+## Repository Overview
 
-If you add new code (Go, Python, Node, Rust, Java, etc.), follow the per-ecosystem quick commands below.
+- **Type**: Shell script project for Linux Mint XFCE post-installation setup
+- **Main scripts**: `post_installation_script/` - Linux Mint XFCE post-installation automation
+- **Testing**: `post_installation_script_test/` - Docker/Podman container-based testing
+- **No build system**: Pure shell scripts, no package.json/Makefile/Cargo.toml
 
-1) Build / Lint / Test commands
+---
 
-- General notes
-  - Run commands from the repository root unless a submodule or service has its own README.
-  - Prefer local, repo-scoped toolchains (venv, node_modules/.bin, go modules, cargo) to avoid global state.
+## 1) Build / Lint / Test Commands
 
-- Shell scripts
-  - Quick check: `shellcheck scripts/*.sh` (install `shellcheck` first).
-  - Run an individual script: `bash path/to/script.sh` or `./script.sh` (ensure executable bit set).
-  - Syntax check: `bash -n path/to/script.sh`
-  - Trace execution: `bash -x path/to/script.sh` (shows each command as it runs)
+### Shell Scripts
 
-- Testing shell scripts
-  - See `post_installation_script_test/README.md` for detailed container-based testing instructions.
-  - Quick start:
-    - Build image: `./post_installation_script_test/01_create_image.sh`
-    - Start container: `./post_installation_script_test/02_start_container_with_image.sh`
+```bash
+# Syntax check only (no execution)
+bash -n path/to/script.sh
 
-- Python (if added)
-  - Install: `python -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt`
-  - Lint: `ruff .` or `flake8 .`
-  - Format: `black .`
-  - Test all: `pytest -q`
-  - Run a single test: `pytest path/to/test_file.py::TestClass::test_method -q`
+# Trace execution (shows each command as it runs)
+bash -x path/to/script.sh
 
-- Node / JavaScript / TypeScript (if added)
-  - Install: `npm ci` or `pnpm install` / `yarn install`
-  - Lint: `npm run lint` (or `npx eslint .`)
-  - Format: `npx prettier --write .`
-  - Test all: `npm test` (or `npx vitest` / `npx jest`)
-  - Run a single test:
-    - Jest: `npx jest path/to/file.test.js -t "test name regex"`
-    - Vitest: `npx vitest run path/to/file.spec.ts -t "test name"`
+# Lint with shellcheck (install with: apt install shellcheck)
+shellcheck post_installation_script/*.sh
 
-- Go (if added)
-  - Build: `go build ./...`
-  - Lint: `golangci-lint run` (if configured)
-  - Test all: `go test ./...`
-  - Run a single test: `go test ./pkg/name -run TestFunctionName`
+# Run individual script
+bash path/to/script.sh
+./script.sh  # requires executable bit: chmod +x script.sh
+```
 
-- Rust (if added)
-  - Build: `cargo build`
-  - Lint: `cargo clippy`
-  - Test all: `cargo test`
-  - Run a single test: `cargo test test_name -- --exact`
+### Container-Based Testing
 
-- Java / Maven (if added)
-  - Build: `mvn -DskipTests package`
-  - Lint/format: use `spotless`/`checkstyle` if configured
-  - Test all: `mvn test`
-  - Run a single test: `mvn -Dtest=ClassName#methodName test`
+```bash
+# Build test image (Ubuntu 22.04 with useful utilities)
+cd post_installation_script_test
+bash 01_create_image.sh
 
-- .NET (if added)
-  - Build: `dotnet build`
-  - Test all: `dotnet test`
-  - Run a single test: `dotnet test --filter FullyQualifiedName~Namespace.ClassName.MethodName`
+# Start interactive container (auto-removed on exit)
+bash 02_start_container_with_image.sh
 
-- CI / Automation
-  - If you add GitHub Actions, keep workflows idempotent and cache dependencies carefully.
-  - Avoid secrets in workflows; read sensitive values from repository/organization secrets.
+# Inside container - source scripts mounted at /workspace:
+bash /workspace/<scriptName>.sh
+```
 
-2) Code style guidelines
+### Single Test Commands (for future languages)
 
-The guidance below is intentionally general and focuses on consistency, readability and safety so
-agentic tools can make changes predictably across multiple languages.
+```bash
+# Python: pytest path/to/test.py::TestClass::test_method -q
+# Node/Jest: npx jest path/to/file.test.js -t "test name regex"
+# Node/Vitest: npx vitest run path/to/file.spec.ts -t "test name"
+# Go: go test ./pkg/name -run TestFunctionName
+# Rust: cargo test test_name -- --exact
+# Java/Maven: mvn -Dtest=ClassName#methodName test
+# .NET: dotnet test --filter FullyQualifiedName~Namespace.ClassName.MethodName
+```
 
