+    ReactPhysics3D has an internal logger that can be used to get logs from the library while the application is running. This can be useful for
+    debugging for instance. \\
 
     The logger is part of the \texttt{PhysicsCommon} class. By default there is no logger set. If you want to create your custom logger to receive logs
     from ReactPhysics3D, you can inherit the \texttt{Logger} class and override the \texttt{Logger::log()} method. Then, you have to use the
     \texttt{PhysicsCommon::setLogger()} method to set the logger. \\
 
+    Getting the logs is the way for you to see the errors reported by the library and therefore, you should not just ignore the errors from the logs.
+    You should at least redirect the logs (warnings and errors) in the standard output while debugging your application as described in the example
+    below. \\

     \begin{sloppypar}
     If you don't want to create your custom logger class, you can use the default logger of ReactPhysics3D (class \texttt{DefaultLogger}). With this
     logger, you can output the logs into
-    a file or a std::stream. The logs can have different format like raw text of HTML. In order to create a default logger, you need to call the
-    \texttt{PhysicsCommon::createDefaultLogger()} method. Then, you can customize this default logger and finally, you need to set this logger using the
+    a file or a std::stream. The logs can have different format like raw text of HTML. In order to instantiate the default logger, you need to call the
