 Calibre-Web README
 ==================
 
-This Ansible role installs
-`Calibre-Web <https://github.com/janeczku/calibre-web#readme>`_ as a modern
-client-server alternative to Calibre, for your
-`Internet-in-a-Box (IIAB) <https://internet-in-a-box.org>`_.
+Calibre-Web provides a clean interface for browsing, reading and downloading
+e-books using an existing Calibre database.  Teachers can upload e-books,
+adjust e-book metadata, and create custom e-book collections ("bookshelves"):
+https://github.com/janeczku/calibre-web#about
 
-Calibre-Web provides a clean web interface for students to browse, read and
-download e-books using a
-`Calibre-compatible database <https://manual.calibre-ebook.com/db_api.html>`_.
+This Ansible role installs Calibre-Web as part of your Internet-in-a-Box (IIAB)
+as a possible alternative to Calibre.
 
-Teachers upload e-books, adjust e-book metadata, and create custom "bookshelf"
-collections — to help students build the best local community library!
+*WARNING: Calibre-Web depends on Calibre's own* ``/usr/bin/ebook-convert`` *program,
+so we strongly recommend you also install Calibre during your IIAB
+installation!*
 
-**NEW AS OF JANUARY 2024:** `IIAB's experimental new version of Calibre-Web <https://github.com/iiab/calibre-web/wiki>`_
-**also lets you add YouTube and Vimeo videos (and local videos, e.g. from
-teachers' phones) to expand your indigenous/local/family learning library!**
-
-.. image:: https://www.yankodesign.com/images/design_news/2019/05/221758/luo_beetle_library_8.jpg
-
-🍒 GURU TIPS 🍒
-
-* Calibre-Web takes advantage of Calibre's own `/usr/bin/ebook-convert
-  <https://manual.calibre-ebook.com/generated/en/ebook-convert.html>`_ program
-  if that's installed — so consider also installing
-  `Calibre <https://calibre-ebook.com/whats-new>`_ during your IIAB
-  installation — *if you tolerate the weighty ~1 GB (of graphical OS libraries)
-  that Calibre mandates!*
-
-* If you choose to also install Calibre (e.g. by running
-  ``sudo apt install calibre``) then you'll get useful e-book
-  importing/organizing tools like
-  `/usr/bin/calibredb <https://manual.calibre-ebook.com/generated/en/calibredb.html>`_.
-
-Install It
-----------
-
-Install Calibre-Web by setting these 2 variables in
-`/etc/iiab/local_vars.yml <https://wiki.iiab.io/go/FAQ#What_is_local_vars.yml_and_how_do_I_customize_it%3F>`_::
-
-  calibreweb_install: True
-  calibreweb_enabled: True
-
-Then install IIAB (`download.iiab.io <https://download.iiab.io>`_).  Or if
-IIAB's already installed, run::
-
-  cd /opt/iiab/iiab
-  sudo ./runrole calibre-web
-
-NOTE: Calibre-Web's Ansible role (playbook) in
-`/opt/iiab/iiab/roles <https://github.com/iiab/iiab/tree/master/roles>`_ is
-``calibre-web`` which contains a hyphen — *whereas its Ansible variables*
-``calibreweb_*`` *do NOT contain a hyphen!*
+Please note Calibre-Web's Ansible playbook is ``/opt/iiab/iiab/roles/calibre-web``
+whereas its Ansible variables ``calibreweb_*`` do **not** include the dash,
+per Ansible recommendations.
 
 Using It
 --------
 
-Try Calibre-Web on your own IIAB by browsing to http://box/books (or
-http://box.lan/books).
+After installation, try out Calibre-Web at http://box/books (or box.lan/books).
 
