How to enable XDebug?

Question

PHP

Please help me set it up.
OS: Mac OS X
Server: MAMP 3.5
IDE: VSCode
Browser: Chrome
PHP: 5.3.29
Enabled in php.ini (and restarted the server)

[xdebug]
zend_extension="/Applications/MAMP/bin/php/php5.3.29/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"
xdebug.remote_autostart=1
xdebug.remote_enable=1
xdebug .remote_host=localhost
xdebug.remote_port=9000
