+Contributor Covenant Code of Conduct
+
+Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+education, socio-economic status, nationality, personal appearance, race,
+religion, or sexual identity and orientation.
+
+Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+
+Examples of unacceptable behavior by participants include:
+
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others’ private information, such as a physical or electronic
+address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+professional setting
+
+
+Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at carpedm20@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project’s leadership.
+
+Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+Contributing to ``fbchat``
+==========================
+
+Thanks for reading this, all contributions are very much welcome!
+
+Please be aware that ``fbchat`` uses `Scemantic Versioning <https://semver.org/>`__ quite rigorously!
+That means that if you're submitting a breaking change, it will probably take a while before it gets considered.
+
+Development Environment
+-----------------------
+
+This project uses ``flit`` to configure development environments. You can install it using:
+
+.. code-block:: sh
+
+    $ pip install flit
+
+And now you can install ``fbchat`` as a symlink:
+
+.. code-block:: sh
+
+    $ git clone https://github.com/carpedm20/fbchat.git
+    $ cd fbchat
+    $ # *nix:
+    $ flit install --symlink
+    $ # Windows:
+    $ flit install --pth-file
+
+This will also install required development tools like ``black``, ``pytest`` and ``sphinx``.
+
+After that, you can ``import`` the module as normal.
+
+Checklist
+---------
+
+Once you're done with your work, please follow the steps below:
+
+- Run ``black .`` to format your code.
+- Run ``pytest`` to test your code.
+- Run ``make -C docs html``, and view the generated docs, to verify that the docs still work.
+- Run ``make -C docs spelling`` to check your spelling in docstrings.
+- Create a pull request, and point it to ``master`` `here <https://github.com/carpedm20/fbchat/pulls/new>`__.

+==========================================
 
-.. image:: https://img.shields.io/badge/license-BSD-blue.svg
-    :target: LICENSE.txt
-    :alt: License: BSD
+A powerful and efficient library to interact with
+`Facebook's Messenger <https://www.facebook.com/messages/>`__, using just your email and password.
 
-.. image:: https://img.shields.io/badge/python-2.7%2C%203.4%2C%203.5%2C%203.6-blue.svg
-    :target: https://pypi.python.org/pypi/fbchat
-    :alt: Supported python versions: 2.7, 3.4, 3.5 and 3.6
+This is *not* an official API, Facebook has that `over here <https://developers.facebook.com/docs/messenger-platform>`__ for chat bots. This library differs by using a normal Facebook account instead.

+``fbchat`` currently support:
 
-Facebook Chat (`Messenger <https://www.facebook.com/messages/>`__) for Python.
-This project was inspired by `facebook-chat-api <https://github.com/Schmavery/facebook-chat-api>`__.
+- Sending many types of messages, with files, stickers, mentions, etc.
+- Fetching all messages, threads and images in threads.
+- Searching for messages and threads.
+- Creating groups, setting the group emoji, changing nicknames, creating polls, etc.
+- Listening for, an reacting to messages and other events in real-time.
+- Type hints, and it has a modern codebase (e.g. only Python 3.5 and upwards).
 
-**No XMPP or API key is needed**. Just use your email and password.
+Essentially, everything you need to make an amazing Facebook bot!
 
-Go to `Read the Docs <https://fbchat.readthedocs.io>`__ to see the full documentation,
-or jump right into the code by viewing the `examples <examples>`__
 
-Installation:
+Version Warning
+---------------
+``v2`` is currently being developed at the ``master`` branch and it's highly unstable.
 
-.. code-block:: console
 
-    $ pip install fbchat
+Caveats
+-------
 
-© Copyright 2015 - 2017 by Taehoon Kim / `@carpedm20 <http://carpedm20.github.io/about/>`__
+``fbchat`` works by imitating what the browser does, and thereby tricking Facebook into thinking it's accessing the website normally.
+
+However, there's a catch! **Using this library may not comply with Facebook's Terms Of Service!**, so be responsible Facebook citizens! We are not responsible if your account gets banned!
+
+Additionally, **the APIs the library is calling is undocumented!** In theory, this means that your code could break tomorrow, without the slightest warning!
+
+
+Installation
+------------
+
+.. code-block::
+
+    $ pip install git+https://git.karaolidis.com/karaolidis/fbchat.git

-FAQ
-===
-
-Version X broke my installation
--------------------------------
-
-We try to provide backwards compatability where possible, but since we're not part of Facebook,
-most of the things may be broken at any point in time
-
-Downgrade to an earlier version of fbchat, run this command
-
-.. code-block:: sh
-
-    $ pip install fbchat==<X>
-
-Where you replace ``<X>`` with the version you want to use
-
-
-Will you be supporting creating posts/events/pages and so on?
--------------------------------------------------------------
-
-We won't be focusing on anything else than chat-related things. This API is called `fbCHAT`, after all ;)
-
-
-Submitting Issues
------------------
-
-If you're having trouble with some of the snippets, or you think some of the functionality is broken,
-please feel free to submit an issue on `Github <https://github.com/carpedm20/fbchat>`_.
-You should first login with ``logging_level`` set to ``logging.DEBUG``::
-
-    from fbchat import Client
-    import logging
-    client = Client('<email>', '<password>', logging_level=logging.DEBUG)
-
-Then you can submit the relevant parts of this log, and detailed steps on how to reproduce
-
-.. warning::
-    Always remove your credentials from any debug information you may provide us.

