-* Rename configuration files
+* Option B - Using a existing VirtualHost
+
+Assuming you have a website running you need to find the path where is located the following components:
+
+DocumentRoot  --- directory where static files and PHP scripts are located
+CGI-BIN       --- directory with execution permission for CGI scripts
+ISIS dabases  --- directory on the server where ISIS databases are located
+
+Then move/copy or create symbolic links to the isis-oai-provider directories:
+
+    Ex. Assuming a website with this directory structure:
+    /home/sites/
+               /site1/
+                     htdocs/
+                     cgi-bin/
+                     bases/
+
+   $ cd /home/sites/site1/
+   $ cd htdocs
+   $ ln -s /opt/bireme/isis-oai-provider/htdocs/isis-oai-provider/ .
+   $ cd ..
+   $ cd cgi-bin
+   $ ln -s /opt/bireme/isis-oai-provider/cgi-bin/isis-oai-provider/ .
+
+
+
+3. Rename configuration files
 
 ```
     $ cd htdocs/isis-oai-provider/
     $ mv oai-config-sample.php oai-config.php
     $ mv oai-databases-sample.php oai-databases.php
 
 ```
+
+4. To test the application call your browser and inform your server name like: **http://your_server_name/isis-oai-provider/**
+
+  Ex. http://isis-oai-provider.local/isis-oai-provider/