-*Students* access it without a password (to read and download books).
-
-*Teachers* add and arrange books using an administrative account, by clicking
-**Guest** then logging in with::
+Typically students access it without a password (to read and download books)
+whereas teachers add books using an administrative account, as follows::
 
   Username: Admin
   Password: changeme
 
-🍒 GURU TIPS 🍒
+If the default configuration is not found, the Calibre-Web server creates a
+new settings file with calibre-web's own default administrative account::
 
-* If Calibre-Web's configuration file (app.db) goes missing, the administrative
-  account will revert to::
+  Username: admin
+  Password: admin123
 
-    Username: admin
-    Password: admin123
+Backend
+-------
 
-* If you lose your password, you can change it with the
-  ``-s [username]:[newpassword]`` command-line option:
-  https://github.com/janeczku/calibre-web/wiki/FAQ#what-do-i-do-if-i-lose-my-admin-password
+You can manage the backend Calibre-Web server with these systemd commands::
+
+  systemctl enable calibre-web
+  systemctl restart calibre-web
+  systemctl status calibre-web
+  systemctl stop calibre-web
 
 Configuration
 -------------
 
-To configure Calibre-Web browse to http://box/books then click **Guest** to log
-in as user **Admin** (default passwords above!)
+To configure Calibre-Web, log in as user 'Admin' then click 'Admin' on top.
+Check 'Configuration' options near the bottom of the page.
 
-Then click the leftmost **Admin** button to administer — considering all 3
-**Configuration** buttons further below.
-
-These critical settings are stored in::

+Your e-book metadata is stored in a Calibre-style database::

-
 See also::
 
   /library/calibre-web/metadata_db_prefs_backup.json
 
-Finally, take note of Calibre-Web's
-`FAQ <https://github.com/janeczku/calibre-web/wiki/FAQ>`_ and official docs on
-its
-`Runtime Configuration Options <https://github.com/janeczku/calibre-web/wiki/Configuration>`_
-and

-
-Backend
--------
-
-You can manage the backend Calibre-Web server with systemd commands like::
-
-  systemctl status calibre-web
-  systemctl stop calibre-web
-  systemctl restart calibre-web
-
-Run all commands
-`as root <https://unix.stackexchange.com/questions/3063/how-do-i-run-a-command-as-the-system-administrator-root>`_.
-
-Errors and warnings can be seen if you run::
-
-  journalctl -u calibre-web
-
-Log verbosity level can be
-`adjusted <https://github.com/janeczku/calibre-web/wiki/Configuration#logfile-configuration>`_
-within Calibre-Web's **Configuration > Basic Configuration > Logfile
-Configuration**.
-
-Finally, http://box/live/stats (Calibre-Web's **About** page) can be a very
-useful list of ~42 `Calibre-Web dependencies <https://github.com/janeczku/calibre-web/wiki/Dependencies-in-Calibre-Web-Linux-and-Windows>`_
-(mostly Python packages, and the version number of each that's installed).
+Finally, take note of Calibre-Web's `FAQ <https://github.com/janeczku/calibre-web/wiki/FAQ>`_ and official docs on its `Runtime Configuration Options <https://github.com/janeczku/calibre-web/wiki/Configuration>`_ and `Command Line Interface <https://github.com/janeczku/calibre-web/wiki/Command-Line-Interface>`_.
 
 Back Up Everything
 ------------------
 
 Please back up the entire folder ``/library/calibre-web`` before upgrading —
-as it contains your Calibre-Web content **and** configuration settings!
+as it contains your Calibre-Web content **and** settings!
 
 Upgrading
 ---------
 
-Please see our `new/automated upgrade technique (iiab-update) <https://github.com/iiab/calibre-web/wiki#upgrading>`_
-introduced in July 2024.
+Reinstalling Calibre-Web automatically upgrades to the latest version if your
+Internet-in-a-Box (IIAB) is online.
 
-But first: back up your content **and** configuration settings, as outlined
-above!
+But first: back up your content **and** settings, as explained above.

-/library/calibre-web/xklb-metadata.db out of the way.**
-
-RECAP: Either way, "reinstalling" Calibre-Web automatically installs the latest
-version — so long as your Internet-in-a-Box (IIAB) is online.  Most people
-should stick with the new ``iiab-update`` technique above.  However if you must

+e-book metadata!  Then run**::