-This project was inspired by `facebook-chat-api <https://github.com/Schmavery/facebook-chat-api>`_.
-
-**No XMPP or API key is needed**. Just use your email and password.
-
-Currently `fbchat` support Python 2.7, 3.4, 3.5 and 3.6:
-
-`fbchat` works by emulating the browser.
-This means doing the exact same GET/POST requests and tricking Facebook into thinking it's accessing the website normally.
-Therefore, this API requires the credentials of a Facebook account.
-
-.. note::
-    If you're having problems, please check the :ref:`faq`, before asking questions on Github
-
-.. warning::
-    We are not responsible if your account gets banned for spammy activities,
-    such as sending lots of messages to people you don't know, sending messages very quickly,
-    sending spammy looking URLs, logging in and out very quickly... Be responsible Facebook citizens.
-
-.. note::
-    Facebook now has an `official API <https://developers.facebook.com/docs/messenger-platform>`_ for chat bots,
-    so if you're familiar with node.js, this might be what you're looking for.
-
-If you're already familiar with the basics of how Facebook works internally, go to :ref:`examples` to see example usage of `fbchat`

-.. module:: fbchat
-.. _intro:
-
-Introduction
-============
-
-`fbchat` uses your email and password to communicate with the Facebook server.
-That means that you should always store your password in a seperate file, in case e.g. someone looks over your shoulder while you're writing code.
-You should also make sure that the file's access control is appropriately restrictive
-
-
-.. _intro_logging_in:
-
-Logging In
-----------
-
-Simply create an instance of :class:`Client`. If you have two factor authentication enabled, type the code in the terminal prompt
-(If you want to supply the code in another fasion, overwrite :func:`Client.on2FACode`)::
-
-    from fbchat import Client
-    from fbchat.models import *
-    client = Client('<email>', '<password>')
-
-Replace ``<email>`` and ``<password>`` with your email and password respectively
-
-.. note::
-    For ease of use then most of the code snippets in this document will assume you've already completed the login process
-    Though the second line, ``from fbchat.models import *``, is not strictly neccesary here, later code snippets will assume you've done this
-
-If you want to change how verbose `fbchat` is, change the logging level (in :class:`Client`)
-
-Throughout your code, if you want to check whether you are still logged in, use :func:`Client.isLoggedIn`.
-An example would be to login again if you've been logged out, using :func:`Client.login`::
-
-    if not client.isLoggedIn():
-        client.login('<email>', '<password>')
-
-When you're done using the client, and want to securely logout, use :func:`Client.logout`::
-
-    client.logout()
-
-
-.. _intro_threads:
-
-Threads
--------
-
-A thread can refer to two things: A Messenger group chat or a single Facebook user
-
-:class:`models.ThreadType` is an enumerator with two values: ``USER`` and ``GROUP``.
-These will specify whether the thread is a single user chat or a group chat.
-This is required for many of `fbchat`'s functions, since Facebook differetiates between these two internally
-
-Searching for group chats and finding their ID can be done via. :func:`Client.searchForGroups`,
-and searching for users is possible via. :func:`Client.searchForUsers`. See :ref:`intro_fetching`
-
-You can get your own user ID by using :any:`Client.uid`
-
-Getting the ID of a group chat is fairly trivial otherwise, since you only need to navigate to `<https://www.facebook.com/messages/>`_,
-click on the group you want to find the ID of, and then read the id from the address bar.
-The URL will look something like this: ``https://www.facebook.com/messages/t/1234567890``, where ``1234567890`` would be the ID of the group.
-An image to illustrate this is shown below:
-
-.. image:: /_static/find-group-id.png
-    :alt: An image illustrating how to find the ID of a group
-
-The same method can be applied to some user accounts, though if they've set a custom URL, then you'll just see that URL instead
-
-Here's an snippet showing the usage of thread IDs and thread types, where ``<user id>`` and ``<group id>``
-corresponds to the ID of a single user, and the ID of a group respectively::
-
-    client.sendMessage('<message>', thread_id='<user id>', thread_type=ThreadType.USER)
-    client.sendMessage('<message>', thread_id='<group id>', thread_type=ThreadType.GROUP)
-
-Some functions (e.g. :func:`Client.changeThreadColor`) don't require a thread type, so in these cases you just provide the thread ID::
-
-    client.changeThreadColor(ThreadColor.BILOBA_FLOWER, thread_id='<user id>')
