Installing phplot using cakephp3 wamp64



I have some issues installing phplot on windows (wamp64) for a cakephp3 application. The instructions indicate

"On Windows systems, you can simply download the release ZIP file, expand
   it using Windows Explorer, and copy the needed script file(s) out of 
 the contained phplot-* folder into place." 

q1)Where exactly is “into place mean” on wamp64?

q2) accessing phplot in cakephp3 projects (I cant find instructions)?
