+# 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
+Discord: Light7734#4652.
+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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
+
+Community Impact Guidelines were inspired by [Mozilla's code of conduct
+enforcement ladder](https://github.com/mozilla/diversity).

+# How to contribute to Light Engine
+
+Thanks for putting in the time to contribute to this project <3
+
+## Coding conventions
+
+For the time being, don't worry too much about the conventions...
+
+Try to read other parts of the code and you'll get the hang of it
+
+I have to learn clang-format, then everyone contributing can use it to format their code
+
+

-Development Strategy
+Development
 ===================================================================================================
-Defines:
+As a solo-project, I am not only the **developer**, but also the **manager**. 
+Therefore there is a need, if this project is to succeed, to have a development plan. 
 
-- A **unit of work**.
-- A **pipeline** for making changes ---should **minimize ambiguity**.
-- A way for **distributing work** and **tracking productivity**.
+Such a plan should:
 
-An **unpragmatic strategy** is utterly useless. It should pull our minds out from the **engineering dreamland**, and make us focus on the **product delivery**.
+- Define a way to **distribute work** (across time, since there's only 1 developer).
+- Define what is a **unit of work** (cycles).
+- Provide a way to **track productivity**, which helps projecting the future and **detecting patterns** early on.
+- Provide a **pipeline** for the work to go through and **minimize ambiguity**.
 
-.. note::
-   **Forgejo issues** is used as the project-management tool.
-   No need for fancy boards or 3rd party apps. Simple tags, titles, milestones, etc... should suffice.
+These are the **management** aspects of the project, which help the development goals to be more **pragmatic**
+---by pulling my mind out of its **engineering dreamland**, and make it focus on the **broader picture**.

+        - Make a ticket if stash-fix is implausible ---**DO NOT** write **todo** comments.
         - The message should follow the project's **commit message specifications**.
 
-    - Make an issue.

+        - Provide a very brief description ---This may be used in the commit message's body.
 
 2 - Make it work
     - Write high-level tests that confirms the cycle's requirements are met.
         - That is, specify requirements in a programming language instead of English.
         - You're done when all the tests pass.
         - Preferably write the tests first, but it's okay to start with the interface.
-        - Tests **may** not be necessary depending on the requirements and commit type.