-- Formatting
-  - Use an automated formatter for the language (Black for Python, Prettier for JS/TS, gofmt/gofmt -s for Go,
-    rustfmt for Rust). Commit formatted code only.
-  - Use an editorconfig file for basic whitespace/indentation rules when possible.
+---
 
-- Imports / dependencies
-  - Keep imports explicit and minimal: import only what you use.
-  - Group imports in a logical order (language default + third-party + local project). Leave a blank line between groups.
-  - Don’t commit unused dependencies; remove them from lock files / manifests and run the linter.
+## 2) Code Style Guidelines
 
-- Types / typing
-  - Prefer explicit types where the language supports them (TypeScript types, Python type hints, Go static types).
-  - Add types for public interfaces and complex logic; internal simple helper functions may rely on inference.
+### Shell Scripts (Primary Language)
 
-- Naming conventions
-  - Use clear, descriptive names. Prefer `calculate_total`, `prepare_connection`, `user_id` style for snake_case languages.
-  - For camelCase languages (JS/TS): `calculateTotal`, `prepareConnection`.
-  - Types and classes: use PascalCase/UpperCamelCase: `UserService`, `HttpClient`.
-  - Constants: use UPPER_SNAKE_CASE or language-specific constant conventions.
+- **Shebang**: Use `#!/bin/bash` (not `/bin/sh`) for bash-specific features
+- **Safety**: Use `set -euo pipefail` at script start
+- **Quotes**: Always use double quotes for variable expansion: `"$VAR"`, never bare `$VAR`
+- **Conditionals**: Use `[[ ]]` for tests, not `[ ]`
+- **Variables**: Use `readonly` for constants, `local` for function-scoped variables
+- **Performance**: Prefer functions over subshells when possible
+- **Naming**: Use descriptive function names: `install_fonts()`, `configure_panel()`, `prompt_user()`
+- **Errors**: Write to stderr: `echo "Error: $msg" >&2`
+- **Exit codes**: 0=success, 1=general error, 2=invalid usage
+- **Comments**: Avoid unless explaining non-obvious behavior
+- **Constants**: Define at top of script, UPPER_SNAKE_CASE
 
-- Functions and modules
-  - Keep functions small (ideally < 40 lines) and single-responsibility.
-  - Prefer pure functions where possible; keep side effects explicit and isolated.
-  - Organize modules by feature/domain, not solely by type (avoid monolithic god-modules).
+### General Conventions
 
-- Error handling
-  - Fail fast and return/raise errors with context (message + cause) rather than swallowing them.
-  - Avoid logging raw errors in library code; return errors to callers and let the application layer decide logging.
-  - Use typed error types when the language supports it (Go error types, custom exceptions in Python/JS).
-  - Clean up resources with `finally`/`defer` equivalents to avoid leaks.
+- **Formatting**: Use automated formatters (Black/Prettier/gofmt/rustfmt) - commit formatted code
+- **Types**: Prefer explicit typing (TypeScript types, Python type hints, Go static types)
+- **Naming**:
+  - snake_case: variables, functions (`user_id`, `calculate_total`)
+  - PascalCase: types/classes (`UserService`, `HttpClient`)
+  - UPPER_SNAKE_CASE: constants (`MAX_RETRIES`, `API_BASE_URL`)
+- **Imports**: Keep minimal, group logically (stdlib → third-party → local), blank line between groups
+- **Functions**: Keep small (<40 lines), single responsibility, pure where possible
+- **Error handling**: Fail fast with context, avoid silent failures, use typed errors where supported
+- **Tests**: Deterministic, mock external I/O, explicit names like `test_should_return_400_when_missing_field`
+- **Resources**: Always clean up with `finally`/`defer` equivalents
 
-- Tests
-  - Prefer small, deterministic unit tests. Mock external IO and network where reasonable.
-  - Use explicit fixtures and avoid implicit global state between tests.
-  - Name tests with the behavior they assert: `test_calculate_total_with_discounts` or `shouldReturn400WhenMissingField`.
+---
 
-- Logging and observability
-  - Use structured logging where available (JSON structured logs for services).
-  - Avoid printing raw stack traces to stdout in production code; include them at debug level.
+## 3) Security
 
-- Security and secrets
-  - Never commit secrets, API keys, or credentials. Use environment variables and vaults.
-  - Validate and sanitize external input at the boundaries of the system.
+- Never commit secrets, API keys, credentials, or tokens
+- Use environment variables for sensitive values
+- Validate and sanitize all external input
+- Run linting (`shellcheck`) before committing shell scripts
 
