+Configuration
+-------------
+You can start your _sdtui.conf_ file with the following snippet:
+
+ [Settings]
+ center-search = true     # Ensure visibility of preceding entries?
+ underline-last = false   # Underline the last line of entries?
+ hl-common-prefix = true  # Highlight the longest common prefix?
+ watch-selection = true   # Watch X11 selection for changes?
+
+The _watch-selection_ option makes the application watch the X11 PRIMARY
+selection for changes and automatically search for any selected text.
+This feature requires XCB.  Wayland is currently unsupported,
+but would require a compositor supporting the wlr-data-control protocol.
+Luckily, some compositors, such as Sway, synchronize selections with Xwayland.
+
+To set up automatically loaded dictionaries, use the following scheme:
+
+[subs="normal"]
+ [Dictionaries]
+ _name 1_ = __~/path/to/dict.ifo__
+ _name 2_ = __~/another/dict.ifo__
+
+The left-hand side keys define their appearance in the tab bar.
+
+Finally, to make the program look nicer in 256color black-on-white terminals,
+rather than rely on the universal default, try:
+
+ [Colors]
+ header = reverse
+ header-active = ul
+ search = ul
+ even = 16 231
+ odd = 16 255
+
+Terminal attributes are accepted in a format similar to that of *git-config*(1),
+only named colours aren't supported.
+
+Extensions
+----------
+Because the StarDict file format is a bit of a clusterfuck with regard to
+collation of dictionary entries, this software introduces an additional,
+optional "collation" field into the '.ifo' file.  When *sdtui* discovers this
+field while reading a dictionary, it automatically reorders the index according
+to that locale (e.g., "cs_CZ").  This operation may take a little while,
+in the order of seconds.
