+## Minikube
+
+### Start Minikube
+Disk allocation is done by the driver used to create the VM. Setting this to a high value will do nothing if the
+driver isn't correctly configured. You'll only notice that hydroflow runs out of disk space while compiling.
+For Docker, the disk size is set in the Docker Desktop settings. Also, provide as many CPUs here as possible, since 
+building the code is CPU-intensive.
+```shell
+minikube start --disk-size=100g --cpus=16 --memory=32768
+```
+
+### Use the Docker daemon from minikube
+```shell
+eval $(minikube docker-env)
+``` 
 
 ## Build Docker Base Image
 Speeds up code changes by caching build dependencies.
 ```shell
-docker build -t "hydroflow/gossip-kv-server-base-image:latest" -f examples/server/baseimage.Dockerfile . 
+docker build -t "hydroflow/gossip-kv-server-base-image:latest" -f datastores/gossip_kv/server/baseimage.Dockerfile . 
 ```
 
 ## Build Docker Server Image
 ```shell
-docker build -t "hydroflow/gossip-kv-server:latest" -f examples/server/Dockerfile . 
+docker build -t "hydroflow/gossip-kv-server:latest" -f datastores/gossip_kv/server/Dockerfile .
 ```
 
 ## Check if minikube has the image
 You should see "hydroflow/gossip-kv"
 ```shell
-minikube image ls --format table
-``
+minikube image ls --format tablemin
+```
 
 ## Deploy to Minikube
 ```shell
-kubectl apply -f examples/server/deployment/local
+kubectl apply -f datastores/gossip_kv/server/deployment/local
 ```
