+_Note, there is an exception where by the veBAL page is still available at
+[https://app.balancer.fi/vebal](https://app.balancer.fi/vebal). We will continue to maintain the veBAL page of this

-## Self-Hosting
-
-As we believe in decentralization at all layers, we've made it easy to host your own Balancer Frontend.
-
-### Docker Production Image
-
-We've created a production ready [docker image](./Dockerfile) runs
-a pre-built version of Balancer Frontend-v2 using nginx. You'll need your own
-[Infura](https://infura.io), [Alchemy](https://www.alchemy.com/), and
-[Blocknative](https://blocknative.com) API keys in order to fetch data and
-execute transactions.
-
-Here's an example of how to run the container. This can also be found in [scripts/run-docker.sh](./scripts/run-docker.sh).
-
-```bash
-docker run \
-  -e INFURA_PROJECT_ID=   \ # Required
-  -e ALCHEMY_KEY=         \ # Required
-  -e BLOCKNATIVE_DAPP_ID= \ # Required
-  balancerfi/frontend-v2
-```
-
-### Custom RPC urls
-
-To override RPC network config set in `src/lib/config`, you can use the following environment variables:
-
-`VITE_RPC_URL_<networkId>=XXX`
-
 ### One Click Deploys
 
 The frontend can easily be deployed to any static host. Use the buttons below to spin up an instance. You will be prompted to provide your Infura Project ID, Alchemy Key, and Blocknative Dapp ID as these are required for the frontend to work correctly.
