+# Migrating from Lando to DDEV
+
+This document explains how to migrate from Lando to DDEV for local development.
+
+## Prerequisites
+
+1. Install DDEV: https://ddev.readthedocs.io/en/stable/#installation
+2. Stop and remove your Lando environment (optional, but recommended to free resources):
+   ```
+   lando stop
+   lando destroy
+   ```
+
+## Migration Steps
+
+### 1. Start DDEV
+
+```bash
+ddev start
+```
+
+This will:
+- Download required Docker images
+- Create containers for web server, database, and other services
+- Run the `scripts/create-settings.sh` hook to create local settings file
+
+### 2. Install Drupal
+
+If you're setting up from scratch:
+
+```bash
+ddev drush si minimal --existing-config
+```
+
+### 3. Import Content (Optional)
+
+If you want default content for development:
+
+```bash
+ddev drush dcdi --force update
+ddev drush cr
+```
+
+### 4. Get Login Link
+
+```bash
+ddev drush uli
+```
+
+### 5. Access Your Site
+
+Your site will be available at:
+- http://drupalcz.ddev.site
+- https://drupalcz.ddev.site (if mkcert is installed)
+
+## Useful DDEV Commands
+
+| Lando Command | DDEV Equivalent |
+|---------------|-----------------|
+| `lando start` | `ddev start` |
+| `lando stop` | `ddev stop` |
+| `lando poweroff` | `ddev poweroff` |
+| `lando drush <command>` | `ddev drush <command>` |
+| `lando composer <command>` | `ddev composer <command>` |
+| `lando ssh` | `ddev ssh` |
+| `lando db-import <file>` | `ddev import-db --src=<file>` |
+| `lando db-export` | `ddev export-db` |
+| `lando logs` | `ddev logs` |
+
+## Database Migration
+
+If you have an existing database in Lando that you want to migrate:
+
+1. Export from Lando:
+   ```bash
+   lando db-export database.sql.gz
+   ```
+
+2. Stop Lando and start DDEV:
+   ```bash
+   lando stop
+   ddev start
+   ```
+
+3. Import into DDEV:
+   ```bash
+   ddev import-db --src=database.sql.gz
+   ddev drush cr
+   ```
+
+## Files Migration
+
+If you have user-uploaded files:
+
+1. Your files in `docroot/sites/default/files/` will remain in place
+2. Private files are now expected at `/var/www/html/private` inside the container
+
+## Frontend Development
+
+The original Lando setup included Node.js for theme development. For DDEV, you have two options:
+
+### Option 1: Use DDEV's Node service (Recommended)
+
+Add to `.ddev/config.yaml`:
+```yaml
+web_extra_daemons:
+  - name: "node"
+    command: "/var/www/html/docroot/themes/custom/dcz_theme && npm install && npm run watch"
+    directory: /var/www/html/docroot/themes/custom/dcz_theme
+```
+
+### Option 2: Use Node.js on your host machine
+
+Install Node.js locally and run:
+```bash
+cd docroot/themes/custom/dcz_theme
+npm install
+npm run watch
+```
+
+## Differences from Lando
+
+- **Database host**: Changed from `database` to `db`
+- **Database credentials**: All are `db` (name, username, password)
+- **Project URL**: Changed from `*.lndo.site` to `*.ddev.site`
+- **Mailhog**: Available at http://drupalcz.ddev.site:8025
+- **PHP version**: 7.4 (same as Lando)
+- **Web server**: Apache (same as Lando)
+
+## Custom Settings Structure
+
+This project uses a custom settings file structure instead of DDEV's default `settings.ddev.php`:
+
+1. **Main settings**: `docroot/sites/default/settings.php` includes `docroot/sites/default/settings/includes.settings.php`
+2. **DDEV detection**: `includes.settings.php` detects DDEV via the `IS_DDEV_PROJECT` environment variable
+3. **DDEV settings**: When DDEV is detected, it loads `docroot/sites/default/settings/ddev.settings.php`
+4. **Local overrides**: Finally, it loads `docroot/sites/default/settings/local.settings.php` if it exists
+
+This structure allows the same codebase to work with Lando, DDEV, Acquia Cloud, and other environments without modification.
+
+## Troubleshooting
+
+### Clear cache if you have issues
+```bash
+ddev drush cr
+```
+
+### Restart DDEV
+```bash
+ddev restart
+```
+
+### Check DDEV status
+```bash
+ddev describe
+```
+
+### View logs
+```bash
+ddev logs
+```
+

+# DDEV Migration Summary
+
+## Files Created
+
+1. **`.ddev/config.yaml`** - Main DDEV configuration file
+   - Configures Drupal 9, PHP 7.4, Apache, MariaDB 10.4
+   - Disables DDEV's automatic settings management (we use custom structure)
+   - Includes post-start hook to create local settings file
+
+2. **`docroot/sites/default/settings/ddev.settings.php`** - DDEV-specific settings
+   - Database connection configuration (db/db/db on host 'db')
+   - Development-friendly settings (caching disabled, update access enabled)
+   - Config split configuration for development
+   - Private files path and other Drupal settings
+
+3. **`DDEV_MIGRATION.md`** - Migration guide
+   - Step-by-step instructions for migrating from Lando to DDEV
+   - Command reference table
+   - Database and files migration instructions
+   - Troubleshooting tips
+
+## Files Modified
+
+1. **`docroot/sites/default/settings/includes.settings.php`**
+   - Added DDEV environment detection using `IS_DDEV_PROJECT` environment variable
+   - Loads `settings/ddev.settings.php` when running in DDEV
+
+2. **`.gitignore`**
+   - Added DDEV-specific ignore patterns
+
+3. **`README.md`**
+   - Added DDEV setup instructions
+   - Added reference to migration guide
+
+## How It Works
+
+### Settings Loading Chain:
+1. Drupal loads `docroot/sites/default/settings.php`
+2. Which includes `docroot/sites/default/settings/includes.settings.php`
+3. `includes.settings.php` checks for environment:
+   - If `IS_DDEV_PROJECT=true` → loads `settings/ddev.settings.php`
+   - If `LANDO_APP_NAME` exists → loads `settings/lando.settings.php`
+   - If `AH_SITE_ENVIRONMENT` exists → loads Acquia Cloud settings
+4. Finally loads `settings/local.settings.php` for any local overrides
+
+### Database Configuration:
+- **Host**: `db` (DDEV's database container)
+- **Database**: `db`
+- **Username**: `db`
+- **Password**: `db`
+- **Port**: `3306`
+
+This setup ensures that:
+- Both Lando and DDEV can work simultaneously (different environment detection)
+- No code changes needed when switching between environments
+- Settings are organized and maintainable
+- DDEV doesn't interfere with the custom settings structure
+
+## Quick Start
+
+```bash
+# Start DDEV
+ddev start
+
+# Check status
+ddev drush status
+
+# Get login link
+ddev drush uli
+
+# Access site at:
+# http://drupalcz.ddev.site
+```
+
+## Note on settings.ddev.php
+
+DDEV normally auto-generates a `settings.ddev.php` file in `docroot/sites/default/`.
+This project uses a custom settings structure, so we:
+- Set `disable_settings_management: true` in `.ddev/config.yaml`
+- Use `docroot/sites/default/settings/ddev.settings.php` instead
+- This allows better organization and multi-environment support
