+## Overview
+
+> This article aims to provide an exhaustive list of helpful tools, packages, and resources for developers, authors, maintainers, reviewers, and stakeholders in the R Package development workflow.
+
+Welcome to the world of R Package Development! Whether you're a seasoned R programmer looking to expand your toolkit or a newcomer eager to dive into the exciting realm of package development, you've come to the right place. In this comprehensive guide, we'll unveil the essential resources every R package developer needs to master their craft. From tutorials and books to online communities and tools, we've curated a treasure trove of resources to help you embark on your journey towards becoming a proficient R package developer.
+
+Throughout this article, I will provide a walkthrough of the various packages, tools, resources, and axioms I have encountered over my years as an R package software engineer.
+
+## R User vs. R Developer
+
+In the world of R programming, there are distinct roles and distinctions between an *R User* and an *R Developer*, each with its own set of responsibilities, skills, and objectives.
+
+To distinguish, R developers *develop* new innovative solutions while R Users *use* the tools and packages that the developers created. This article is aimed towards the development side of the spectrum and attempts to provide a comprehensive, curated toolbox for the R Developer, specifically in regard to developing R Packages.
+
+In summary, while both R users and R developers utilize R for data analysis and statistical computing, they differ in their focus and expertise. R users primarily leverage R for data analysis tasks, while R developers specialize in creating and maintaining R packages to enhance the functionality and capabilities of the R programming language for a broader audience of users.
+
+### R Users
+
+- **Definition:** An R user is someone who primarily utilizes R for data analysis, statistical modeling, visualization, and other tasks related to data science, research, or analytics.
+
+- **Skills & Responsibilities:**
+ - Proficient in using R for data manipulation, exploration, and analysis.
+ - Familiarity with statistical methods and techniques for interpreting data.
+ - Ability to create visualizations and plots to communicate insights effectively.
+ - Understanding of data structures, functions, and packages within R.
+ - May use R for tasks such as data cleaning, hypothesis testing, regression analysis, and machine learning
+
+- **Objectives:**
+ - Analyze and interpret data to derive meaningful insights and make data-driven decisions.
+ - Communicate findings through reports, presentations, or visualizations.
+ - Utilize R packages and libraries to streamline analysis workflows and enhance productivity.
+ - Collaborate with colleagues or stakeholders to address specific analytical needs or research questions.
+
+### R Developer
+
+- **Definition:** An R developer is someone who focuses on creating, maintaining, and extending R packages, libraries, and tools for the broader R community.
+
+- **Skills and Responsibilities:**
+ - Proficiency in programming with R, including knowledge of object-oriented programming principles, functions, and package development.
+ - Understanding of software engineering practices such as version control, testing, and documentation.
+ - Ability to design, implement, and maintain R packages to address specific needs or solve particular problems.

+ - Ensure the reliability, efficiency, and usability of R packages through rigorous testing, documentation, and code review.
+ - Engage with the R community to gather feedback, address issues, and collaborate on package development efforts.
+ - Stay updated on emerging trends, best practices, and advancements in R programming and package development.
+
+## Getting Started
+
+Now that you understand the difference between an *R User ans R Developer*, a question arises: "How can one go from being a user to a developer?".
+
+The answer is simple, create something! In this case, create an R Package.
+
+Once you have accumulates more than 2-3 common functions that operate within the same context, that is a primary indicator that you should structure your project as an R Package.
+
+After you have more than one function it starts to get easy to lose track of what your functions do. Similarly, it can start to become difficult to track down, name, and organize the functions and you may be tempted to put all of the functions in one file and just source it. Instead, I propose the best solution is to create an R package.
+
+### What you Need
+
+To begin creating an R Package, you need:
+
+- [R](https://www.r-project.org/) and [RStudio](https://www.rstudio.com/) installed on your machine
+- [Git](https://git-scm.com/) and [GitHub](https://github.com)
+- Some initial R functions
+- R Development Packages:
+ - `devtools`
+ - `usethis`
+ - `roxygen2`
+ - `pak`
+ - `knitr` and `rmarkdown`
+
+From there you can continue to naming your package, scaffolding out its structure, adding functions, documentation, metadata, data, license, vignettes, etc.
+
+## Pre-Requisite Resources
+
+To start, R package developers need to be familiar with the fundamentals of package development, and therefore should be familiar with some of the highest regarded resources available to read.
+
+Anyone who is serious about developing production grade R packages needs to be familiar with most of, if not all of the following resources and guides:
+
+
+
+### Writing R Extensions Manual
+
+The [Writing R Extensions Manual](http://cran.fhcrc.org/doc/manuals/R-exts.html) is perhaps the most crucial resource listed above, and has even been considered the *Bible of R Package Development*.
+
+As Hadley puts it in his book [Writing R Packages](http://cran.fhcrc.org/doc/manuals/R-exts.html):
+
+> *"The best resource for the official details of package development is always the official writing R extensions manual. However, this manual can be hard to understand if you’re not already familiar with the basics of packages. It’s also exhaustive, covering every possible package component, rather than focusing on the most common and useful components, as this book does. Writing R extensions is a useful resource once you’ve mastered the basics and want to learn what’s going on under the hood.”*
+>
+> *— Hadley Wickham*
+
+Thanks to [Colin Fay](https://colinfay.me/), a more elegant version of the original manual has been created as a bookdown site and published online at .
+
+*Note: The other manuals listed on the [CRAN Manuals website](https://cran.r-project.org/manuals.html) contain a lot of hidden gems that are often overlooked by R developers. These resources contain some of the most crucial, foundational knowledge that anyone using R should eventually be made aware of, therefore I highly recommend you check those out in addition to Writing R Extensions*.
+
+### R Packages Book
+
+The "R Packages" (2nd Edition) Book outlines the importance of packages in R as the fundamental unit of shareable code, combining code, data, documentation, and tests.
+
+It highlights the vast array of over 19,000 packages on CRAN and encourages readers to develop their own packages for easier code sharing and organization. The book aims to automate package development as much as possible, utilizing the `devtools` and `usethis` packages and the RStudio IDE for a more efficient workflow.
