+* A TUI wrapper for local play of the game of Tak
+
+** Building
+
+Clone the repo, issue `cargo build` or and enjoy (?)
+
+** Usage
+
+Takwrap supports local play, undo, and starting variant and game
+exporting to PTN. See `takwrap -h` for options and details.
+
+Note in particular that `takwrap` supports the following alternate
+starting configurations, which are embedded in the exported PTN file
+as `[Variant XXX]`.
+
+- CPSn, counter-play start with n=1 is the default
+  White places a black flat, then black places a white flat. This
+  repeats n times, after which normal play resumes.
+
+- FCS, forbidden corner start
+  CPS1 but white may not place the black flat in a corner
+
+- FES, forbidden edge start
+  CPS1 but white may not place the black flat on an edge
+
+- TPS, two ply start
+  White places two black flats, then black places a white flat and
+  normal play resumes.
+
+- CZS, Czech start
+  White places a black flat, then normal play resumes
+
+** Interfacing with engines
+
+Takwrap does not have computer opponents built in, but instead allows
+interfacing with external engine programmes with the `-e` parameter.
+It expects the name of an executable in the path which accepts the
+name of a file with a game-state in PTN, and which returns a single,
+valid move.
+
+See the file `wrap_taktician` for an example of utilising [[https://github.com/nelhage/taktician][Taktician]]
+for this purpose.
+
+Note that the engine is expected to respect the `[Variant XXX]` line
+in the PTN game-state, so expect breakage with anything but the
+default.
