Step 6: Preparing for Deployment

Your plugin is built, debugged, and optimized. Now, let's prepare it for release by ensuring compatibility, adding documentation, and following WordPress standards.

Ensuring Compatibility 🛠️

Before releasing your plugin, check for compatibility with:

✅ Latest WordPress version – Always test on the latest stable release.

🔹 Testing Your Plugin

• Use LocalWP, XAMPP, or Docker for a local test environment.
• Test on multiple browsers & devices for frontend compatibility.
• Enable WP_DEBUG to catch hidden errors.

Writing Documentation 📖

A well-documented plugin is easier to use & maintain. Include:

🔹 readme.txt (For WordPress Plugin Directory)

Create a readme.txt file in your plugin folder with:

Translating Your Plugin (Localization) 🌍
