+# 1. CISS.debian.installer
+
+**Centurion Intelligence Consulting Agency Information Security Standard**<br>
+*The CISS Debian Installer provides a fully automated and hardened installation process.*<br>
+**Master Version**: 8.00<br>
+**Build**: V8.00.000.2025.06.17<br>
+
+# 2. Preliminary Components – `cdi_0000_preliminary`
+
+This directory contains foundational wrapper scripts for the `CISS.debian.installer` framework. These scripts serve as minimal
+but essential building blocks to ensure consistent versioning, usage helps output, and contact information across the entire 
+installer suite.
+
+## 2.1. Purpose and Functionality
+
+The scripts in this module fulfill the following roles:
+
+- **0001_contact.sh**:  
+  Displays project-related contact details, including PGP fingerprint, security email, and project links. This is shown during
+  installer execution or upon request via CLI.
+
+- **0002_usage.sh**:  
+  Provides a user-facing, color-coded help dialog. It details available command-line options such as debugging modes 
+  (`--debug`), logging configuration, and non-interactive autoinstallation. It also enforces preconditions such as root 
+  privileges, and the presence of YAML configuration files.
+
+- **0003_version.sh**:  
+  Displays the current project version, latest Git commit, debootstrap version, and host Bash version. This helps contextualize 
+  the environment for debugging and auditing.
+
+## 2.2. Requirements
+
+- Bash version ≥ 5.1
+- Proper invocation context (`set -Ceuo pipefail` enforced)
+- Pre-populated configuration files:
+  - `.preseed/preseed.yaml`
+  - `.preseed/partitioning.yaml`
+  - Password files for GRUB, LUKS boot, common, and nuke passphrases
+
+These scripts assume they are sourced or executed within a controlled setup shell, with essential global variables 
+(e.g. `VAR_VERSION`) predeclared.
+
+
+## 2.3. Dependencies
+
+- `bash` built-ins only (no external binaries invoked except `git`, `debootstrap`, and `uname` in `0003_version.sh`)
+- ANSI color-supporting terminal (via `tput cols`, `echo -e`)
+- Git repository context for versioning (`git log`)
