 Brutal Maze
 ===========
 
-Brutal Maze is a hack and slash game with fast-paced action and a minimalist
-art style.

-The game features a trigon trapped in an infinite maze. As our hero tries to
-escape, the maze's border turns into aggressive squares trying to stop him.
-Your job is to help the trigon fight against those evil squares and find a way
-out (if there is any). Be aware that the more get killed, the more will show up
-and our hero will get weaker when wounded.

+* Easily customizable via INI file format.
+* Recordable in JSON (some kind of silent screencast).
+* Remote control through TCP/IP socket (can be used in AI researching).
 
 Installation
 ------------
 
-Brutal Maze is written in Python and is compatible with both version 2 and 3.
-The installation procedure should be as simply as follow:
+Brutal Maze is written in Python and is compatible version 3.6 and above.
+The installation procedure should be as simple as follows:
 
-* Install Python and `pip <https://pip.pypa.io/en/latest/>`_. Make sure the
-  directory for `Python scripts <https://docs.python.org/2/install/index.html#alternate-installation-the-user-scheme>`_
+* Install Python and pip_.  Make sure the directory for `Python scripts`_
   is in your ``$PATH``.
 * Open Terminal or Command Prompt and run ``pip install --user brutalmaze``.
-  Now you can launch the game by running the command ``brutalmaze``.
 
-For more information, see the `Installation <https://github.com/McSinyx/brutalmaze/wiki/Installation>`_
-from Brutal Maze wiki.
+For more information, see Installation_ page from the documentation.
+
+After installation, you can launch the game by running the command
+``brutalmaze``.  Below are the default bindings, which can be configured as
+shown in the next section:
+
+F2
+   New game.
+``p``
+   Toggle pause.
+``m``
+   Toggle mute.
+``a``
+   Move left.
+``d``
+   Move right.
+``w``
+   Move up.
+``s``
+   Move down.
+Left Mouse
+   Long-range attack.
+Right Mouse
+   Close-range attack, also dodge from bullets.
+
+Additionally, Brutal Maze also supports touch-friendly control.  In this mode,
+touches on different grid (empty, wall, enemy, hero) send different signals
+(to guide the hero to either move or attack, or start new game).  Albeit it is
+implemented using *mouse button up* event, touch control is not a solution for
+mouse-only input, but an attempt to support mobile GNU/Linux distribution such
+as postmarketOS, i.e. it's meant to be played using two thumbs :-)
 
 Configuration
 -------------
 
 Brutal Maze supports both configuration file and command-line options.
-Apparently one can change settings for graphics and control in the config file
-and set graphics options using in CLI. These settings are read in the following
-order:
+Apparently, while settings for graphics, sound and socket server can be set
+either in the config file or using CLI, keyboard and mouse bindings are limited
+to configuration file only.
 
-0. Default configuration [0]_
-1. System-wide configuration file [1]_
-2. Local configuration file [1]_
-3. Manually set configuration file [2]_
+Settings are read in the following order:

+2. Local configuration file [2]_
+3. Manually set configuration file [3]_

-   for more info.
-.. [2] If specified by ``brutalmaze --config PATH``.
+Remote control
+--------------
+
+If you enable the socket server [4]_, Brutal Maze will no longer accept
+direct input from your mouse or keyboard, but wait for a client to connect.
+The I/O format is explained in details in the `Remote Control`_ page.
+
+Game recording
+--------------
+
+Either game played by human or client script can be recorded to JSON format.
+This can be enabled by setting the output directory to a non-empty string [5]_.
+Recordings can be played using Brutal Maze `HTML5 record player`_.
+
+Copying
+-------
+
+Brutal Maze's source code and its icon are released under GNU Affero General
+Public License version 3 or later. This means if you run a modified program on
+a server and let other users communicate with it there, your server must also
+allow them to download the source code corresponding to the modified version
+running there.
+
+This project also uses Tango color palette and several sound effects, whose
+authors and licenses are listed in the Copying_ page in our documentation.

