+# 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, caste, color, 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 andreas@gdamsbo.dk. 
+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.

+## Version 24.10.1
+
+First proper public version. The package is mainly build for an easy to use 
+shiny-interface, but can as easily be used directly in *R* with the main 
+`prioritized_grouping` function. This function is mainly a wrapper around the `ROI`
+package and the `ROI.plugin.symphony` plugin. 
+
+File types accepted in the shiny-app are .csv, .xls(x) and .ods.
+
+This project was initially developed after a co-worker told me, he would be 
+grouping students by individual priorities by hand and was preparing to spend 
+most of a day doing so. I insisted on having a go at solving that problem in 
+*R*. Now some of the some functionality is baked into Teams (that is what I am 
+told at least), though that is not because of me. I still think is small app has 
+its value, as it allows for the so-called "pedagogical redraw", where some 
+students are manually grouped in consideration of other factors than only the 
+given priorities before the algorithmic assignment.
+
+This, as said, is a first official version and working example. 
+More documentation is needed and will be added after further feedback. And 
+please, feedback is most welcome!

-# First try with shinylive
+# Group allocation based on individual subject prioritization
 
-Reviving an old project to use shinylive with R
+This project was initially developed after a co-worker told me, he would be grouping students by individual priorities by hand and was preparing to spend most of a day doing so. I insisted on having a go at solving that problem in *R*. Now some of the some functionality is baked into Teams (that is what I am told at least), though that is not because of me. 
 
+The functionality has later been further extended to allow for the so-called "pedagogical redraw", where some students are manually grouped in consideration of other factors than only the given priorities before the algorithmic assignment. This single addition makes it quite useful in schools and other educational institutions, as some customisation is allowed before the grouping.
 
-## Shortcoming
+## Shiny version
 
-This project requires ROI.plugin.symphony to solve the problem, which depends on the RSymphony project (which again adapts SYMPHONY MILP), which is not [compiled for webR](https://repo.r-wasm.org/).
+I am hosting a shiny version of this package, that allows to use the majority of functions.
+
+[Use the app here](https://agdamsbo.shinyapps.io/prioritized-grouping/)
+
+I have also attempted to package this as a shinylive program, but the "Symphony" solver has not been build to run in `{webr}`. When/if this happens, I will have another go.
+
+## Install the `{prioritized.grouping}` package
 
-Clone the project and run the solver with
 ```
-shiny::runApp(appDir = here::here("R/"),launch.browser = TRUE)
+pak::pak("agdamsbo/prioritized.grouping")
 ```

-## Here is a little example which shows a fundamental difference between

-## When invoked, "open.account" defines and returns three functions

-## This is even true when "open.account" has returned.  The only way
-## to access the value of "total" is through the accessor functions
-## withdraw, deposit and balance.  Separate accounts maintain their
-## own balances.
