+Preview office documents (DOCX, XLSX, PPTX, macro-enabled DOCM, XLSM,
+PPTM, legacy DOC, XLS, PPT, and ODT, ODS, ODP, ODG) directly in the
+browser, including chatter attachments.
+
+The document is converted to PDF on the Odoo server using LibreOffice in
+headless mode and rendered with Odoo's native PDF.js viewer. Nothing
+leaves your server: no external viewer service (Microsoft Office Online,
+Google Docs) is involved, which makes this suitable for sensitive
+documents.
+
+Converted PDFs are cached on disk (keyed by document checksum), so each
+document is only converted once. The *Download* button still downloads
+the original file, not the converted PDF.

+
+Installation
+============
+
+LibreOffice must be installed on the Odoo server and the ``libreoffice``
+binary must be available in the PATH of the Odoo process:
+
+::
+
+   apt-get install libreoffice
+
+On Odoo.sh, LibreOffice is already available by default.
+
+If LibreOffice is not available, the module still installs, but the
+preview button is simply not shown for office files (the availability is
+exposed to the web client through the session info).
+
+Usage
+=====
+
+1. Attach an office file (e.g. an ``.xlsx``) to any record with a
+   chatter, or send it in a message.
+2. Click on the attachment thumbnail.
+3. The file opens in the standard Odoo file viewer, rendered as PDF.
+
