+## Liquibase ##
+
+Liquibase allows you to run certain migrations depending on the dmbs you are executing the migration on.
+This can be done as follows:
+```yaml
+  - changeSet:
+      - id: 3-1
+      - author: "Liam Clark"
+      - preconditions:
+            dbms: "h2"
+      - changes:
+            - createSequence:
+                sequenceName: "HIBERNATE_SEQUENCE"
+```
+
+The names of the dmbs liquibase expects can be found [here](https://www.liquibase.org/databases.html)
+
