 Refer to the `README.md` file in there and follow the instructions. Note that it is usually required one time. If Rapid Space's keys are already enrolled on the machine and they are the one in `uefi-keys/keys`, then you can proceed to [the next step](#initramfs-image) of the current document.
 
-## Initramfs image
+## Create an initramfs image
 This stage is about creating and signing an initramfs image with the Metadata Collect Agent (MCA) enabled in it.
 
 ### Install dependencies
-Run `sudo ./installation/dependencies.sh`
+Run `./generation/10install-dependencies.sh`
 
-### Install the dracut module and signed initramfs image
-Run `sudo ./installation/install.sh`
+### Get the target kernel
+To choose the right kernel version, set the variable `KERNEL_VERSION` in `./generation/00env.sh`.
 
-Notes:
+Run `./generation/20get-kernel-package.sh`
+
+### Generate the image
+The configuration file can be modified here: `./dracut.module/dracut.conf.in`
+
+Run `30generate-image.sh`
+
+### Upload the image
+Run `40upload-image.sh` to upload the image in shacache and create an entry in shadir.
+
+
+## Install an initramfs image
+This stage is about installing an image on the machine.
+
+### Install dependencies
+Run `./installation/10install-dependencies.sh`
+
+### Generate the network script
+This step has to be performed only once unless the network configuration has been changed.
+
+Run `./installation/20generate-get-network.sh`
+
+### Install the image
+Run `30install-image.sh`
+
+### Notes
 * The installation of the dracut module is performed by `dracut.module/Makefile`. 
 * The initramfs image is created by dracut according to the preferences in dracut.module/dracut.conf and the command-line.
 * The (unsigned) initramfs image is then signed by dracut, again according to dracut.module/dracut.conf
