-# Database Testing Suite
-
-This docker setup is designed to run BookStack's test suite against each major database version we support
-across MySQL and MariaDB to ensure compatibility and highlight any potential issues before a release.
-This is a fairly slow and heavy process, so is designed to just be run manually before a release which
-makes changes to the database schema, or a release which makes significant changes to database queries.
-
-### Running
-
-Everything is ran via the `run.sh` script. This will:
-
-- Optionally, accept a branch of BookStack to use for testing.
-- Build the docker image from the `Dockerfile`.
-  - This will include a built-in copy of the chosen BookStack branch. 
-- Cycle through each major supported database version:
-  - Migrate and seed the database.
-  - Run the full PHP test suite.
-
-If there's a failure for a database version, the script will prompt if you'd like to continue or stop testing.
-
-This script should be ran from this `db-testing` directory:
-
-```bash
-# Enter this directory
-cd dev/docker/db-testing
-
-# Runs for the 'development' branch by default
-./run.sh
-
-# Run for a specific branch
-./run.sh v25-11
