@@ -5,6 +5,8 @@ Tilt is a tool that helps you develop applications for Kubernetes.
 It watches your files for changes, rebuilds your containers, and restarts your pods. 
 It's like having a conversation with your cluster.
 
+This is particularly useful when working on integrations or to test your helm charts.
+Otherwise, you can use your good old docker configuration as described in README.md.

-### SOPS configuration
-
-**Generate a SOPS key**
-
-For this specific step you need to have the `age-keygen` tool installed.
-See https://github.com/FiloSottile/age.
-Then generate a key:
-
-```bash
-age-keygen -o my-age.key
-```
-
-**Install the SOPS key**
-
-Read the SOPS documentation on how to install the key in your environment.
-https://github.com/getsops/sops?tab=readme-ov-file#22encrypting-using-age
-
-On Ubuntu it's like:
-
-```bash
-mkdir -p ~/.config/sops/age/
-cp my-age.key ~/.config/sops/age/keys.txt
-chmod 400 ~/.config/sops/age/keys.txt
-```
-
-**Add the SOPS key to the repository**
-
-Update the [.sops.yaml](../.sops.yaml) file with the **public** key id you generated.

 ### Helmfile in Docker
 
-If you use helmfile in Docker, you may need an additional configuration to make 
-it work with you age key.
-
-You need to mount `-v "${HOME}/.config/sops/age/:/helm/.config/sops/age/"`
-
 ```bash
 #!/bin/sh
 
 docker run --rm --net=host \
    -v "${HOME}/.kube:/root/.kube" \
    -v "${HOME}/.config/helm:/root/.config/helm" \
-   -v "${HOME}/.config/sops/age/:/helm/.config/sops/age/" \
    -v "${HOME}/.minikube:/${HOME}/.minikube" \
    -v "${PWD}:/wd" \
    -e KUBECONFIG=/root/.kube/config \
    --workdir /wd ghcr.io/helmfile/helmfile:v0.150.0 helmfile "$@"

-## Getting started
-
-### Create the kubernetes cluster
+## Create the kubernetes cluster
 
 Run the following command to create a kubernetes cluster using kind:
 
-```bash
-./bin/start-kind.sh
-```
-
-**or** run the equivalent using the makefile
-
 ```bash
 make start-kind
-```
 
-### [Optional] Install the secret
-
-You don't need to do this if you are running the stack with keycloak.
-
-```bash
+# import your secrets from credentials manager
+# ! don't forget "https" before your url
 make install-external-secrets
 ```
 
-### Deploy the application
-
-```bash
-# Pro Connect environment
-tilt up -f ./bin/Tiltfile 
-
-# Standalone environment with keycloak
-DEV_ENV=dev-keycloak tilt up -f ./bin/Tiltfile
-```
-
-**or** run the equivalent using the makefile
-
-```bash
-# Pro Connect environment
-make tilt-up
-
-# Standalone environment with keycloak
-make tilt-up-keycloak
-```
-
 That's it! You should now have a local development environment for Kubernetes.
 
-You can access the application at https://desk.127.0.0.1.nip.io
+## Start the application
+
+```bash
+# You can either start :
+# ProConnect stack (but secrets must be set on your local cluster)
+make tilt-up
+
+# or standalone environment with keycloak
+make start-tilt-keycloak
+```
