 ## Roadmap
 In the near future the following will happen:
 
-1. [Kubeflow][]
-   - [x] Support `>=v1.4.1`
-   - [x] Support `>=v1.5.0` (April 2022)
-2. Features
-   - [x] Change standard user/password as input variable (February 2022)
-   - [ ] Installation on a Jetson Nano including GPU Support (May 2022)
+- [ ] Splitting the state into smaller parts, perhaps by using multiple 
+  modules. We think the state should be placed inside the cluster, but 
+  currently it is too big to do so. (June 2022)
+- [ ] Replace 'kubernetes' provider with 'kubectl' provider. Both provider 
+  do basically the same thing. (July 2022)
+- [ ] Installation on a Jetson Nano (ARMv8-64) including GPU support. (~~May~~ 
+  August 2022)
