+=============================
+Nim bindings for Godot Engine
+=============================
+
+:Author: Ruslan Mustakov
+:Version: |godotnimversion|
+:GitHub: `$GODOTNIM_GITHUB_URL <$GODOTNIM_GITHUB_URL>`_
+:License: MIT
+
+.. contents::
+
+``godot-nim`` library allows to create games on
+`Godot Engine <https://godotengine.org/>`_ with
+`Nim programming language <https://nim-lang.org/>`_. Nim is a statically typed
+language with an elegant Python-like syntax that compiles to native code.
+It is garbage-collected, but its GC supports real-time mode which this library
+makes use of. It means the GC will never run during game frames and will use
+fixed amount of frame idle time to collect garbage. This leads to no stalls
+and close to zero compromise on performance comparing to native languages with
+manual memory management.
+
+If you are not familiar with Nim yet, it is recommended to go through the
+`official tutorial <https://nim-lang.org/docs/tut1.html>`_.
+
+`VSCode <https://code.visualstudio.com/>`_ is the recommended editor for
+working with Nim code. It is cross-platform and has the excellent
+`nim plugin <https://marketplace.visualstudio.com/items?itemName=kosz78.nim>`_
+that supports most of the features you would expect from an IDE.
+It also has `godot-tools plugin <https://marketplace.visualstudio.com/items?itemName=geequlim.godot-tools>`_
+which adds features for editing GDScript and Godot resource files.
+
+
+Getting Started
+===============
+
+Getting Godot
+--------------
+
+The library requires Godot version 3.0, which you can get here:
+https://godotengine.org/download
+
+Installing Nim
+-------------
+
+The library requires Nim version 0.18.0 or newer, which you can get here:
+https://nim-lang.org/install.html
+
+Make sure you also have ``nimble`` (Nim's package manager) installed.
+
+Creating Project
+----------------
+
+The fastest way to set up a Godot-Nim project is to use the existing stub:
+
+.. code-block:: bash
+   git clone --depth=1 https://github.com/pragmagic/godot-nim-stub.git myproject
+
+(you can then delete the .git directory within to untie the project from the
+stub repository)
+
+The stub contains the necessary build configuration to compile your code for
+desktop and mobile platforms, as well as a couple of very simple scenes to
+help you get started. Consult the stub's `README
+<https://github.com/pragmagic/godot-nim-stub>`_ for information about
+compiling the project.
+
+
+Adding Nim to Existing Project
+------------------------------
+
+If you would like to use Nim in an existing project:
+
+1. Copy ``nakefile.nim`` file and ``src`` directory from the stub described
+   in the previous section above your Godot project folder. Adjust paths in
+   build scripts (``nakefile.nim``, ``src/stub.nimble``) according to your
+   own project structure.
+
+2. Copy ``nimlib.gdnlib`` to your Godot project folder. It is a
+   GDNative library resource that contains paths to dynamic libraries
+   compiled by Nim.
+
+Next Steps
+----------
+
+Once you are familiarized with the build process (it's as simple as running
+``nake build`` after you are set up), it is recommended to go through
+`godotmacros <godotmacros.html>`_ and `godotnim <godotnim.html>`_ module
+documentations. They describe special macros and procedures needed to define
+or instantiate Godot objects. After you learned that, the rest is similar to
+using any Nim library. These bindings do not limit any of Nim's capabilities,
+and you can use any Nim types as fields or parameters of Godot objects and
+their procedures (but, obviously, you may not be able to export some of them
+to Godot editor or GDScript, unless you define your own converters).
+
+
+Modules
+=======
+
+The binding library consists of three major modules:
+
+* `godot <#modules-godot-module>`_ - Contains core types and macro definitions.
+  You need to import this in any module that defines or makes use of Godot
+  types.
+
+* `godotinternal <#modules-godotinternal-module>`_ - Contains raw wrappers over
+  few core types, such as ``GodotVariant``, ``GodotString``, ``GodotNodePath``,
+  ``GodotDictionary``, pool arrays. These are used by ``godotapigen`` and macro
+  implementations, and you don't have to use them at all in your code, unless
+  you want to go into low-level details for some reason. Each of those types
+  needs to be destructed manually with ``deinit`` procedure.
+
+* `godotapigen <godotapigen.html>`_ - Wrapper generator based on data from
+  Godot's ``ClassDB``. You only need to use it as a part of the build process.
+
+
+godot Module
+------------
+
+Contains core types and macro definitions. You need to import this in any
+module that defines or makes use of Godot types. The sumbodules below are
+exported and you don't have to import any of them directly.
+
+* `godotnim <godotnim.html>`_ Defines ``NimGodotObject`` and Varaint converters
+  for standard Nim types.
+* `godotmacros <godotmacros.html>`_ Defines ``gdobj`` macro for defining
+  Godot objects.
+* `variants <variants.html>`_ ``Variant`` type represents a "dynamic object"
+  that many Godot procedures make use of.
+* `arrays <arrays.html>`_ Defines ``Array`` of Variants.
+* `basis <basis.html>`_ Defines 3D ``Basis``.
+* `colors <colors.html>`_ Defines ARGB ``Color``.
+* `dictionaries <dictionaries.html>`_ Defines ``Variant`` -> ``Variant``
+  ``Dictionary``.
+* `nodepaths <nodepaths.html>`_ Defines ``NodePath`` - a path to a ``Node``.
+* `planes <planes.html>`_ Defines 3D ``Plane``.
+* `poolarrays <poolarrays.html>`_ Defines pooled arrays: ``PoolByteArray``,
+  ``PoolIntArray``, ``PoolRealArray``, ``PoolVector2Array``,
+  ``PoolVector3Array``, ``PoolColorArray``, ``PoolStringArray``.
+* `quats <quats.html>`_ Defines ``Quat`` (quaternion) describing object
+  rotation in 3D space.
+* `rect2 <rect2.html>`_ Defines ``Rect2`` - a 2D rectangle.
+* `aabb <aabb.html>`_ Defines ``AABB`` - a 3D box.
+* `rids <rids.html>`_ Defines ``RID`` - a resource identifier.
+* `transform2d <transform2d.html>`_ Defines ``Transform2D``.
+* `transforms <transforms.html>`_ Defines ``Transform``.
+* `vector2 <vector2.html>`_ Defines ``Vector2``.
+* `vector3 <vector3.html>`_ Defines ``Vector3``.
+* `godotbase <godotbase.html>`_ Defines ``Error`` type and few common math
+  procedures missing in Nim's standard library.

+
+This is an auto-generated list of Godot API modules. It's built from Godot
+changeset `$GODOTAPI_CHANGESET_HASH

+
+$AUTO_GENERATED_GODOTAPI_LIST
+
+
+godotinternal Module
+--------------------
+
+Contains low-level wrappers over Godot types that require manual memory
+management. This module is used within ``godot-nim`` implementation and you
+don't need to import it unless you know what you are doing.
+
+* `godotdictionaries <godotdictionaries.html>`_
+* `godotnodepaths <godotnodepaths.html>`_
+* `godotpoolarrays <godotpoolarrays.html>`_
+* `godotstrings <godotstrings.html>`_
+* `godotvariants <godotvariants.html>`_
