## Posit Cheatsheets
The cheatsheets make it easy to learn about and use some of our favorite packages. They are published in their respective PDF versions here: https://posit.co/resources/cheatsheets/, some are also available in the RStudio IDE under Help > Cheatsheets.
We are also starting to make some cheatsheets available in a more accessible, text-based HTML format. These are available at https://rstudio.github.io/cheatsheets/.
This repository contains the source files of the current, archived and translated versions.
The cheatsheets use the creative commons copyright. Please see the LICENSE document for more details.
## Translations
If you wish to contribute to this effort by translating a cheatsheet, please feel free to use the source Keynote file. To submit a translation, please use a Pull Request via GitHub. See the contributing guidelines for more information.
## HTML cheatsheets
If you wish to provide an HTML cheatsheet version, please create a Pull Request 
with a new `.qmd` file in the `html/` directory of this repository. Use one of 
the existing `qmd` files there as a starting point/template. These should not be duplicates of the pdf versions - they should be text-based so they are more accessible
to people with visual impairments. Use of images should be minimized, and any images should include appropriate alternative text.
## Tips for making a new cheatsheet
**Cheatsheets are not meant to be text or documentation!** They are scannable visual aids that use layout and visual mnemonics to help people zoom to the functions they need. Think of cheatsheets as a quick reference, with the emphasis on quick. Here's an analogy:
> A cheatsheet is more like a well-organized computer menu bar that leads you to a command than like a manual that documents each command.
Everything about your cheatsheet should be designed to lead users to essential information _quickly_. If you are summarizing the documentation manual, you are doing it wrong! Here are some tips to help you do it right:
### Getting Started
1. RStudio cheatsheets are hosted at https://github.com/rstudio/cheatsheets. You can submit new cheatsheets to the repository with a pull request. See the contributing guidelines for more information.
1. The files keynotes/0-template.key and powerpoints/0-template.ppt are official templates that contain some helpful tips.
1. You may find it easiest to create a new cheatsheet by duplicating the most recent Keynote / Powerpoint cheatsheet and then heavily editing it—that's what I do!
### Process
Budget more time than you expect to make the sheets. So far, I've found this process to be the least time consuming:
1. **Identify which functions to include** by reading the package web page and vignettes. I try to limit my cheatsheets to the essentials.
2. **Organize the functions** into meaningful, self-explanatory groups. Each group should address a common problem or task.
3. **Think about how to visualize the purpose of each function.** Visual mnemoni
