 # authd
 
-`authd` is a token-based authentication micro-service based on [libipc][libipc].
+`authd` is a (JWT) token-based authentication micro-service based on [libipc][libipc].
+`authd` stores users (login, encrypted password), their profile (arbitrary data) and their *permissions*.
+For example, `authd` is used by [dnsmanagerd][dnsmanagerd] to handle authentication and permissions.
 
-> TODO: explain basic concepts behind `authd`.
+No SQL, the entire database is stored in plain files, thanks to [the DODB database library][dodb].
+
+The [netlibre service][netlibre] is the first to use `authd` in a real-life deployment.

-> TODO: documentation on how to deploy, including with the mail server and tools.
+For a more extensive documentation, please read the manual for both [authd][authdmanual] and [authctl][authctlmanual].
 
-### Users storage
+See the [configuration example][configuration-example] to avoid long command-line parameters.
 
-The storage directory will default to `./storage`.
+Also, extensive usage examples are available in the makefiles.
 
-No SQL database, database management system or other kind of setup is required to run authd and store users.
+## Administration
 
-To migrate an instance of authd, a simple copy of the storage directory will be enough.
+```sh
+# First user in the database is an administrator.
+authctl bootstrap name email
+```
 
-### Administrating users
+```sh
+# Add a user:
+authctl user add login email
+```
 
-> TODO: document how to manage users through `authctl`.
+For a comprehensive list of available commands, please read the [authctl manual][authctlmanual].
 
+## Real-life deployment
 
-## APIs
+For a real-life deployment, you might want to enable registration.
+In this case, you need to get a `mailer` application to send template emails.
+See [an example of such application][mailer].

 A simple error message is given instead of specific messages for each recurring error.
 In the same time, some exceptions (such as **AdminAuthenticationException**) are used a few times for the same kind of errors.

-
-- On login: inform the user he doesn't have an email address.
-  This happens when the user was migrated.
-
 ### Structures, not classes
 
 Maybe in some cases, it could be great to use structures instead of classes.
