 🎉
+
+## Adding the Omni Network to Your Wallet
+
+To add the Omni network to your wallet, you can go to the settings for adding a new network of your wallet and add the following information:
+
+- **Network Name**: Omni Omega Testnet
+- **RPC URL**: `$OMNI_TESTNET_RPC_URL$`
+- **Chain ID**: `$OMNI_TESTNET_CHAIN_ID$`
+- **Symbol**: `$OMNI`
+- **Block Explorer URL**: `$OMNI_TESTNET_EXPLORER_URL$`
+
+Alternatively, you can follow a tutorial like the [Metamask Adding a Custom Network Tutorial](https://metamask.zendesk.com/hc/en-us/articles/360043227612-How-to-add-a-custom-network-RPC-and-or-Block-Explorer) to add the Omni Omega Testnet network to your wallet.
+
+## Omni Omega Testnet Explorer
+
+The Omni Omega Testnet Explorer will be published soon. Stay tuned for more information!
