Leanpub Manual
  - A dedication is added through your book’s Settings page, and is put before the Table of Contents.
 
  - Adding About the Author text on the Settings page overrides the About You text on your account profile.
 
  - Coupons let you sell your book at a discounted price, or let reviewers get free copies.
 
  - Only e-mail your readers once or twice a month at most.
 
  - Markdown supports almost all the Kramdown extensions, with the exception of HTML blocks and 
<< becoming the left guillemet. 
  - Attributes should be alone on a line, with blank lines above and below.
 
  - Technical books are on 8.5”x11” paper with inch margins, leaving 6.5”x9” to work with.
 
  - With 300PPI images, an image can be 1950x2700 pixels, while the cover page should be exactly 2550x3300 pixels.
 
  - You can float and align an image on your page by using the 
width and float attributes. 
  - Cover images can be in either JPEG or PNG format and must be named 
title_page.jpg or title_page.png. 
  - If all your books are in stealth mode, then your profile is also invisible to the public.
 
  - When specifying whether libraries can purchase your book, consider that libraries can lend out an unlimited number of copies of your book without DRM.
 
  - You can add Google Analytics to your landing page.
 
  - Leanpub ignores all 
.git directories, and so you can use a Git repository as your manuscript directory. 
  - To add a motto or epigraph to the beginning of a chapter, simply center the text.
 
Markdown
  - An image is inserted by 
, or  to insert without a caption. 
  - To start a new part in your book, start a line with 
-# followed by the part title. 
  - Create 
frontmatter.txt, mainmatter.txt, and backmatter.txt files that just contain {frontmatter}, {mainmatter}, and {backmatter}. 
  - Surround text in carets (
^) to make it superscript. 
  - Adding two spaces at the end of a paragraph creates separation. This is useful when following a paragraph with another kind of text block.
 
  - You can center text by preceding it with 
C> . 
  - Once you start a numbered list, it doesn’t matter what number you put at the beginning of the line.
 
  - To put a code block in a list, indent it by 8 spaces, and place a blank line before and after the code block.
 
  - For a definition list, put the thing you want to define on a line by itself, and on the next line precede the definition with a colon (
:). 
  - Text in a blockquote is preceded with 
> . 
  - Text in an aside, or sidebar, is preceded with 
A> . 
  - In the same style as asides, use 
W>  for warnings, T>  for tips, E>  for errors, I>  for information, Q>  for questions, D>  for discussions, and E>  for exercises. 
  - Create a code block by placing matching numbers of tildes before and after the block.
 
  - You can put code in its own folder, and refer to it with either 
<<(code/filename.ext) or <<[title](code/filename.ext). 
  - To create a link without alternative text, surround the URL in angle brackets (
< and >). 
  - There must be a blank line before and after a footnote definition, and the caret symbol is required.
 
  - Identifiers that you can crosslink to are preceded with 
# and enclosed in curly braces ({ and }). 
  - To force a page break, add 
{pagebreak} on a line by itself. 
  - When defining a table, use vertical bars (
|) to separate columns; also place bars before the first and after the last column. 
  - To add more spacing between rows in a table, put a dash lined between them.
 
  - To exclude lines, you can precede the text with two 
% characters. 
  - To use inline or block LaTeX math, surround the LaTeX with delimiters 
{$$} and {/$$}. 
  - Curly quotes are automatically generated from straight quotes in your Markdown.
 
  - A hack to add more space between paragraphs is to add a blank table, defined as 
| |.
