Move driver installation part and typo fix (#230)

Move the section on driver installation to be next to the part on library installation, to avoid misunderstandings by beginners e.g.(#229). Also fixed typo.

+
+Install Chrome and Firefox browsers downloading them from the official
+sites. There won't be a problem on all the platforms.
+
+Install specific drivers you need:
+
+- Google [Chrome driver][url-chromedriver]:
+
+  - `brew cask install chromedriver` for Mac users
+  - or download compiled binaries from the [official site][url-chromedriver-dl].
+  - ensure you have at least `2.28` version installed. `2.27` and below has a
+    bug related to maximizing a window (see [[Troubleshooting]]).
+
+- Geckodriver, a driver for Firefox:
+
+  - `brew install geckodriver` for Mac users
+  - or download it from the official [Mozilla site][url-geckodriver-dl].
+
+- Phantom.js browser:
+
+  - `brew install phantomjs` For Mac users
+  - or download it from the [official site][url-phantom-dl].
+
+- Safari Driver (for Mac only):
+
+  - update your Mac OS to El Captain using App Store;
+  - set up Safari options as the [Webkit page][url-webkit] says (scroll down to
+    "Running the Example in Safari" section).
+
+Now, check your installation launching any of these commands. For each command,
+an endless process with a local HTTP server should start.
+
+```bash
+chromedriver
+geckodriver
+phantomjs --wd
+safaridriver -p 0
+```
+
+You may run tests for this library launching:
+
+```bash
+lein test
+```
+
+You'll see browser windows open and close in series. The tests use a local HTML
+file with a special layout to validate the most of the cases.
