+# docker-osx
+
+## Information
+
+This installs `docker-osx` in Kubernetes.
+
+## Requirements
+
+*) Kubernetes
+*) Helm
+*) `sickcodes/docker-osx-vnc` Docker image
+
+### Build `sickcodes/docker-osx-vnc`
+
+1) Go back to the root directory
+1) Build docker image
+
+    ```
+    docker build \
+        -t sickcodes/docker-osx-vnc:latest \
+        -f vnc-version/Dockerfile .
+    ```
+
+_Do not worry about passing `CPU`, `RAM`, etc as they are handled in `values.yaml` now._
