+### Database Migrations
+
+Migrations are stored in [src/main/migrations](src/main/migrations) and handled by typeorm.
+
+To auto-generate a migration:  
+`node_modules/.bin/typeorm migration:generate -c <connection name>`
+
+To create an empty creation which can be filled with custom migration code:  
+`node_modules/.bin/typeorm migration:create -c <connection name>`
+
+To run migrations:  
+`node_modules/.bin/typeorm migration:run -c <connection name>`  
+This is also pre-defined in the npm script `typeorm:migrate`.
