+STATS
+=====
+
+This builtin script displays information and statistics for the currently
+played file. It is enabled by default if mpv was compiled with Lua support.
+It can be disabled entirely using the ``--load-stats-overlay=no`` option.
+
+Usage
+-----
+
+The following key bindings are active by default unless something else is
+already bound to them:
+
+====   ==============================================
+i      Show stats for a fixed duration
+I      Toggle stats (shown until toggled again)
+====   ==============================================
+
+While the stats are visible on screen the following key bindings are active,
+regardless of existing bindings. They allow you to switch between *pages* of
+stats:
+
+====   ==================
+1      Show usual stats
+2      Show frame timings
+====   ==================
+
+Font
+~~~~
+
+For optimal visual experience, a font with support for many font weights and
+monospaced digits is recommended. By default, the open source font
+`Source Sans Pro <https://github.com/adobe-fonts/source-sans-pro>`_ is used.
+
+Configuration
+-------------
+
+This script can be customized through a config file ``lua-settings/stats.conf``
+placed in mpv's user directory and through the ``--script-opts`` command-line
+option. The configuration syntax is described in `ON SCREEN CONTROLLER`_.
+
+Configurable Options
+~~~~~~~~~~~~~~~~~~~~
+
+``key_oneshot``
+    Default: i
+``key_toggle``
+    Default: I
+
+    Key bindings to display stats.
+
+``key_page_1``
+    Default: 1
+``key_page_2``
+    Default: 2
+
+    Key bindings for page switching while stats are displayed.
+
+``duration``
+    Default: 4
+
+    How long the stats are shown in seconds (oneshot).
+
+``redraw_delay``
+    Default: 1
+
+    How long it takes to refresh the displayed stats in seconds (toggling).
+
+``persistent_overlay``
+    Default: false
+
+    When false, other scripts printing text to the screen can overwrite the
+    displayed stats. When true, displayed stats are persistently shown for the
+    respective duration. This can result in overlapping text when multiple
+    scripts decide to print text at the same time.
+
+``plot_perfdata``
+    Default: true
+
+    Show graphs for performance data (page 2).
+
+``plot_vsync_ratio``
+    Default: true
+``plot_vsync_jitter``
+    Default: true
+
+    Show graphs for vsync and jitter values (page 1). Only when toggled.
+
+``flush_graph_data``
+    Default: true
+
+    Clear data buffers used for drawing graphs when toggling.
+
+``font``
+    Default: Source Sans Pro
+
+    Font name. Should support as many font weights as possible for optimal
+    visual experience.
+
+``font_mono``
+    Default: Source Sans Pro
+
+    Font name for parts where monospaced characters are necessary to align
+    text. Currently, monospaced digits are sufficient.
+
+``font_size``
+    Default: 8
+
+    Font size used to render text.
+
+``font_color``
+    Default: FFFFFF
+
+    Font color.
+
+``border_size``
+    Default: 0.8
+
+    Size of border drawn around the font.
+
+``border_color``
+    Default: 262626
+
+    Color of drawn border.
+
+``alpha``
+    Default: 11
+
+    Transparency for drawn text.
+
+``plot_bg_border_color``
+    Default: 0000FF
+
+    Border color used for drawing graphs.
+
+``plot_bg_color``
+    Default: 262626
+
+    Background color used for drawing graphs.
+
+``plot_color``
+    Default: FFFFFF
+
+    Color used for drawing graphs.
+
+Note: colors are given as hexadecimal values and use ASS tag order: BBGGRR
+(blue green red).
+
+Different key bindings
+~~~~~~~~~~~~~~~~~~~~~~
+
+A different key binding can be defined with the aforementioned options
+``key_oneshot`` and ``key_toggle`` but also with commands in ``input.conf``,
+for example::
+
+    e script-binding stats/display-stats
+    E script-binding stats/display-stats-toggle
+
+Using ``input.conf``, it is also possible to directly display a certain page::
+
+    i script-binding stats/display-page-1
+    e script-binding stats/display-page-2