-    client.changeThreadColor(ThreadColor.MESSENGER_BLUE, thread_id='<group id>')
-
-
-.. _intro_message_ids:
-
-Message IDs
------------
-
-Every message you send on Facebook has a unique ID, and every action you do in a thread,
-like changing a nickname or adding a person, has a unique ID too.
-
-Some of `fbchat`'s functions require these ID's, like :func:`Client.reactToMessage`,
-and some of then provide this ID, like :func:`Client.sendMessage`.
-This snippet shows how to send a message, and then use the returned ID to react to that message with a 😍 emoji::
-
-    message_id = client.sendMessage('message', thread_id=thread_id, thread_type=thread_type)
-    client.reactToMessage(message_id, MessageReaction.LOVE)
-
-
-.. _intro_interacting:
-
-Interacting with Threads
-------------------------
-
-`fbchat` provides multiple functions for interacting with threads
-
-Most functionality works on all threads, though some things,
-like adding users to and removing users from a group chat, logically only works on group chats
-
-The simplest way of using `fbchat` is to send a message.
-The following snippet will, as you've probably already figured out, send the message `test message` to your account::
-
-    message_id = client.sendMessage('test message', thread_id=client.uid, thread_type=ThreadType.USER)
-
-You can see a full example showing all the possible thread interactions with `fbchat` by going to :ref:`examples`
-
-
-.. _intro_fetching:
-
-Fetching Information
---------------------
-
-You can use `fbchat` to fetch basic information like user names, profile pictures, thread names and user IDs
-
-You can retrieve a user's ID with :func:`Client.searchForUsers`.
-The following snippet will search for users by their name, take the first (and most likely) user, and then get their user ID from the result::
-
-    users = client.searchForUsers('<name of user>')
-    user = users[0]
-    print("User's ID: {}".format(user.uid))
-    print("User's name: {}".format(user.name))
-    print("User's profile picture url: {}".format(user.photo))
-    print("User's main url: {}".format(user.url))
-
-Since this uses Facebook's search functions, you don't have to specify the whole name, first names will usually be enough
-
-You can see a full example showing all the possible ways to fetch information with `fbchat` by going to :ref:`examples`
-
-
-.. _intro_sessions:
-
-Sessions
---------
-
-`fbchat` provides functions to retrieve and set the session cookies.
-This will enable you to store the session cookies in a seperate file, so that you don't have to login each time you start your script.
-Use :func:`Client.getSession` to retrieve the cookies::
-
-    session_cookies = client.getSession()
-
-Then you can use :func:`Client.setSession`::
-
-    client.setSession(session_cookies)
-
-Or you can set the ``session_cookies`` on your initial login.
-(If the session cookies are invalid, your email and password will be used to login instead)::
-
-    client = Client('<email>', '<password>', session_cookies=session_cookies)
-
-.. warning::
-    You session cookies can be just as valueable as you password, so store them with equal care
-
-
-.. _intro_events:
-
-Listening & Events
-------------------
-
-To use the listening functions `fbchat` offers (like :func:`Client.listen`),
-you have to define what should be executed when certain events happen.
-By default, (most) events will just be a `logging.info` statement,
-meaning it will simply print information to the console when an event happens
-
-.. note::
-    You can identify the event methods by their `on` prefix, e.g. `onMessage`
-
-The event actions can be changed by subclassing the :class:`Client`, and then overwriting the event methods::
-
-    class CustomClient(Client):
-        def onMessage(self, mid, author_id, message, thread_id, thread_type, ts, metadata, msg, **kwargs):
-            # Do something with the message here
-            pass
-
-    client = CustomClient('<email>', '<password>')
-
-**Notice:** The following snippet is as equally valid as the previous one::
-
-    class CustomClient(Client):
-        def onMessage(self, message, author_id, thread_id, thread_type, **kwargs):
-            # Do something with the message here
-            pass
-
-    client = CustomClient('<email>', '<password>')
-
-The change was in the parameters that our `onMessage` method took: ``message`` and ``author_id`` got swapped,
-and ``mid``, ``ts``, ``metadata`` and ``msg`` got removed, but the function still works, since we included ``**kwargs``
-
-.. note::
-    Therefore, for both backwards and forwards compatability,
-    the API actually requires that you include ``**kwargs`` as your final argument.
-
-View the :ref:`examples` to see some more examples illustrating the event system
