+# Simple Auto Scroll
+
+### 1. What is it?
+
+A speed-customizable auto-scroll Google Chrome extension.
+
+### 2. Why?
+
+A lot of times I find myself reading long
+[texfiles](http://www.textfiles.com/), and after a while, I kind of
+wish I could just read them as if they were a movie. I've tried with
+the mouse (middle click) thingy, but it's just not practical and
+adjusting the speed is very tricky - not to mention that a lot of
+times it's just too fast.
+
+## 3. Features
+
+This extension allows you to easily change the auto-scroll speed and
+save it in three different modes; slow, medium and fast. A single
+click will stop the auto-scrolling.
+
+### 3. Installing
+
+**Option 1** just install it from the [chrome web store](https://chrome.google.com/webstore/detail/dccjkemhmffnljlnnoffljpkhkfpldff)
+
+**Option 2** – install it from source:
+
+* clone/download this repo,
+* open Chrome and go to `chrome://chrome/extensions/`,
+* enable "Developer mode",
+* click "Load unpacked extension",
+* select the `extension` folder in this repo.
+
+### 4. Compatibility
+
+It works on all Chrome distribution channels: Stable, Beta and Dev.