+user config whose locations are shown above.  These files are listed as fallback
+of the ``--config`` option and their contents are fallback for other options
+(if they are absent default values are used instead).  We don't support control
+configuration via CLI because that is unarguably ugly.
+
+If ``--config`` option is set, Brutal Maze parse it before other command-line
+options.  Later-read preferences will override previous ones.

+Gameplay
+========
+
+Brutal Maze is a fast-paced hack and slash game which aims to bring players
+a frustrating, horror-like experience.  It tries to mimic real-life logic in
+a way that truly represents our loneliness, mortality and helplessness
+in the universe.
+
+The game features a solitary hero in a trigon shape who got lost in world of
+squares.  Unlucky for per, the squares have no intention to let their visitor
+leave in peace.  Together, they form a greater being called The Maze.
+Naturally, The Maze is dynamically and infinitely generated.  As our poor hero
+tries to find a way out, it releases its minions (we will call them *enemies*
+from here) to stop per.  Since The Maze *sees it all* and *knows it all*,
+it keeps creating more and more enemies for the hero to fight.  It also
+keeps track of which type of squares can do most damages to our trigon,
+in order to send out the most effective belligerents.
+
+Your mission is to help the hero go the furthest distance possible,
+while fighting those aggressive enemies.  Extra information below will
+give you a better understanding of what you fight and how you fight them.
+
+Hero
+----
+
+The hero is a regular trigon_ in Aluminium color (from `the Tango palette`_).
+Perse has the ability to attack and move (both horizontally and vertically)
+simultaneously.  However, close- and long-range attacks can't be stricken
+at the same time.  When swinging per blade, our hero may also avoid getting
+damages caused by per enemies' bullets.
+
+Like heroes in other hack and slash games, the trigon can heal too, but irony,
+per HP recovery rate decreases as perse gets wounded.  Been warned you have,
+bravery will only give you regrets.
+
+Enemies
+-------
+
+Enemies are put into hibernation and blend into The Maze at the time of their
+creation.  When the hero comes across, they become awake and show their
+(physical) colors.  Enemy of each color has an unique power as described below:
+
+Butter
+   May strike critical hits.
+
+Orange (also known as *Agent Orange*)
+   May prevent the hero from healing or blocking bullets.
+   Poisoned hero will be drawn as a square.
+
+Chocolate (a.k.a. *MDMA in Disguise*):
+   May make the hero high and shoot uncontrollably.
+   Still, Chocolate is good for your health (and so is MDMA).
+
+Chameleon
+   Invisible, only shows itself when attacking or being attacked.
+
+Sky Blue (a.k.a. *Lightning Sky*)
+   May immobilize the hero.  If this happen our hero can only see the enemies,
+   including Chameleons, on a blank background.  What a blessing in disguise!
+
+Plum (a.k.a. *Plum Wine*)
+   May replicate.  Very quickly.
+
+Scarlet Red (a.k.a. *Vampire's Eye*)
+   Moves faster and drains hero's HP.
+
+The possibility that an enemy attack with its special power increases when it's
+able to prove its effectiveness to The Maze.  In other words, the more a kind
+of enemy hit the hero, the more chance they *may* use their unique abilities.
+Lucky for you, squares are unitasking so they have to stop moving to perform
+attacks.  This slows them down a bit, however the ones which fall off the
+display will respawn elsewhere in The Maze.
+
+Attacks
+-------
+
+In this game, attack's damage is contingent on the distance between the
+attacker and its target.  The closer they are, the more damage is caused.
+There is at least an one-third-second delay between two attacks stricken
+by any character.
+
+Long-range Attacks
+^^^^^^^^^^^^^^^^^^
+
+While projectiles are often called *bullets* in the code and the documentation,
+they are more similar to stones propelled by slingshots, as they don't fly very
+far (about 6 times the width of an enemy).  Those fired by enemies can fly
+though walls but the ones shot by the hero turn the grid into a new enemy.
+A bullet is counted as hitting the target when the distance between the center
+of the two object is less than the circumradius of a cell.
+
+Close-range Attacks
+^^^^^^^^^^^^^^^^^^^
+
+It is needless to explain any further on how this kind of attack works, so we
+only provide the size of the characters for you to calculate when the strike
+can wound the target.  To do so, the attacker must *touch* its opponents, or
+simplistically, the distance between the central points of the two characters
+must not be any greater than the sum of their circumradiuses.  Do the
+calculations yourself, a square's side is a fifth of the walls', and covers the
+same area as a trigon.
+
+Specially, hero's closed-range attacks also block opponents' bullets.
+If this happens, the hero won't be able to attack in the next turn.
+
+Manual slashing
+^^^^^^^^^^^^^^^
+
+As the hero always follow the mouse, perse perform close-range attack
+while doing so.  Unlike the automatic ones, there isn't any delay between
+two manual slashings.

