 ## Development (w/ Kuberentes)
 
-Install [Nix](https://github.com/LCOGT/public-wiki/wiki/Install-Nix) and then
-enter the development environment:
+Always enter the development shell before doing anything else. This will make
+sure everyone is using the same version of tools, to avoid any system discrepancies.
 
-```shell
-nix develop --impure
+Install [Nix](https://github.com/LCOGT/public-wiki/wiki/Install-Nix) if you have
+not already.
+
+If you have [direnv](https://github.com/LCOGT/public-wiki/wiki/Install-direnv)
+installed, the shell will automatically activate and deactive anytime you change
+directories. You may have to grant permissions initially with:
+
+```sh
+direnv allow
 ```
 
-Start a local development K8s cluster and container registry:
+Otherwise, you can manually enter the shell with:
 
-```shell
-ctlptl apply -f ./local-registry.yaml -f ./local-cluster.yaml
+```sh
+./develop.sh
 ```
 
 Spin up dependencies:
 
-```shell
+```sh
 skaffold -m mop-deps run
 ```
 
 Start development loop:
 
-```shell
+```sh
 skaffold -m mop dev
 ```
 
 This will watch source-code files for any changes and re-deploy automatically
 when they are modified.
 
-The application will be port-forwarded to a port listed in the logs:
+If you don't want that behaviour, you can also just have it run in the background:
 
+```sh
+skaffold -m mop run
 ```
-...
-Deployments stabilized in 13.077 seconds
-Port forwarding Service/server in namespace mop, remote port http -> http://127.0.0.1:4503
-Listing files to watch...
- - mop
-Press Ctrl+C to exit
-...
-```
+
+MOP should be running at https://mop.local.lco.earth
 
 ### Clean-up
 
-You can simply delete the application specific development cluster to clean everything up:
+You can delete all resources deployed by skaffold with:
 
-```shell
-ctlptl delete -f ./local-cluster.yaml
+```sh
+skaffold -m mop,mop-deps delete
 ```
