 - **Memory:** 4 GB
 - **CPU:** 1 processor, 2 cores
-- **Hard Disk:** SCSI, 60 GB
+- **Hard Disk:** SCSI, 300 MB
+- **CD/DVD**: IDE
+- **Network Adapter**: Bridged
 
-In case you're setting up a VMWare virtual machine, select OS type *Other Linux 3.x kernel 64-bit* and after you create the VM, manually edit the `*.vmx` file using a text editor and set there `mem.hotadd = "FALSE"`. Failing to do so will result in system unable to boot. Other hypervizors don't need this adjustment.

+## Virtual Machine creation
 
 Download **Alpine Virtual 3.8.0 x86_64** from <https://alpinelinux.org/downloads/> and boot from it. At the login prompt, use the root user without password to log in.

-The script will perform the bare Alpine linux installation into VM using LUKS-on-LVM. The default disk encryption password is `password`. No root password is set.
+The script will perform installation and configuration of Alpine linux, LXC and the whole VMMgr platform. Virtual machine is protected by LUKS-on-LVM disk encryption. The encryption password, which is simultaneously also a password for VMMgr web administration interface, will be asked for at the beginning of the script execution. Root access is disabled.
 
-## Application installation
+After the script finishes and shuts down the virtual machine, remove CD/DVD drive from the virtual machine settings and extend the HDD to 80 GB. This is to minimize the overall size of the OVA (Open Virtual Appliance) file to which the VM will be exported.
+
+## Application Build environment creation
 
 ### First time setup
+
+Follow the VM creation steps as above, but comment the line disabling the root login in *alpine.sh* file before its execution. After the script finishes and HDD size is adjusted, add serial port in the virtual machine settings and set it to use Unix socket or named pipe (eg. `\\.\pipe\alpine`). Ten start the VM and connect to the serial port using *screen*, *PuTTY* or any other terminal client.

 # Clone the repository

+git clone --recurse-submodules ssh://git@gitlab.dasm.cz:2222/Spotter-Cluster/Spotter-Cluster.git
 
-# Enter the repository directory
-cd Spotter-Cluster
-
-# Optional: Edit the install sequence script
-vi 00-install.sh
-
-# Launch the script
-./00-install.sh
+# Install the build toolchain
+Spotter-Cluster/zz-build/install-toolchain.sh
 ```
 
-### Resuming from a snapshot
-Assumes that the repository has already been cloned.
+After the script finishes, it is possible to connect via SSH as the toolchain sets up also *openssh-server*.
+
+### Building the packages
+There are 3 distinct packaging systems.
+
+1. Just a plain tar for basic OS setup used by *alpine.sh* installation script.
+2. Abuild for the native Alpine linux packages (APK) used for LXC, ACME client and VMMgr packaging.
+3. `lxc-build`/`lxc-pack` for LXC images building and packaging.
+
+Full build of all components is automated via *build-all.sh* script. Before the script can be run, signing keys need to be put in place
 ```
-# Enter the repository directory
-cd Spotter-Cluster
+# Supply Abuild signing key
+vi /srv/build/repokey.rsa
 
-# Update repository
-git pull
+# Supply lxc-pack signing key
+vi /srv/build/packages.key
 
-# Optional: Edit the install sequence script
-vi 00-install.sh
-
-# Launch the script
-./00-install.sh
+# Build all packages
+Spotter-Cluster/zz-build/build-all.sh
 ```
 
+The full build process takes considerable amount of time, so it is advised to have a persistent build VM.
