 If you want to run Cosmos DB Explorer alongside Cosmium, you'll need to build it yourself and point the `-ExplorerDir` argument to the dist directory. Please refer to the [Cosmos DB Explorer repository](https://github.com/Azure/cosmos-explorer) for instructions on building the application.
 
+There's also a prebuilt docker image that includes the explorer: `ghcr.io/pikami/cosmium:explorer`

 Once running, the explorer can be reached by navigating following URL: `https://127.0.0.1:8081/_explorer/` (might be different depending on your configuration).
