+# Pygments CSS generator
+
+This is the correct way to generate all pygments CSS files.
+
+## How to generate CSSs files
+
+Before run `generate.py` remember to install all requirements.
+This can done with `pip install -r requirements.txt`.
+
+After this you can run `./generate.py`. Remember to run inside this folder.
+Because it uses relative path to place inside `static/pygments` folder.
+
+After that, go back to the Flex path and run `gulp pygments` to generate all `min.css` files.
+
+## How to add new styles?
+
+[See wiki](https://github.com/alexandrevicenzi/Flex/wiki/Code-Highlight#how-to-add-new-styles).
