+### Release Package Creation - Critical Notes
+
+**IMPORTANT:** The zip command must be run from the **parent directory** to create proper archive structure.
+
+**Correct command (from `/home/magdev/workspaces/php`):**
+
+```bash
+cd /home/magdev/workspaces/php
+zip -r wc-tier-and-package-prices/releases/wc-tier-and-package-prices-X.X.X.zip wc-tier-and-package-prices/ \
+  -x '*/\.git/*' '*/.git/*' 'wc-tier-and-package-prices/.git/*' \
+  '*.gitignore' '*.log' '*/.claude/*' '*/CLAUDE.md' \
+  '*/releases/*' '*/wordpress/*' '*/node_modules/*' \
+  '*/.DS_Store' '*/Thumbs.db' '*/.vscode/*' '*/.idea/*' \
+  '*.sublime-*' '*/notes.*' '*/logs/*' '*/templates/cache/*' \
+  '*/composer.lock'
+```
+
+**Critical Exclusions:**
+
+- `*/wordpress/*` - MUST be excluded! The project has a symlink to WordPress installation that zip will follow, creating 129MB+ packages instead of ~430KB
+- `.git/*` - All git metadata (multiple patterns needed for reliability)
+- `.claude/*` and `CLAUDE.md` - Development documentation
+- `releases/*` - Prevents including previous releases in new ones
+- `composer.lock` - Not needed in production (vendor/ is included)
+
+**Expected Package Size:** ~430-431KB (383 files)
+
+**Package Size Alert:** If >1MB, exclusions failed (likely wordpress symlink included)
+
+**Verification Steps:**
+
+```bash
+# 1. Check size (should be ~430KB)
+ls -lh releases/wc-tier-and-package-prices-X.X.X.zip
+
+# 2. Verify file count (should be 383 files)
+unzip -l releases/wc-tier-and-package-prices-X.X.X.zip | tail -1
+
+# 3. Check for excluded files
+unzip -l releases/wc-tier-and-package-prices-X.X.X.zip | grep -E "CLAUDE\.md|\.claude/|\.git/|wordpress/"
+# Should return nothing (exit code 1)
+
+# 4. Verify version in package
+unzip -p releases/wc-tier-and-package-prices-X.X.X.zip wc-tier-and-package-prices/wc-tier-and-package-prices.php | head -30 | grep -E "Version:|WC_TPP_VERSION"
