 Here are more explanation:
- 1. **Get stack if exist**: Victor create a new Pulumi workspace in your Drone pipeline, then create a stack, and if the webserver contains a state file, loads it. This enable the following to work properly.
+ 1. **Get stack if exist**: Victor create a new Pulumi workspace in your GitHub Action workflow or Drone pipeline, then create a stack, and if the webserver contains a state file, loads it. This enable the following to work properly.
  2. **Update**: by comparing the existing and actualised resources (does a refresh first) to the target, Victor enable fine-grained continuous deployment of your resources.
  3. **Push updated stack**: finally, Victor exports the stack state file and uploads it in the webserver such that future iterations will be able to load it, to really do **continuous** deployment.