+Installation
+============
+
+Brutal Maze should run on Python version 3.6 and above.
+If you're using an Unix-like operating system, you're likely
+to have Python installed on your computer.  Otherwise, you can
+download it from python.org_.
+
+The game also uses multiple third-party libraries, which is recommended to
+be installed using ``pip``.  There is a detailed documentation about getting
+this package manager on pypa.io_.
+
+Install from PyPI
+-----------------
+
+For convenience reasons, every release of Brutal Maze is uploaded to the Python
+Package Index.  To either install or upgrade, open your terminal (on Windows:
+Command Prompt or PowerShell) and run::
+
+   pip install --user --upgrade brutalmaze
+
+This requires the `the user scheme`_ scripts directory to be
+in your environmental variable ``$PATH``.
+
+Install from Source
+-------------------
+
+If you want to tweak the game or contribute, clone the git repository::
+
+   git clone https://git.disroot.org/McSinyx/brutalmaze.git
+
+Then install it using ``pip``, like so::

+Remote Control
+==============
+
+Brutal Maze provides a INET (i.e. IPv4), STREAM (i.e. TCP) socket server which
+can be enabled in the config file or by adding the ``--server`` CLI flag.
+After binding to the given host and port, it will wait for a client to connect.
+Then, in each cycle of the loop, the server will send current details of
+each object (hero, walls, enemies and bullets), wait for the client to process
+the data and return instruction for the hero to follow.  Since there is no EOT
+(End of Transfer) on a socket, messages sent and received between server
+and client must must be strictly formatted as explained below.
+
+Server Output
+-------------
+
+First, the game will export its data to a byte sequence (which in this case,
+is simply a ASCII string without null-termination) of the length :math:`l`.
+Before sending the data to the client, the server would send the number
+:math:`l` padded to 7 digits.
+
+Below is the meta structure of the data::
+
+   <Map height (nh)> <Number of enemies (ne)> <Number of bullets (nb)> <Score>
+   <nh lines describing visible part of the maze>
+   <One line describing the hero>
+   <ne lines describing ne enemies>
+   <nb lines describing nb bullets>
+
+The Maze
+^^^^^^^^
+
+Visible parts of the maze with the width :math:`n_w` and the height :math:`n_h`
+are exported as a byte map of :math:`n_h` lines and :math:`n_w` columns.
+Any character other than 0 represents a blocking *cell*, i.e. a wall.
+
+To avoid floating point number in later description of other objects, each
+cell has the width (and height) of 100, which means the top left corner of
+the top left cell has the coordinates of :math:`(0, 0)` and the bottom right
+vertex of the bottom right cell has the coordinates of
+:math:`(100 n_w, 100 n_h)`.
+
+The Hero
+^^^^^^^^
+
+6 properties of the hero are exported in one line,
+separated by 1 space, in the following order:
+
+:Color:
+   The current HP of the hero, as shown in in the later section.
+:X-coordinate:
+   An integer within :math:`[0, 100 n_w]`.
+:Y-coordinate:
+   An integer within :math:`[0, 100 n_h]`.
+   Note that the y-axis points up-side-down instead of pointing upward.
+:Angle:
+   The direction the hero is pointing to in degrees,
+   cast to an integer from 0 to 360.  Same note as above
+   (the unit circle figure might help you understand this easier). 
+:Can attack:
+   0 for *no* and 1 for *yes*.
+:Can heal:
+   0 for *no* and 1 for *yes*.
+
+.. image:: images/unit-circle.png
+
+The Enemies
+^^^^^^^^^^^
+
+Each enemy exports these properties:
+
+:Color:
+   The type and the current HP of the enemy, as shown in the table below.
+:X-coordinate:
+   An integer within :math:`[0, 100 n_w]`.
+:Y-coordinate:
+   An integer within :math:`[0, 100 n_h]`.
+:Angle:
+   The direction the enemy is pointing to in degrees,
+   cast to a nonnegative integer.
+
+To shorten the data, each color (in the Tango palette) is encoded to a
+lowercase letter.  Different shades of a same color indicating different HP
+of the characters.

