+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible 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 act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders 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, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+contact@piplabs.xyz.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+# Contributing to Story
+Thank you for considering making contributions to Story and related repositories! Below you can find what's the best way that you can help.
+
+## Coding Guideline
+
+[Go coding guidelines](https://go.dev/wiki/CodeReviewComments)
+
+[Good commit messages](https://chris.beams.io/posts/git-commit/)
+
+## Bug Reports
+
+* Ensure your issue [has not already been reported][1]. It may already be fixed!
+* Include the steps you carried out to produce the problem.
+* Include the behavior you observed along with the behavior you expected, and
+  why you expected it.
+* Include any relevant stack traces or debugging output.
+
+## Feature Requests
+
+We welcome feedback with or without pull requests. If you have an idea for how
+to improve the project, great! All we ask is that you take the time to write a
+clear and concise explanation of what need you are trying to solve. If you have
+thoughts on _how_ it can be solved, include those too!
+
+The best way to see a feature added, however, is to submit a pull request.
+
+## Pull Requests
+
+* Before creating your pull request, it's usually worth asking if the code
+  you're planning on writing will actually be considered for merging. You can
+  do this by [opening an issue][1] and asking. It may also help give the
+  maintainers context for when the time comes to review your code.
+
+* Ensure your [commit messages are well-written][2]. This can double as your
+  pull request message, so it pays to take the time to write a clear message.
+
+* Add tests for your feature. You should be able to look at other tests for
+  examples. If you're unsure, don't hesitate to [open an issue][1] and ask!
+
+* Submit your pull request!
+    - Fork the repository on GitHub.
+    - Make your changes on your fork repository.
+    - Submit a PR.
+
+* Each PR needs to link to a github issue. Please open a github issue first to describe the code changes you plan to make and the problem it solves. Then link the issue in your PR.
+
+* PR title and body follows [conventional commit][3].
+   - Title template: `type(app/pkg): concise description`
+   - See [allowed types][4]
+   - Description must be concise: lower case, no punctuation, no more than 50 characters.
+   - Scope must be concise: only a one or two folders; e.g. 'client/cmd' or 'github' or '*'
+
+## Find something to work on
+
+We are always in need of help, be it fixing documentation, reporting bugs or writing some code.
+Look at places where you feel best coding practices aren't followed, code refactoring is needed or tests are missing.
+
+If you have questions about the development process,
+feel free to [file an issue](https://github.com/piplabs/story-staking-api/issues/new).
+
+## Code Review
+
+To make it easier for your PR to receive reviews, consider the reviewers will need you to:
+
+* follow [good coding guidelines](https://go.dev/wiki/CodeReviewComments).
+* write [good commit messages](https://chris.beams.io/posts/git-commit/).
+* break large changes into a logical series of smaller patches which individually make easily understandable changes, and in aggregate solve a broader issue.
