After chosing the right way for you( I would suggest the second, as it simplier), use the shordcode [map_locator] in each post/page you would like to use it.
To update the keywords for searching, you need to do assets > js > map_location.js and update the keywords. In case the key doesn't work, you would need to update it. For doing that, you need to generate your own key, in https://developers.google.com/ -- you need to first generate places Api key and after that javascript Map Api key(they should be the same) After generating the key, replace it to shero_map_locator.php(at the script tag at the very bottom of it) and to map_location.js file.
After doing this, using the shordcode, must work basically everywhere you will need to.
