+# 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, sex characteristics, 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 j@gro.sh. 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.

 Please see the [Setup Page](https://github.com/jagrosh/MusicBot/wiki/Setup) in the wiki to run this bot yourself!
 
-# Questions/Suggestions/Bug Reports
-If you'd like to suggest changes to how the bot functions, recommend more customization options, or report bugs, feel free to either open an [Issue](https://github.com/jagrosh/MusicBot/issues) on this repository, or join [my Discord server](https://discord.gg/0p9LSGoRLu6Pet0k). If you like this bot, be sure to add a star to the libraries that make this possible: [**JDA**](https://github.com/DV8FromTheWorld/JDA) and [**lavaplayer**](https://github.com/sedmelluq/lavaplayer)
+## Questions/Suggestions/Bug Reports
+**Please read the [Suggested/Planned Features List](https://github.com/jagrosh/MusicBot/projects/1) before suggesting a feature**. If you'd like to suggest changes to how the bot functions, recommend more customization options, or report bugs, feel free to either open an [Issue](https://github.com/jagrosh/MusicBot/issues) on this repository, or join [my Discord server](https://discord.gg/0p9LSGoRLu6Pet0k). (Note: I will not accept any feature requests that will require additional API keys, nor any non-music features). If you like this bot, be sure to add a star to the libraries that make this possible: [**JDA**](https://github.com/DV8FromTheWorld/JDA) and [**lavaplayer**](https://github.com/sedmelluq/lavaplayer)

+## Editing
+This bot (and the source code here) might not be easy to edit for inexperienced programmers. The main purpose of having the source public is to show the capabilities of the libraries, to allow others to understand how the bot works, and to allow those knowledgeable about java, JDA, and Discord bot development to contribute. There are many requirements and dependencies required to edit and compile it, and there will not be support provided for people looking to make changes on their own. Instead, consider making a feature request (see the above section). If you choose to make edits, please do so in accordance with the Apache 2.0 License.
