+This is a virtual environment by [Vagrant](https://www.vagrantup.com/) that enables Non-Unix like OS such as Windows to compile `.tex` (LaTeX) file into `.pdf` (PDF).
+
+When provisioning this VM, all of required tool sets are installed by shellscript.
+
+So you can easily create PDF and achieve it through the shared folder in the host OS.
+
+Important Note
+---
+
+**Sample LaTeX sources and compiling shellscript are extracted into [another project](https://www.github.com/imaizume/tex-sources).**
+
+Just clone it into shared folder *as a git submopdule*.
