-# Metadata and privacy
-
-Metadata consist of information that characterizes data.
-Metadata are used to provide documentation for data products.
-In essence, metadata answer who, what, when, where, why, and how about
-every facet of the data that are being documented.
-
-Metadata within a file can tell a lot about you.
-Cameras record data about when a picture was taken and what
-camera was used. Office documents like PDF or Office automatically adds
-author and company information to documents and spreadsheets.
-Maybe you don't want to disclose those information.
-
-This is precisely the job of mat2: getting rid, as much as possible, of
-metadata.
-
-mat2 provides:
-- a library called `libmat2`;
-- a command line tool called `mat2`,
-- a service menu for Dolphin, KDE's default file manager
-
-If you prefer a regular graphical user interface, you might be interested in
-[Metadata Cleaner](https://metadatacleaner.romainvigier.fr/), which is using
-`mat2` under the hood.
-
-# Requirements
-
-- `python3-mutagen` for audio support
-- `python3-gi-cairo` and `gir1.2-poppler-0.18` for PDF support
-- `gir1.2-gdkpixbuf-2.0` for images support
-- `gir1.2-rsvg-2.0` for svg support
-- `FFmpeg`, optionally, for video support
-- `libimage-exiftool-perl` for everything else
-- `bubblewrap`, optionally, for sandboxing
-
-Please note that mat2 requires at least Python3.5.
-
-# Requirements setup on macOS (OS X) using [Homebrew](https://brew.sh/)
-
-```bash
-brew install exiftool cairo pygobject3 poppler gdk-pixbuf librsvg ffmpeg
-```
-
-# Running the test suite
-
-```bash
-$ python3 -m unittest discover -v
-```
-
-And if you want to see the coverage:
-
-```bash
-$ python3-coverage run --branch -m unittest discover -s tests/
-$ python3-coverage report --include -m --include /libmat2/*'
-```
-
-# How to use mat2
-
-```
-usage: mat2 [-h] [-V] [--unknown-members policy] [--inplace] [--no-sandbox]
-            [-v] [-l] [--check-dependencies] [-L | -s]
-            [files [files ...]]
-
-Metadata anonymisation toolkit 2
-
-positional arguments:
-  files                 the files to process
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -V, --verbose         show more verbose status information
-  --unknown-members policy
-                        how to handle unknown members of archive-style files
-                        (policy should be one of: abort, omit, keep) [Default:
-                        abort]
-  --inplace             clean in place, without backup
-  --no-sandbox          Disable bubblewrap's sandboxing
-  -v, --version         show program's version number and exit
-  -l, --list            list all supported fileformats
-  --check-dependencies  check if mat2 has all the dependencies it needs
-  -L, --lightweight     remove SOME metadata
-  -s, --show            list harmful metadata detectable by mat2 without
-                        removing them
-```
-
-Note that mat2 **will not** clean files in-place, but will produce, for
-example, with a file named "myfile.png" a cleaned version named
-"myfile.cleaned.png".
-
-## Web interface
-
-It's possible to run mat2 as a web service, via
-[mat2-web](https://0xacab.org/jvoisin/mat2-web).
-
-If you're using WordPress, you might be interested in [wp-mat](https://git.autistici.org/noblogs/wp-mat)
-and [wp-mat-server](https://git.autistici.org/noblogs/wp-mat-server).
-
-## Desktop GUI
-
-For GNU/Linux desktops, it's possible to use the
-[Metadata Cleaner](https://gitlab.com/rmnvgr/metadata-cleaner) GTK application.
-
-# Supported formats
-
-The following formats are supported: avi, bmp, css, epub/ncx, flac, gif, jpeg,
-m4a/mp2/mp3/…, mp4, odc/odf/odg/odi/odp/ods/odt/…, off/opus/oga/spx/…, pdf,
-png, ppm, pptx/xlsx/docx/…, svg/svgz/…, tar/tar.gz/tar.bz2/tar.xz/…, tiff,
-torrent, wav, wmv, zip, …
-  
-# Notes about detecting metadata
-
-While mat2 is doing its very best to display metadata when the `--show` flag is
-passed, it doesn't mean that a file is clean from any metadata if mat2 doesn't
-show any. There is no reliable way to detect every single possible metadata for
-complex file formats.
-
-This is why you shouldn't rely on metadata's presence to decide if your file must
-be cleaned or not.
-
-# Notes about the lightweight mode
-
-By default, mat2 might alter a bit the data of your files, in order to remove
-as much metadata as possible. For example, texts in PDF might not be selectable anymore,
-compressed images might get compressed again, …
-Since some users might be willing to trade some metadata's presence in exchange
-of the guarantee that mat2 won't modify the data of their files, there is the
-`-L` flag that precisely does that.
