 ## Usage
 
 Step 1 - Clone the git repository.
 
-Step 2 - Edit the respective JSON files, e.g. `ubuntu/ubuntu-22.04.json` file or `photon/photon-3.0.json`. For Ubuntu 20.04 and 22.04, adapt the `user-data` cloud-init file with the desired configuration ([documentation](https://ubuntu.com/server/docs/install/autoinstall-reference) for reference).
+Step 2 - Make a copy (or change) and adapt the [cloud definition file](https://github.com/cloudmaniac/packer-templates/tree/main/builds/clouds) to your environment (you will find them in the `builds/clouds` folder).
+
+Step 3 - Update the `buils/common.pkrvars.hcl` file with your desired user credentials (or SSH key).
+
+Step 4 - Navigate to the folder that matches the operating system (and version) that you want to build. E.g.: `builds/ubuntu/22.04`.
+
+Step 4 - From that folder, edit the respective HCL file with your values, e.g. `ubuntu-22.04.auto.pkrvars.hcl` file or `photon-4.0.auto.pkrvars.hcl`. For Ubuntu 20.04 and 22.04, adapt the `user-data` cloud-init file with the desired configuration ([documentation](https://ubuntu.com/server/docs/install/autoinstall-reference) for reference).
 
-Step 3 - Adapt one of the [cloud definition JSON file](https://github.com/cloudmaniac/packer-templates/tree/master/clouds) to your environment (you will find them in the `clouds` folder).
+Step 5 - Run `packer init .` to install the required plugin(s).
 
-Step 4 - Build the template(s).
+Step 6 - Build your template with `packer build -force -var-file="../../clouds/infra-z67.pkrvars.hcl" -var-file="../../common.pkrvars.hcl" .`.
+*Note: adapt to filenames and location relevant to your environment.*
 
-* Either manually by using the `packer` CLI: `packer build -var-file=../clouds/var-infra-z67.json ubuntu-20.04.json`
-* Or by using a quick script, e.g.: `./ubuntu/build-ubuntu-20.04.sh`
+Step 7 - Rinse and repeat for all templates you want to build. \o/
 
 ## Todo
 
-* Migrate from JSON to HCL2
 * Add support for additional OS (Debian, CentOS, Windows)
 * Zero the disk before export
 * Use the Content Library to store the ISOs
