+Manim Installation For Developers
+=================================
+
+	This documentation is for developers who want to contribute to ``ManimCommunity/manim``.
+
+Installing Poetry
+*****************
+
+Poetry can be easily installed in any OS by just running the below command.
+
+If your system has the ``curl`` program installed, which is usually true in Linux and Mac,
+
+.. code-block:: bash
+
+	  curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
+
+
+If you are a Windows developer and want to use PowerShell, you can use the below command.
+
+.. code-block:: bash
+
+	  (Invoke-WebRequest -Uri https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py -UseBasicParsing).Content | python
+
+.. note:: Poetry can be installed by other ways also, such as with ``pip``. See `<https://python-poetry.org/docs/#alternative-installation-methods-not-recommended>`_.
+
+It will add it to ``PATH`` variable automatically. In order to make sure you have poetry installed correctly, try running:
+
+.. code-block:: bash
+
+	poetry --version
+
+
+.. note:: You may need to restart your shell in order for the changes to take effect.
+
+See the `docs on installation python poetry for more information
+<https://python-poetry.org/docs/>`_.
+
+Installing System Dependencies
+******************************
+
+Please follow the instructions under :ref:`installing-manim` to install all dependencies. Then come back to this page to continue with the installation.
+
+.. important:: Windows Users can skip the steps to install Pycairo.
+
+
+Additionally, ``git`` has to be installed. For instructions see `Documentation
+<https://git-scm.com/>`_.
+
+.. _install-manim-poetry:
+
+Installing Manim using Poetry
+*****************************
+
+1.  First, clone the Manim repo locally using git.
+
+    .. code-block:: bash
+
+		git clone https://github.com/ManimCommunity/manim.git
+
+    or
+
+    .. code-block:: bash
+
+		git clone git@github.com:ManimCommunity/manim.git
+
+2.  Open a Terminal/Powershell/Command Prompt and cd into the cloned directory.
+
+    .. code-block:: bash
+
+		cd path/to/manim
+
+
+    .. note:: This path should contain a file called ``pyproject.toml`` if it doesn't contain it, you would need to go a level up.
+
+3.  Use the below command to install python dependencies. This will use the default python version installed.
+
+    .. code-block:: bash
+
+         poetry install
+
+
+    .. note:: Poetry will create a virtual environment rooted at the current directory.
+
+    You can select the desired python version using 
+
+    .. code-block:: bash
+
+         poetry env use <python version you need>
+
+    For example you can use for python 3.7.
+
+    .. code-block:: bash
+
+         poetry env use 3.7
+
+    For more information about this you can visit the `docs
+    <https://python-poetry.org/docs/managing-environments/>`_.
+
+4.  Now you can activate the virtual environment ``Poetry`` has created by using the command below.
+
+    .. code-block:: bash
+
+       poetry shell
+
+    Or if you want to run a single command use
+
+    .. code-block:: bash
+
+       poetry run manim -h
+
+Now you are free to start developing on the Manim Repository.
+
+Running the Tests Using Poetry
+******************************
+
+Once you are done with :ref:`install-manim-poetry`, you can run manim's test suite by activating a shell using ``poetry shell`` command and then running the command ``pytest`` to run the tests. 
+
+.. code-block:: bash
+
+   poetry shell
+   pytest
+
+.. important:: You should always run the test suite before making a PR. For other contributing guidelines, see `the guide for contributions to manim <../contributing.html>`_.
+
+
+Code Formatting Using Poetry
+****************************
+
+Once you are done with :ref:`install-manim-poetry`, you can run the code formatter ``black`` by activating a shell using ``poetry shell`` and then running the command ``black manim``. Or alternatively just use the command ``poetry run black manim``. 
+
+.. code-block:: bash
+
+   poetry shell
+   black
+
+.. note:: Here, the word ``manim``, as used in the commands ``black manim`` or ``poetry run black manim``, refers to the folder which ``black`` is to format. You can also reformat the files containing the test suite by running the command ``black tests``.
+
+For example, if you have written some new example and want to format it use the below command
+
+.. code-block:: bash
+
+    poetry run black example_scenes
+
