You can install JSW CRM like any other component.

Go to System->Install Extension and choose Upload package file.

The component is pretty large, about 9 mb, on most of the hosting packages that should not be a problem.
Otherwise look at the next video if that is a problem.

After the installation of JSW CRM is successful, create your first category.

A new category has some settings:

• What kind of pages contains the category?
  Choose the standard SEO setting of the category for new items. This setting can be changed on the item you create if you want.
  So, a category can contain items with different SEO settings.
  
  
• If the category contains items with a video or for example, a MP3 file, should this be shown on top or below the description?
  
  
• How should the images of the items be displayed? You can set a standard layout for a item in  various layouts (7).
  Every new item gets this layout as standard, but you can override it per item.
  
  
• If the items in the category contain maps, you can set the standard start-location of the map form for new items.
  handy!
  
  
• Who can see the category?
  Set the user rights (which users can see the category) of the category. 
  All items and sub-categories below get the same user rights of the category.
