+ev3dev language bindings
+========================
+
+This repository stores the utilities and metadata information for the
+ev3dev-lang family of libraries. These libraries are easy-to-use interfaces for
+the APIs that are available on `ev3dev`_-based devices.
+
+The complete documentation is hosted at http://ev3dev-lang.readthedocs.org.
+
+We support multiple libraries for various programming languages using a
+centralized "specification" which we keep updated as kernel changes are made.
+We don't have the actual library code here (see below) -- instead we use this
+repo to facilitate the maintenance of our bindings.
+
+We currently support libraries for the following languages:
+
+- `C++`_
+- `Node.js`_
+- `Python`_
+
+Each binding is written based on our central spec, so each has a uniform
+interface which is kept close to the ev3dev API surface while still encouraging
+language-specific enhancements.

+Autogen scripts for ev3dev language bindings
+============================================
+
+To help us maintain our language bindings, we have written a script to
+automatically update sections of code according to changes in our API
+specification. We define code templates using Liquid_, which are stored in the
+``templates`` folder with the ``.liquid`` extension.
+
+.. _Liquid: http://liquidmarkup.org
+
+Usage
+-----
+
+Prerequisites
+#############
+
+- Make sure that you have cloned the repo (including submodules) and ``cd``'d
+  into the autogen directory
+- You must have Node.JS and ``npm`` installed
+- If you have not yet done so yet, run ``npm install`` to install the
+  dependencies for auto-generation
+
+Running from the command line
+#############################
+
+If you run the script without any parameters, it will look for an
+``autogen-config.json`` file in your current working directory. The
+autogen-config file specifies the locations to look for templates and source
+files.
+
+.. code-block:: bash
+
+    $ node path/to/autogen.js
+
+If you want to specify a config file manually, you can include use a full file
+path for the target JSON config file.
+
+.. code-block:: bash
+
+    $ node path/to/autogen.js other/path/to/config.json
+
+How it works
+------------
+
+Our script searches code files for comments that define blocks of code that it
+should automatically generate. The inline comment tags are formatted as follows
+(C-style comments):
+
+.. code-block:: cpp
+
+    //~autogen test-template foo.bar>tmp
+    ...
+    //~autogen
+
+After the initial declaration (``~autogen``), the rest of the comment defines
+parameters for the generation script. The first block of text up to the space
+is the file name of the template to use. The ``.liquid`` extension is
+automatically appended to the given name, and then the file is loaded and
+parsed.
+
+The rest of the comment is a space-separated list of contextual variables. The
+section before the ``>`` defines the source, and the section after defines the
+destination. The value from the source is copied to the destination, in the
+global Liquid context. This makes it possible to use a single template file to
+generate multiple classes.
+

+
+Contributing to the autogen script
+----------------------------------
+
+Just as we welcome contributions to the language bindings in this repo, we love
+to have people update our infrastructure. If you want to make a contribution,
+here are some quick tips to get started developing.
+
+- After making a change, you should run the script and tell it to re-generate
+  some files to make sure that your changes work as expected.
+- If you are making more extensive changes, it may be helpful to create a
+  temporary regen group with some test files to be able to manually test any
+  new features or modifications.
+- Although you can use any text editor, we recommend using
+  `Visual Studio Code`_ to edit the autogen scripts. It has great autocomplete,
+  and their debug GUI works well with node.
