+# Contributing to Fluent's MySQL Driver
+
+👋 Welcome to the Vapor team! 
+
+## Database
+
+In order to build and test against Postgres, you will need a database running. The easiest way to do this is using Docker and the included `docker-compose.yml` file.
+
+If you have Docker installed on your computer, all you will need to do is:
+
+```fish
+docker-compose  mysql-a mysql-b
+# or for mariadb
+docker-compose  mariadb-a mariadb-b
+```
+
+This will start the two databases required for running this package's unit tests. One of the databases will run on MySQL's default port 3306 and the other on 3307.
+
+### Environment Variables
+
+You will need to set the following environment variable to run the tests:
+
+```
+MYSQL_PORT_B=3307
+```
+
+This tells the tests that the second database is running on a different port.
+
+You may also set the log level variable to increase or decrease logging:
+
+```
+LOG_LEVEL=notice
+```
+
+In Xcode, edit the `fluent-mysql-driver` scheme to add env variables. In the terminal, use `export`. 
+
+## Xcode
+
+To open the project in Xcode:
+
+- Clone the repo to your computer
+- Drag and drop the folder onto Xcode
+
+You can then run the unit tests in Xcode by pressing `CMD+U`. 
+
+## SPM
+
+To develop using SPM, open the code in your favorite code editor. Use the following commands from within the project's root folder to build and test.
+
+```sh
+swift build
+swift test
+```
+
+## SemVer
+
+Vapor follows [SemVer](https://semver.org). This means that any changes to the source code that can cause
+existing code to stop compiling _must_ wait until the next major version to be included. 
+
+Code that is only additive and will not break any existing code can be included in the next minor release.
