+- `admin`: Full system access
+- `events_admin`: Can manage conferences and related resources
+- `shift_coordinator`: Can manage session assignments

+#### Managing Roles with Rake Tasks
 
-## Tips and Tricks
+You can also use the following rake tasks to manage user roles from the command line:
 
-### Helpful `rails` tasks
+```bash
+# View all users with special roles
+rake admin:list
 
-By running `bin/rails <command>` you can trigger some helpful actions, such as
+# List all events admin users
+rake admin:list_events_admins
 
-- `rails c[onsole]`: Start interactive ruby shell
-- `rails db`: Start sqlite shell with the currently used DB
-- `rails db:migrate`: Run pending DB migrations, automatically done by docker image on start
-- `rails db:seed` (Re-)import DB seeds from `db/seeds.rb`
-- `rails secret` generate a random secret, e.g. for `secret_key_base`
-- `rails generate` Powerful tool to generate boilerplate, run it to see list of options
+# Assign roles
+rake admin:make_admin[user@example.com]
+rake admin:make_events_admin[user@example.com]
+rake admin:make_shift_coordinator[user@example.com]
 
-### In `rails console`
+# Remove roles
+rake admin:remove_admin[user@example.com]
+rake admin:remove_events_admin[user@example.com]
+rake admin:remove_shift_coordinator[user@example.com]
+```
 
-- Manually trigger sync job
-  ~~~ruby
-  FetchConferenceDataJob.perform_now("38c3")
-  ~~~
+### Conference Management
 
-- Promote user to shiftcoordinator
-  ~~~ruby
-  User.find_by(name:"username_here").update(shiftcoordinator: true)
-  ~~~
+#### Adding a New Conference
+
+Conferences can be added through the admin interface:
+1. Navigate to `/admin/conferences`
+2. Click on "Add New Conference"
+3. Fill in the basic information (name, slug, dates, time zone)
+4. Select the appropriate import job class (e.g., Pretalx, re:publica)
+5. Provide the required data fields for the selected import method
+6. Save the conference to initiate the data import
+
+#### Importing and Updating Conference Data
+
+Conference data can be imported and updated through the admin interface:
+1. Navigate to the conference details page in admin
+2. Click on "Run Import Again" to start a new import
+3. The import process runs in the background with real-time progress tracking
+4. View the import history to see past imports and any errors
+
+#### Setting Relevant Stages
+
+The admin interface provides a dedicated page for managing which stages are relevant:
+1. Navigate to the conference details page in admin
+2. Click on "Manage Relevant Stages"
+3. Check the boxes for stages that should be considered relevant
+4. Save your selection
+
+#### Prioritizing Stages
+
+You can set the display order of stages through stage weights. Higher weights push stages down in the listing order:
+
+```ruby
+Stage.where(name: "Saal 1").update(weight: 10)
+Stage.where(name: "Saal GLITCH").update(weight: 20)
+Stage.where(name: "Saal ZIGZAG").update(weight: 30)
+```
