 # docker-wordpress-sqlite
-Fork from official wordpress-php7-apache, with sqlite plugin. For dev purpose or small memory device like Raspberrypi
+Fork from official wordpress4-php7.2-apache, with [sqlite plugin](https://wordpress.org/plugins/sqlite-integration/). For dev purpose or small memory device like Raspberrypi.
+
+### Tags 
+
+- `latest`: amd64
+- `arm32v7`: Raspberry Pi v2 (not tested)
+- `arm64v8`: Raspberry Pi v3 (not tested)
+
+### How to use this image ?
+
+Read [official Readme](https://hub.docker.com/r/_/wordpress/).
+
+Deleted environment variables: `WORDPRESS_DB_*`
+Added environment variables:
+
+- `WORDPRESS_DB_DIR`: location of sqlite file, relative to /var/www/html (default to "database", ie "/var/www/html/database")
+- `WORDPRESS_DB_FILE`: name of sqlite file (default to "database.sqlite")
+
+### MySQL vs SQLite
