 # How to contribute
 
-First off, thank you for taking the time to contribute! If you have a function that you would like to see in codon, we have a few standards and guidelines that we would like you to follow before we consider your merge request. Failure to follow the contribution guide will result in your merge request being challenged or rejected.
+First off, thank you for taking the time to contribute! If you have a function that you would like to see in the National Reusable Code Library, we have a few standards and guidelines that we would like you to follow before we consider your merge request. Failure to follow the contribution guide will result in your merge request being challenged or rejected.
 
-We are looking for functions and/or classes which are useful for workflows in DIS specifically. Please do not submit the following...
-* End-to-end scripts cannot be implemented into the package. If you find something reusable within your end-to-end script, then please feel free to extract it and submit it to Codon with tests attached.
-* Multiple functions that are unrelated. For example, "This function takes an integer number and rounds it to the nearest whole number". Please do not include multiple functions unless they're methods of a class or are related to the same file (i.e. two methods of suppression)
+We are looking for reusable functions and/or classes which are useful across multiple workflows in NHS data processing and analytics. Please do not submit the following...
+* End-to-end scripts that cannot be implemented into the package. If you find something reusable within your end-to-end script, then please feel free to extract it and submit it with its unit tests attached.
 * Duplicated functionality. For example, if your function is already done by another well known package.
 * Irrelevant functionality. If the function you submit is unrelated to DIS, it will mostly likely be challenged or rejected.
 
-## Basic idea
+When making a submission, it is helpful if this is kept small, and that the content is all related / follows a theme / are different methods of a class. It will make review and acceptance more straightforward.
 
-1. [Fork](https://help.github.com/en/articles/fork-a-repo) codonPython on GitHub.
+## Eligibilty
+Anyone is free to suggest contributions this repository, access it, and utilise its contents. However, as a number of steps for the approval process take place within NHS England, if you're external it might be wise to email the repository owners to discuss your submission so that they can bring it through the governance and approval process within NHS England. Otherwise you might end up waiting until someone notices a new pull request and considers it.
 
-2. Write your documented function and tests (:heart_eyes:) on a new branch, coding in line with our **coding conventions**.
+The process for submitting new code is:
 
-3. Submit a [pull request](https://help.github.com/en/articles/creating-a-pull-request) **to the dev branch** of codonPython with a clear description of what you have done.
+1. Identify the reusable components within your code and refactor them to be standalone functions / classes (e.g. no integrated or dependent on the work they were originally a part of)
+2. [Fork](https://help.github.com/en/articles/fork-a-repo) this repo on GitHub.
+4. Write your documented function and tests (:heart_eyes:) on a new branch, coding in line with our **coding standards**.
+5. Submit a [pull request](https://help.github.com/en/articles/creating-a-pull-request) **main branch** of the National Reusable Code Library with a clear description of what you have done, fully completing all sections of the  `pull_request_template.md` (the empty template should appear automatically in the pull request).
+6. The maintainers of the repository will review the code, and, if it meets the basic standards set out here, take if for consideration to the Reusable Code Advisory Group within NHS England.
+7. If rejected, feedback will be provided, and once this has been actioned it can taken back to the Advisory Group
+8. IF accepted, the pull request will be merged into the main branch.
+9. At regular interverals, the code will be packaged up and released - the commit will be tagged with a semantic version, following the usual approach of trivial, minor and major (breaking) changes. These versioned packages will be published to PyPi and potentially other package repositories.
 
 We suggest you make sure all of your commits are atomic (one feature per commit). Please make sure that non-obvious lines of code are commented, and variable names are as clear as possible. Please do not send us undocumented code as we will not accept it. Including tests to your pull request will bring tears of joy to our eyes, and will also probably result in a faster merge.
 
-## Coding conventions
+## Coding standards
 
-We use the industry standard [PEP 8](https://www.python.org/dev/peps/pep-0008/) styling guide within the `codonPython` package. **Therefore, it’s imperative that you use the coding standards found within PEP 8 when creating or modifying any code within the `codonPython` package**. Autoformatters for PEP8, for instance [black](https://black.readthedocs.io/en/stable/), can easily ensure compliance. The reason we use PEP 8 coding standards is to make sure there is a layer of consistency across our codebase. This reduces the number of decisions that you need to make when styling your code, and also makes code easier to read when switching between functions etc.
+In short:
+- Follow PEP-8, and use Black to enforce this on your code
+- Have unit tests for all your functions / methods
+- Write [Numpy-style](https://numpydoc.readthedocs.io/en/latest/format.html#docstring-standard) docstrings for functions, including descriptions, inputs, outputs, and example usage
+- Methods used in the code should have been approved by the appropriate body, e.g. the Data Quality Steering Group for DQ rules. For external submissions, this might require a longer review process in which these are brought to those bodies.
 
-While you are creating code, we recommend that you understand the style guide standards for the following topics:

-
-We do ask that you include some basic tests with your contributions. While the logic of your contribution is important, some basic unit tests to verify functionality and data types for the inputs are requested for a baseline level of assurance and 'elegant failing'.

+## Governance
+New reusable code is discussed and signed off in the Reusable Code Assurance Group within NHS England. This group also sets the standards this code is made to.
+New code must have appropriate unit tests and all unit tests must pass before it can be merged into the main branch. These tests can be found in the `src/.../tests` folders.

-GitHub is a hosting site that allows for development and version control of software using Git. It allows users to edit and develop parts of code independently before submitting back to the master code, whilst using version control to track changes.

-The files that Sphinx builds the documentation from are located here. ReStructuredText `.rst` files are text files similar to markdown which allow formatting and interactivity with Sphinx. As with the functions in codon, improvements to the documentation files here are welcolmed.
+## ToDo
+This currently contains the old files from the Codon project - it needs updating to automatically generate code documentation, e.g. via Sphinx.
