 ## 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.
+We pledge to make our community welcoming, safe, and equitable for all.
 
-## Our Standards
+We are committed to fostering an environment that respects and promotes the dignity, rights, and contributions of all individuals, regardless of characteristics including race, ethnicity, caste, color, age, physical characteristics, neurodiversity, disability, sex or gender, gender identity or expression, sexual orientation, language, philosophy or religion, national or social origin, socio-economic position, level of education, or other status. The same privileges of participation are extended to everyone who participates in good faith and in accordance with this Covenant.
 
-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
+## Encouraged Behaviors
 
-Examples of unacceptable behavior by participants include:
+While acknowledging differences in social norms, we all strive to meet our community's expectations for positive behavior. We also understand that our words and actions may be interpreted differently than we intend based on culture, background, or native language.
 
-* 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
+With these considerations in mind, we agree to behave mindfully toward each other and act in ways that center our shared values, including:
 
-## Our Responsibilities
+1. Respecting the **purpose of our community**, our activities, and our ways of gathering.
+2. Engaging **kindly and honestly** with others.
+3. Respecting **different viewpoints** and experiences.
+4. **Taking responsibility** for our actions and contributions.
+5. Gracefully giving and accepting **constructive feedback**.
+6. Committing to **repairing harm** when it occurs.
+7. Behaving in other ways that promote and sustain the **well-being of our community**.
 
-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.
+## Restricted Behaviors
 
-## Scope
+We agree to restrict the following behaviors in our community. Instances, threats, and promotion of these behaviors are violations of this Code of Conduct.
 
-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.
+1. **Harassment.** Violating explicitly expressed boundaries or engaging in unnecessary personal attention after any clear request to stop.
+2. **Character attacks.** Making insulting, demeaning, or pejorative comments directed at a community member or group of people.
+3. **Stereotyping or discrimination.** Characterizing anyone’s personality or behavior on the basis of immutable identities or traits.
+4. **Sexualization.** Behaving in a way that would generally be considered inappropriately intimate in the context or purpose of the community.
+5. **Violating confidentiality**. Sharing or acting on someone's personal or private information without their permission.
+6. **Endangerment.** Causing, encouraging, or threatening violence or other harm toward any person or group.
+7. Behaving in other ways that **threaten the well-being** of our community.
 
-## Enforcement
+### Other Restrictions
 
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at vexorian@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.
+1. **Misleading identity.** Impersonating someone else for any reason, or pretending to be someone else to evade enforcement actions.
+2. **Failing to credit sources.** Not properly crediting the sources of content you contribute.
+3. **Promotional materials**. Sharing marketing or other commercial content in a way that is outside the norms of the community.
+4. **Irresponsible communication.** Failing to responsibly present content which includes, links or describes any other restricted behaviors.
 
-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.
+## 'AI' policy
+
+There are ways in which a LLM-based tool can be helpful such as when searching the web or for learning. More so, tools like github and google themselves are being modified to railroad users into using LLM-based tools. It'd be really impractical and neigh-impossible to ban 'AI' altogether from being used during the development of a contribution and that's not really the purpose of this policy.
+
+HOWEVER, from a legal standpoint, it is too difficult to know the origin of LLM-generated code so there are risks of it infringing on copyright. And from a pragmatic stand point, we want to be able to trust the quality of the code. That is to say, we do not want contributions where the bulk of the code was AI-generated or or where the contributors themselves do not understand the code being pushed. This is also in relation to items 4 and 5 of the encouraged behaviors. We want contributors that can vouch for the code they contribute and can receive and act on constructive feedback to it.
+
+Note that this is only a policy affecting Pull Requests to this project. This project is released under a permissive FOSS licence, so there's nothing really that can stop forks from having a different policy on this and any individual is allowed to create such a fork should they want to.
+
+## Reporting an Issue
+
+Tensions can occur between community members even when they are trying their best to collaborate. Not every conflict represents a code of conduct violation, and this Code of Conduct reinforces encouraged behaviors and norms that can help avoid conflicts and minimize harm.
+
+When an incident does occur, it is important to report it promptly. To report a possible violation, may be
+reported by contacting the project team at vexorian@gmail.com

 ## Limitations
 
@@ -32,6 +33,7 @@ EPG (Guide Information) data is stored to `.dizquetv/xmltv.xml`
 - dizqueTV does not currently watch your Plex server for media updates/changes. You must manually remove and re-add your programs for any changes to take effect. Same goes for Plex server changes (changing IP, port, etc).. You'll have to update the server settings manually in that case.
 - Most players (including Plex) will break after switching episodes if video / audio format is too different. dizqueTV can  be configured to use ffmpeg transcoding to prevent this, but that costs resources.
 - If you configure Plex DVR, it will always be recording and transcoding the channel's contents.
+- In its current state, dizquetv is intended for private use only and you should be discouraged from running dizqueTV in any capacity where other users can have access to dizqueTV's ports. You can use Plex's iptv player feature to share dizqueTV streams or you'll have to come up with some work arounds to make sure that streams can be played without ever actually exposing the dizquetv port to the outside world. Please use it with care, consider exposing dizqueTV's ports as something only advanced users who know what they are doing should try.
