 The library uses a few PHP modules.  Either install these from packages, or
 build PHP with something like:
 
-    $ ./configure --enable-mbstring --with-openssl --with-xsl && make && make install
+    $ ./configure --enable-mbstring --with-openssl --enable-intl --with-xsl && make && make install
+
+# Running Tests
+
+    $ phpunit -c tests/phpunit.xml.dist tests/small
+
+Or, if you have Xdebug:
+
+    $ phpunit -c tests/phpunit.xml.dist --coverage-html ./coverage tests/small
