Signing in
==========

You need to sign in before you can browse the catalog.
This page explains what you can do once you are in, and how to
change the look of the application.

   The sign-in screen.

.. note::

   Some screenshots in this guide show a "DEV LOGIN" label in the
   top bar.
   It only appears on test installations and does not appear on
   yours.

Sign in
-------

#. Open the catalog address your team gave you.
#. Select **Sign in**.
#. Use your usual company login.

You return to the catalog when the login is done.
To leave, open the menu with your name and select **Sign out**.

What you are allowed to do
--------------------------

Your role decides what you can do.
There are three roles, and one person can hold several.

Reader
   You can search and read every decision and erratum.
   You see the status of each one, but you cannot decide.
   Where a reviewer would see **Accept** and **Reject**, you see
   "Only reviewers can approve this."

Reviewer
   You can do everything a reader can, and you can accept or reject
   decisions and verify or reject errata.
   See :doc:`reviewing`.

Operator
   You can do everything a reader can, and you can ask the catalog
   to read its sources again.
   See :doc:`sources-page`.
   Being an operator does not make you a reviewer.

Roles are set by your administrators, not in the application.
If you cannot do something you expect to, ask them.

Change the theme
----------------

#. Open the menu with your name (on a phone, the **Open menu**
   button).
#. Under **Theme**, choose **Light**, **Dark** or **System**.

**System** follows your device setting.
The choice is remembered in your browser.
