 Assuming your PostgreSQL database user is called `postgres`, first authenticate as the database user with:
 
-    su - postgres
-    # Or, if your system uses sudo to get administrative rights
-    sudo -u postgres bash
+```sh
+su - postgres
+# Or, if your system uses sudo to get administrative rights
+sudo -u postgres bash
+```
 
 Then, create a postgres user and a database with:
 
-    # this will prompt for a password for the new user
-    createuser --pwprompt synapse_user
+```sh
+# this will prompt for a password for the new user
+createuser --pwprompt synapse_user
 
-    createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse
+createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse
+```
 
 The above will create a user called `synapse_user`, and a database called
 `synapse`.
