*Knowen* allows you to export arbitrary subtree into single HTML file. Your browser can convert it into PDF for you. For example, there is an option **Save to PDF** at the **Print** menu in Google Chrome.

We are working now on one-click export to $\LaTeX$ and PDF. Meanwhile you will need to use a third-party converter. We recommend [Pandoc](http://johnmacfarlane.net/pandoc/), which is available on Windows, Mac and Linux. It can produce, among others, $\LaTeX$, **epub** and **docx** outputs. The downside is that you will have to run it from the console.

To convert an exported HTML file into $\LaTeX$, follow the steps below:

1. Open the file with your favorite text editor. Remove the last 9 lines at the end (starting with `<script src="http://cdn.mathjax.org/...`). Save this file with `.md` extension.
2. Remove the table of contents from the beginning of the file.
3. To obtain a $\LaTeX$ file, invoke Pandoc with the following command: `pandoc -f markdown_github+tex_math_dollars -s -V lang=english -o output_filename.tex input_filename.md`. Here `input_filename.md` is the file you saved at step 1, and the output will be written to `output_filename.tex`. If needed, substitute `english` with your language name (it will be passed to the **babel** package in $\LaTeX$). You can substitute `.tex` with other supported extension like `.docx` or `.epub`.
4. You might want to tweak the $\LaTeX$ source you have gotten before compiling it to PDF. Here is some advice:
	 1. You might want to comment out `\usepackage{lmodern}`
     2. Insert `\usepackage{cmap}` to support searching in PDF
