# Working with the Available Software sites

The Available Software Sites dialog allows you to define the software sites that are consulted when browsing for available software or updating the system. To manage the list of sites used by the system:

1. Click Help > Software Updates ... and select the Available Software page. This page shows you the items that are available for installation.
2. Click the Manage Sites... button to see the list of sites that are used to gather the available software and search for updates.
3. All sites registered in the system are shown in the list. Sites with a check mark are those that are used to search for updates and browse available software. Sites without a check mark are not currently used.
4. Select a site and click Properties to see information about the site, such as its location, name, or description. This dialog may also contain status information about the site, such as when the site is not available on the network.
5. You may check or uncheck a site in order to control whether it is used for updates and add-ons. For example, you may wish to uncheck a site that is temporarily not available or experiencing network problems in order to speed up the search for updates.

You may change the sites that are used by the system in several ways:

- To add sites to the system:
  - Click Add... to enter the location of a new site.
  - You may check mark an unchecked site it in order to make it available to the system.
  - Click Import... to import a list of sites that was previously exported to a file.
- To remove sites from the system:
  - Remove the check mark from the site if you want to temporarily stop using the site. This will keep the site in the list so that you can check mark it later.
  - Click Remove to remove the site from the list of sites.
- Click Export... to save the list of sites to a file. This is useful for sharing site lists with other users or across multiple Eclipse installations.
