Contribution are most welcome! All `tldr` pages are stored in Markdown right here on GitHub. Just open an issue or send a pull request and we'll merge it as soon as possible.
1. Focus on the 5 or 6 most common usages. It's OK if the page doesn't cover everything; that's what `man` is for.
2. When in doubt, keep new command-line users in mind. Err on the side of clarity rather than terseness.
3. Try to incorporate the spelled-out version of single-letter options in the example's description.
4. Introduce options gradually, starting with the simplest commands and using more complex examples progressively.
5. Use short but descriptive values for the tokens, ex. `{{source_file}}` or `{{wallet.txt}}`.
6. Be specific: avoid explaining general UNIX concepts that could apply to any command (ex: relative/absolute paths, brace expansion, character escaping...)
You're free to modify or redistribute the content. That being said, but why not contribute over here? :) Say if you wanted to have `tldr` pages in `groff` format, why not have a client that uses [pandoc](http://johnmacfarlane.net/pandoc/) and periodically updates straight from this repo?
