CODE_OF_CONDUCT.rst

+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
+foss@teckids.org. 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 project community.

CONTRIBUTING.rst

+Development principles and contribution guidelines
+==================================================
+
+In order to create a high-quality software product, the BiscuIT developers
+have agreed upon fundamental principles governing the code layout, coding
+style and repository management for BiscuIT and all official apps.
+
+
+Coding layout and style
+-----------------------
+
+The coding style is defined in `PEP 8`_, with the following differences and
+decisions:
+
+- The maximum line length is 100 characters
+- Imports are structured in five blocks, each of them sorted as defined in
+  PEP 8:
+
+  1. Standard library imports
+  2. Django imports
+  3. Third-party imports
+  4. Imports from other BiscuIT apps (absolute imports)
+  5. Imports from the same BiscuIT app (realtive imports)
+
+- All string literals use single quotes
+
+For the layout of source trees and style recommendations specific to Django,
+the `Django coding style`_ is a good source of information, together with
+the `Django Best Practices`_ collection.
+
+
+Working with the Git repository
+-------------------------------
+
+The Git repository shall be used as a historic documentation of development
+and as change management. It is important that the Git commit history
+describes waht was changed, by whom and why.
+
+Feature branches
+~~~~~~~~~~~~~~~~
+
+All features and bug fixes should be developed in their own branch and later
+merged into the master branch as a whole. Of course, sometimes, it is
+sensible to not do that, e.g. for fixing mere typos and the like
+
+WIthin the feature branch, every logical step should be commited separately.
+It is neither required nor desired to do micro-commits about every
+development step. The commit history should describe the trains of thought
+the design and implementation is based on.
+
+Commit messages
+~~~~~~~~~~~~~~~
+
+Commit messages should be written as described in `How to Write a Git Commit
+Message`_.
+
+Commit messages should mention or even close any related issues. For merely
+mentioning progress on an issue, use the keyword `advances`; for closing an
+issue, use `closes`; for referring to a related issue for informational
+purposes, use `cf.`. This should be done in the body of the commit message.
+
+The subject of a commit message can (and should) be prepended with a tag in
+square brackets if it relates to a certain part of the repository, e.g. [CI]
+when changing CI/CD configuration or support code, [Dev] when changing
+something in the development utilities, etc.
+
+Manifestos governing development
+--------------------------------
+
+The FOSS community has created some manifestos describing several aspects of
+software development, to agree upon a baseline for these aspects. The
+BiscuIT developers have agreed to adhere to the following manifestos:
+
+- The `Sane software manifesto`_
+- The `Accessibility Manifesto`_
+- The `User Data Manifesto`_
+
+Not all theses from these manifestos are applicable. For example, most data
+about persons in a school information system are dictated by the school and
+probably governed by laws defining what and when to store. In that case,
+giving the user control over these decisions is not possible. Developers
+need to decide what should resonably be followed.
+
+
+Text documents
+--------------
+
+If there is no objective reason against it, all text documents accompanying
+the source use `reStructuredText`_.
+
+
+Contributing to upstream
+------------------------
+
+If possible and reasonable, code that can be of use to others in the general
+Django ecosystem shall be contributed to any upstream dependency, or a new
+generalised upstream dependency be created, under the most permissive
+licence possible.
