-* Be very careful that Sugar doesn't do a very "clean" job so it's better to deactivate the strict standards erorr reporting in PHP to be able to use it. When I launch my script, I usualy do something like:

-* Last but not the least: you'll be able to instanciate the EntryPoint for only one instance of Sugar ! It uses GLOBALS variable such as $GLOBALS['db'] and I let you imagine what will happen if it's overwritten by another Instance of SugarCRM ;)

 # Classes
-## Inet\SugarCRM\EntryPoint
-That's the class all other classes need. It says where is Sugar and does the basic steps to "login" into SugarCRM. EntryPoint needs a logger because other classes log a lot of stuff.
+## Inet\SugarCRM\Application
+Gives general information about SugarCRM Installation.
+Others classes depends on this one.
 
 Usage Example:
 ```php
 <?php
 require_once 'vendor/autoload.php';
-use Psr\Log\NullLogger;
-use Inet\SugarCRM\EntryPoint;
+use Inet\SugarCRM\Application;
 
-$nullLogger = new NullLogger;
-// enter sugar
-$sugarInetEP = new EntryPoint($nullLogger, '/home/sugarcrm/www', '1');
+$sugarApp = new Application('/home/sugarcrm/www');
+echo $sugarApp->getSugarPath();
+if ($sugarApp->isValid()) {
+    echo $sugarApp->getVersion();
+}
 ```
 
-## Inet\SugarCRM\Application
-Gives general information about SugarCRM Installation. For now, it only gives the same path we set on $entryPoint.
+## Inet\SugarCRM\EntryPoint
+It says where is Sugar and does the basic steps to "login" into SugarCRM.
+EntryPoint needs a logger because other classes log a lot of stuff.
+The EntryPoint can only be loaded once for the entire program.
 
 Usage Example:
 ```php
 <?php
 require_once 'vendor/autoload.php';
 use Psr\Log\NullLogger;

 use Inet\SugarCRM\Application;
