-## Usage
+## Package Building
+
+### Quick Package Building
+
+```bash
+# Build distribution packages (recommended)
+make package
+
+# This will:
+# 1. Show current version (setuptools-scm)
+# 2. Clean previous builds
+# 3. Build both wheel and source distribution
+# 4. Show package details
+```
+
+### Manual Building
+
+```bash
+# Standard build
+make build
+
+# Using release script
+make release-build
+python release.py build
+
+# Manual Python build
+python -m build
+```
+
+## Publishing Workflow
+
+### Complete Release + Publishing
+
+```bash
+# 🚀 ONE-COMMAND RELEASE (recommended)
+make release-publish-gitea VERSION=0.8.0
+
+# This complete workflow:
+# 1. Creates git tag v0.8.0
+# 2. Builds packages (setuptools-scm uses tag for version 0.8.0)
+# 3. Uploads both wheel and source distribution to Gitea
+```
+
+### Step-by-Step Release
+
+```bash
+# 1. Check current status
+make release-status
+
+# 2. Validate release readiness
+make release-validate
+
+# 3. Create git tag
+make release-tag VERSION=0.8.0
+
+# 4. Build packages (version auto-detected from tag)
+make release-build
+
+# 5. Upload to Gitea registry
+make release-upload-gitea
+```
+
+### Development Package Testing
+
+```bash
+# Build current development version
+make package
+
+# Upload development packages for testing
+python release.py upload --dry-run  # Test first
+python release.py upload            # Upload development version
+```
+
+## Registry Management
 
 ### Check Registry Status
 
 ```bash
-# Check registry configuration and authentication
+# Comprehensive registry information
 make release-registry
-# or
-python release.py registry
+
+# Shows:
+# - Authentication status
+# - Registry URLs
+# - Existing packages
+# - Configuration details
 ```
 
-### Build and Upload Packages
+### Upload Existing Packages
 
 ```bash
-# Complete release workflow with Gitea upload
-make release-publish-gitea VERSION=0.8.0
-# or
-python release.py publish --version 0.8.0 --to-gitea
-
-# Upload existing packages
+# Upload packages in dist/ folder
 make release-upload-gitea
-# or
-python release.py upload
 
-# Dry run (test without uploading)
+# With dry-run testing
 python release.py upload --dry-run
+python release.py upload
 ```
 
-### Traditional Release (without Gitea)
+### Traditional Release (Git tags only)
 
 ```bash
 # Standard release without Gitea upload
 make release-publish VERSION=0.8.0
-python release.py publish --version 0.8.0
 ```
