If you've used the Quickstart, you will not need to do this as it's already been done for you.
Important: Contrary to the "normal" Joomla way of doing things, most of the Jomres functionality is accessed via the front end, therefore you will need to enable the Login module so that you and/or other property manager's can log in and make any changes they need.
This page assumes that you've completed the installation by running install_jomres.php. If you haven't, you must perform that step first.
If you are just getting started with Jomres then you will probably want to add a menu option from your main menu to the Jomres Component.
In the CMS administrator's area use the top toolbar to navigate: Menu -> Main menu. Click the New icon, then choose Component from the Components panel. You will be in the "Add Menu Item :: Component " screen. Enter a description (I recommend Bookings for now) and choose Jomres from the Select list below and click Save.
Now you can go to the front end of your CMS installation and refresh it. You should have the Bookings option in the main menu. Log in as admin to administer your properties.
What a user sees when they view Jomres depends on
1. their status with the system and
2. how you've configured certain Jomres modules.
If a user is a non-authorised user, then it is expected that in most instances they will arrive in the component either via a link in one of your menus or via a search module. If you only have one property on the system then it's probably not practical to install any of the search modules and you can limit yourself to having only the link in the menu. If you have more than one property then it is recommended that you install one of the search modules and encourage visitors to use that to locate a property.
Authorised users would be better served by having a link in a menu, for example in the user menu, that they can click on.