+
+.. note::
+
+   If a character shows up with color ``0``, it is safe to ignore it
+   since it is a dead body yet to be cleaned up.
+
+Flying bullets
+^^^^^^^^^^^^^^
+
+Bullets also export 4 properties like enemies:
+
+:Color:
+   The type and potential damage of the bullet (from 0.0 to 1.0),
+   encoded similarly to characters', except that aluminium bullets
+   only have 4 colors ``v``, ``w``, ``x`` and ``0``.
+:X-coordinate:
+   An integer within :math:`[0, 100 n_w]`.
+:Y-coordinate:
+   An integer within :math:`[0, 100 n_h]`.
+:Angle:

+Client Output Format
+--------------------
+
+Every loop, the server receives no more than 7 bytes in the format of
+``<Movement> <Angle> <Attack>``.  Again, these values need to be
+specially encoded.
+
+Movement
+^^^^^^^^
+
+This is the most awkward one.  As we can all imagine, there are nine different
+directions for the hero to move.  Were they represented as two-dimensional
+vectors, at least three characters would be needed to describe such
+a simple thing, e.g. ``1 0`` for :math:`m = (1, 0)`, and in the worst-case
+scenario :math:`m = (-1, -1)`, we would need five: ``-1 -1``.  40 bits are used
+to carry a four-bit piece of data, freaking insane, right?  So instead,
+we decided to *slightly* encode it like this:
+
+=========  ====  ===  =====
+Direction  Left  Nil  Right
+=========  ====  ===  =====
+**Up**        0    1      2
+**Nil**       3    4      5
+**Down**      6    7      8
+=========  ====  ===  =====
+
+Angle
+^^^^^
+
+Direction to point to hero to, might be useful to aim or to perform
+a close-range attack manually.  This value should also be converted
+to degrees and casted to a nonnegative integer.
+
+Attack
+^^^^^^
+
+Attack can be either of the three values:
+
+0. Do nothing
+1. Long-range attack
+2. Close-range attack
+
+Simple, huh?  Though be aware that this won't have any effect if the hero
+can yet strike an attack (as described in above section about `The Hero`_).
+
+Pseudo-Client
+-------------
+
+#. Create an INET, STREAMing socket ``sock``
+#. Connect ``sock`` to the address ``host:port`` which the server is bound to
+#. Receive length :math:`l` of data
+#. If :math:`l > 0`, close ``sock`` and quit
+#. Receive the data
+#. Process the data
+#. Send instruction for the hero to the server and go back to step 3
+
+Your AI should try to not only reach the highest score possible, but also in
+the smallest amount of time.  For convenience purpose, the server will
+log these values to stdout.
+
+There are samples of client implementations in different languages in
+the client-examples_ directory (more are coming).