-- Performance
-  - Measure before optimizing. Prefer clarity over micro-optimizations unless a hotspot is identified.
+---
 
-3) Code review / commit guidance for agents
+## 4) Commit Guidelines
 
-- Make small, focused commits and include a one-line summary plus a short description of the why.
-- When changing behavior, add or update tests that verify the new/changed behavior.
-- If you reformat files automatically, include the formatter command in the commit message to make CI reproduction easy.
+- Make small, focused commits with descriptive messages
+- Include formatter command in commit message if auto-formatting
+- When changing behavior, add or update tests
+- Run full test suite before opening PRs
 
-4) Repo housekeeping checks (recommended for agents)
+---
 
-- When adding a new language or framework, add an entry to this file with the exact commands required to build/test.
-- Add CI workflows to run lint + tests on PRs and enable branch protection rules if this becomes a shared repo.
-- **Session storage**: Store session logs and working notes in `.agents/sessions/` folder for future reference. Use descriptive filenames (e.g., `session-<date>-<topic>.md`).
+## 5) Cursor / Copilot Rules
 
-5) Cursor / Copilot rules
+- `.cursor/rules/`: Not present
+- `.cursorrules`: Not present
+- `.github/copilot-instructions.md`: Not present
 
-- Cursor rules: none present at `.cursor/rules/` or `.cursorrules` in this repository.
-- GitHub Copilot instructions: none present at `.github/copilot-instructions.md`.
+---
 
-If you add any of these files, update this document and include the exact file path and relevant sections for agents to follow.
+## 6) Repo Housekeeping
 
-Quick checklist for an agent making changes
-- Run local linter/formatter configured for the language before opening a PR.
-- Run the test suite and the single-test command for any tests you added/changed.
-- Do not add secrets to the tree; use placeholders and document required environment variables.
+- Store session logs in `.agents/sessions/` for reference
+- When adding new languages, update this file with exact build/test commands
 
-Next steps (recommended)
-1) Add a minimal `Makefile` or `package.json` scripts for common tasks so agents can run `make test` / `npm test`.
-2) If the project will contain multiple services, add per-service README files and CI workflows.
-3) Add EditorConfig + language-specific formatter configs (pyproject.toml, .prettierrc, rustfmt.toml) to lock formatting rules.

 ## Release Process
 
-This project uses a simple release process based on git tags.
+This project uses a two-step release process.
 
 ### Versioning
 - Version is stored in `VERSION` file (format: v0, v1, v2, ...)
-- Major version increments only (major-bugfix scheme)
-- Script version is also stored in `SCRIPT_VERSION` variable within the main script to display version during script execution
+- Major version increments only
+- Script version stored in `SCRIPT_VERSION` variable
 
-### Creating a Release
-Run the release script from the repository root:
+### Step 1: Prepare Release
+- Make sure you are on main branch with no local changes. Script will abort otherwise
+Run from repository root:
 ```bash
-./release.sh
+./01_prepare_release.sh
 ```
 
 The script will:
-1. Check for uncommitted local changes (exits if any exist)
-2. Show current version and propose next version
-3. Prompt for confirmation
-4. Update VERSION file and SCRIPT_VERSION in the script
-5. Create a git commit
-6. Create an annotated tag
-7. Prompt to push to origin (including tags)
+- Update VERSION file and SCRIPT_VERSION in the script
+- Create a release branch (e.g., `release/v1`)
+- Push the release branch
 
-### Gitea Integration
-When a tag is pushed to the remote, Gitea automatically creates a release from it.
+### After step 1 (manual)
+- Create and merge PR from release branch to main
+
+### Step 2: Finalize Release (After PR Merged)
+Run from repository root:
+```bash
+./02_finalise_release.sh
+```
+
+The script will:
+- Create and push tag for release version to main
+
+### After step 2 (manual)
+- Create a release in gitea
 
 ### Requirements
 - Clean working tree (no uncommitted changes)

-## - Microsoft Aptos Fonts.zip
-## - google-fonts.tar.gz

-# xfce4-goodies (zusätzliche Elemente für die Taskleiste)
-# xfce4-panel-profiles (Tool für die Taskleistenbearbeitung)
-# clementine  (Audioplayer und Musikbibliothekverwaltung)
-# vlc (weltbester Mediaplayer ;-))
-# htop (Systemmonitortool)
-# hardinfo (Übersicht der Systemeigenschaften)
-# font-manager (Schriftarten verwalten)
-# asunder (Audio-CDs in z.B. mp3-Dateien verwandeln (rippen))
-# gtkhash (Prüfsummen von Dateien erstellen und überprüfen)
