-A Leet Sheet is a document that fits on a single piece of paper and is intelligently designed to communicate the most important concepts about a topic.
+***
 
-PLDB now has links to Leet Sheets for over 100 languages.
+A Leet Sheet is a single page densely packed with intelligent information about key concepts in a topic.
 
+# What makes a great Leet Sheet?
+1. *One page*. Ideally single sided.
+2. *Concise Writing and Visuals*. No extraneous words or strokes.
+3. *Printable*. A PDF, PNG or other easily printable format should be provided or easy to generate.
+4. *Open source*. The source code should be viewable and improvable by everyone.

+# Help us add Leet Sheets!
+PLDB currently has links to Leet Sheets for over 70 active languages. But that means we need to add Leet Sheets for _hundreds_ more. Also, some of the Leet Sheets we currently link to don't meet all the guidelines above, and we'd love to swap those links for ones that do. If you could take a moment and add a `leetSheet [url]` to your favorite programming language's source file on PLDB and send a pull request, together we can build the world's biggest dataset of Leet Sheet links in no time at all!

+# Notes
 
 ? Why not use the term Cheat Sheet?
-A Leet Sheet is perhaps the most honest form of documentation one can make. To associate it with "Cheating", is not only inaccurate, but harmful. We need a great term for a great concept.
+A Leet Sheet is perhaps the most honest form of documentation one can make. To associate it with "Cheating", is not only inaccurate, but harmful because it discourages the creation and use of Leet Sheets. We need a great term for a great concept.
+
+? Can you generate Leet Sheets automatically from source code?
+Yes. Scroll is the language PLDB is written in and the Leet Sheet for Scroll currently is below and is autogenerated from the Scroll source code:

  summary Project Jupyter ( ( listen)) is a nonprofit organization created to "develop open-source software, open-standards, and services for interactive computing across dozens of programming languages."  Spun-off from IPython in 2014 by Fernando Pérez, Project Jupyter supports execution environments in several dozen languages.  Project Jupyter's name is a reference to the three core programming languages supported by Jupyter, which are Julia, Python and R, and also an homage to Galileo's notebooks recording the discovery of the moons of Jupiter. Project Jupyter has developed and supported the interactive computing products Jupyter Notebook, Jupyter Hub, and Jupyter Lab, the next-generation version of Jupyter Notebook.

  summary knitr is an engine for dynamic report generation with R. It is a package in the statistical programming language R that enables integration of R code into LaTeX, LyX, HTML, Markdown, AsciiDoc, and reStructuredText documents. The purpose of knitr is to allow reproducible research in R through the means of Literate Programming. It is licensed under the GNU General Public License.knitr was inspired by Sweave and written with a different design for better modularization, so it is easier to maintain and extend. Sweave can be regarded as a subset of knitr in the sense that all features of Sweave are also available in knitr. Some of knitr's extensions include the R Markdown format (used in reports published on RPubs), caching, TikZ graphics and support to other languages such as Python, Perl, C++, Shell scripts and CoffeeScript, and so on. knitr is officially supported in the RStudio IDE for R, LyX, Emacs/ESS and the Architect IDE for data science.

  summary Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool by the same name. Markdown is often used to format readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor. As the initial description of Markdown contained ambiguities and unanswered questions, many implementations and extensions of Markdown appeared over the years to answer these issues.
