 You should normally only change the `DB_EXTERNAL` parameters then rollback and re-run the migrations (by default the API is assuming that it runs on two SQLite databases). To do so, find the root directory of `flexiapi` (normally under `/opt/belledonne-communications/share/flexisip-account-manager`), authenticate as your web user (`www-data` or `apache`) and run rollback and migrate (all the content will be destroyed, we recommend to do always do backup of your databases before running any migrations):

+php artisan migrate:rollback

 ### 5. Packaging

 To build a rpm package on centos7:

 make rpm

 To build a rpm package with docker:
 
-    docker run -v $PWD:/home/bc -it gitlab.linphone.org:4567/bc/public/flexisip-account-manager/bc-dev-centos:7 make rpm
+```bash
+docker run -v $PWD:/home/bc -it gitlab.linphone.org:4567/bc/public/flexisip-account-manager/bc-dev-centos:7 make rpm

 GitLab is running the command above using `make rpm-dev`, this also install all the required dependencies to run `phpunit` properly (they are disabled by default to save space in the final rpm file).
