-# Version Update Scripts
-
-This directory contains scripts to update the version across the Elytra PIM Client project before building a wheel distribution.
-
-## Quick Start
-
-Update version and build:
-```bash
-# Python (cross-platform)
-python update_version.py 1.0.0
-python build_wheel.py
-
-# PowerShell (Windows)
-.\update_version.ps1 1.0.0
-.\build_wheel.ps1
-
-# Bash (Linux/macOS)
-./update_version.sh 1.0.0
-./build_wheel.sh
-```
-
-## Files Updated
-
-The version update scripts modify the following files:
-- `pyproject.toml` - Project configuration (line 7)
-- `elytra_client/__init__.py` - Package version (line 3)
-
-## Available Scripts
-
-### Python Version
-```bash
-python update_version.py 0.2.0
-```
-
-**Usage:**
-```bash
-python update_version.py <version>
-```
-
-**Example:**
-```bash
-python update_version.py 1.0.0
-```
-
-### PowerShell Version
-```powershell
-.\update_version.ps1 -Version 0.2.0
-```
-
-**Usage:**
-```powershell
-.\update_version.ps1 -Version <version>
-# or
-.\update_version.ps1 <version>
-```
-
-**Examples:**
-```powershell
-.\update_version.ps1 0.2.0
-.\update_version.ps1 -Version 1.0.0
-```
-
-### Bash Version
-```bash
-./update_version.sh 0.2.0
-```
-
-**Usage:**
-```bash
-./update_version.sh <version>
-```
-
-**Example:**
-```bash
-./update_version.sh 1.0.0
-```
-
-## Version Format
-
-The version must follow semantic versioning format: `major.minor.patch`
-
-Valid examples:
-- `0.1.0`
-- `1.0.0`
-- `0.2.1`
-- `1.0.0-beta` (with pre-release identifier)
-
-Invalid examples:
-- `1.0` (missing patch version)
-- `v1.0.0` (invalid prefix)
-
-## Workflow
-
-### Before Building a Wheel
-
-1. **Update the version:**
-   ```bash
-   # On Windows
-   .\update_version.ps1 0.2.0
-
-   # On Linux/macOS
-   ./update_version.sh 0.2.0
-   ```
-
-2. **Build the wheel:**
-   ```bash
-   # Using Python
-   python build_wheel.py
-
-   # Or PowerShell
-   .\build_wheel.ps1
-
-   # Or Bash
-   ./build_wheel.sh
-   ```
-
-3. **Upload (optional):**
-   ```bash
-   .\upload_wheel_to_forgejo_pypi.ps1
-   ```
-
-### Verification
-
-After running the update script, verify the changes:
-
-**Check pyproject.toml:**
-```bash
-grep "version = " pyproject.toml
-```
-
-**Check __init__.py:**
-```bash
-grep "__version__ = " elytra_client/__init__.py
-```
-
-## Error Messages
-
-### Invalid Version Format
-```
-✗ Invalid version format: 1.0
-Version must follow semantic versioning (major.minor.patch)
-Examples: 1.0.0, 0.2.0, 1.0.0-beta
-```
-
-**Solution:** Use the format `major.minor.patch` (e.g., `1.0.0`)
-
-### File Not Found
-```
-✗ /path/to/file not found
-```
-
-**Solution:** Ensure you're running the script from the project root directory
-
-## Return Codes
-
-- `0` - Success (version updated)
-- `1` - Error (see error message)
-
-## Notes
-
-- Run from the project root directory
-- The scripts will show which files were updated
-- All scripts support semantic versioning with optional pre-release identifiers
-- Use consistent versions across all files to avoid build issues
