 Our projects are open-source and are automatically deployed whenever commits are pushed to the `master` branch on each repository, so we've created a set of guidelines in order to keep everything clean and in working order.
 
+Note that contributions may be rejected on the basis of a contributor failing to follow these guidelines.

 ## Rules
 
 1. You must be a member of [our Discord community](https://discord.gg/python) in order to contribute to this project.
-2. Your pull request must solve an issue created by or approved a staff member or event handler. These will be labeled with the `approved` label. Feel free to suggest issues of your own, which staff can choose to approve.

 3. **No force-pushes** or modifying the Git history in any way.
 4. If you have direct access to the repository, **create a branch for your changes** and create a pull request for that branch. If not, create a branch on a fork of the repository and create a pull request from there.
     * It's common practice for a repository to reject direct pushes to `master`, so make branching a habit!

 7. **Avoid frequent pushes to the main repository**. This goes for PRs opened against your fork as well. Our test build pipelines are triggered every time a push to the repository (or PR) is made. Try to batch your commits until you've finished working for that session, or you've reached a point where collaborators need your commits to continue their own work. This also provides you the opportunity to amend commits for minor changes rather than having to commit them on their own because you've already pushed.
     * This includes merging master into your branch. Try to leave merging from master for after your PR passes review; a maintainer will bring your PR up to date before merging. Exceptions to this include: resolving merge conflicts, needing something that was pushed to master for your branch, or something was pushed to master that could potentionally affect the functionality of what you're writing.
 8. **Don't fight the framework**. Every framework has its flaws, but the frameworks we've picked out have been carefully chosen for their particular merits. If you can avoid it, please resist reimplementing swathes of framework logic - the work has already been done for you!
-9. If someone is working on a pull request, **do not open your own pull request for the same task**. Instead, collaborate with the author(s) of the existing pull request. Communication is key, and there's no point in two separate implementations of the same thing.
+9. If someone is working on an issue or pull request, **do not open your own pull request for the same task**. Instead, collaborate with the author(s) of the existing pull request. Duplicate PRs opened without communicating with the other author(s) and/or PyDis staff will be closed. Communication is key, and there's no point in two separate implementations of the same thing.
     * One option is to fork the other contributor's repository and submit your changes to their branch with your own pull request. We suggest following these guidelines when interacting with their repository as well.

 11. **Internal projects are internal**. As a contributor, you have access to information that the rest of the server does not. With this trust comes responsibility - do not release any information you have learned as a result of your contributor position. We are very strict about announcing things at specific times, and many staff members will not appreciate a disruption of the announcement schedule.
+12. All static content, such as images or audio, **must be licensed for open public use**.
+    * Static content must be hosted by a service designed to do so. Failing to do so is known as "leeching" and is frowned upon, as it generates extra bandwidth costs to the host without providing benefit. It would be best if appropriately licensed content is added to the repository itself so it can be served by PyDis' infrastructure.
 
 Above all, the needs of our community should come before the wants of an individual. Work together, build solutions to problems and try to do so in a way that people can learn from easily. Abuse of our trust may result in the loss of your Contributor role, especially in relation to Rule 7.

For users unfamiliar with the Pipenv workflow, Pipenv's documentation provides a [Basic Usage](https://pipenv.readthedocs.io/en/latest/basics/) tutorial, along with some of the more advanced workflows. A project-specific installation guide can be found in [Seasonalbot's README](https://github.com/python-discord/seasonalbot/blob/master/README.md).
+
+When pulling down changes from GitHub, remember to sync your environment using `pipenv sync --dev` to ensure you're using the most up-to-date versions the project's dependencies.
+
+### Type Hinting
+[PEP 484](https://www.python.org/dev/peps/pep-0484/) formally specifies type hints for Python functions, added to the Python Standard Library in version 3.5. Type hints are recognized by most modern code editing tools and provide useful insight into both the input and output types of a function, preventing the user from having to go through the codebase to determine these types. 
+
+For example:
+
+```py
+def foo(input_1: int, input_2: dict) -> bool:
+```
+
+Tells us that `foo` accepts an `int` and a `dict` and returns a `bool`.
+
+All function declarations should be type hinted in code contributed to the PyDis organization.
+
+For more information, see *[PEP 483](https://www.python.org/dev/peps/pep-0483/) - The Theory of Type Hints* and Python's documentation for the [`typing`](https://docs.python.org/3/library/typing.html) module.
+
+### AutoDoc Formatting Directives
+Many documentation packages provide support for automatic documentation generation from the codebase's docstrings. These tools utilize special formatting directives to enable richer formatting in the generated documentation.
+
+For example:
+
+```py
+def foo(bar: int, baz: dict=None) -> bool:
+    """
+    Does some things with some stuff.
+
+    :param bar: Some input
+    :param baz: Optional, some other input
+
+    :return: Some boolean
+    """
+```
+
+Since PyDis does not utilize automatic documentation generation, use of this syntax should not be used in code contributed to the organization. Should the purpose and type of the input variables not be easily discernable from the variable name and type annotation, a prose explanation can be used. Explicit references to variables, functions, classes, etc. should be wrapped with backticks (`` ` ``).
+
+For example, the above docstring would become:
+
+```py
+def foo(bar: int, baz: dict=None) -> bool:
+    """
+    Does some things with some stuff.
+
+    This function takes an index, `bar` and checks for its presence in the database `baz`, passed as a dictionary.
+
+    Returns `False` if `baz` is not passed.
+    """
+```

+Github [has introduced a new PR feature](https://github.blog/2019-02-14-introducing-draft-pull-requests/) that allows the PR author to mark it as a WIP. This provides both a visual and functional indicator that the contents of the PR are in a draft state and not yet ready for formal review.
