=== Applications registration ===
An App developer can register a new application into Mozilla Presence
An application is defined by:
* a domain
* an email
* a name
* a description
Registering a new application is done in 3 steps
# validation of the domain ownership
# attribution of a unique application ID
# activation of presence notifications
'''Domain Ownership Validation'''
Mozilla Presence provides a web page where an application developer can connect
by logging with her persona account. Once logged in, the developer can fill a
form with a domain, name and description of the application to register.
Mozilla presence generates a unique key of 1024 characters, the developer needs
to place in this URL: ''http://<domain>/__presence'' in a plain/text file that
can be reached pubicly.
Once the key is placed, the developer can hit a '''Verify''' button.
Mozilla presence will then visit ''http://<domain>/__presence'' to verify
that the domain is owned by the developer.
