 =================
 
-A typesetted F# Cheatsheet in PDF and HTML formats using F# literate tools
+An F# Cheatsheet in Markup and HTML formats
 
 ## Introduction
 
-This is an attempt to replace the old and obsolete [F# Cheat Sheet](http://www.samskivert.com/code/fsharp/fsharp-cheat-sheet.pdf).
-
 The raw content of this cheatsheet can be edited at [fsharp-cheatsheet.md](docs/fsharp-cheatsheet.md).
 
-In order to build PDF and HTML documentation, please run the build script in [build.cmd](tools/build.cmd). We assume that `pdflatex.exe` is in PATH variable to be able generate PDF files.
+HTML version is online at https://spiraloss.github.io/fsharp-cheatsheet
+
+## Contributing
+
+This resource was, is and should remain a community effort. If you're learning F# and something important you didn't learn about isn't covered, you're the very best person to point that out and phrase it in a way that someone new can get running with. If someone posts a PR, the more diversity of reviewers we get, the better. That said, the best PRs are small ones that touch one piece at a time and can hence be reviewed and merged rapidly.
 
-PDF version can be downloaded [here](https://github.com/dungpa/fsharp-cheatsheet/raw/gh-pages/fsharp-cheatsheet.pdf).
-HTML version is online at http://dungpa.github.io/fsharp-cheatsheet/.
