WordPress is a free and open-source web content management software (CMS) which anyone can download and install on their own server. Using WordPress, you can create blogs and websites ranging from a simple personal blog, a portfolio site, to a full-fledged eCommerce website, or a news magazine that serves billions of web pages per month.
According to W3Techs, as of 2021, more than 40% of the websites in this world are built using WordPress. That means every third website you visit on day to day basis is likely built using WordPress.
WordPress is released under the GPL v2 license. As a WordPress professional, this means, you can use WordPress in any way you like, including for commercial purposes. Also, you can modify it and even distribute your modified copy, and even charge for your modified copy as long as you provide these same freedoms to your users.
In our practical use, we should never modify core files of WordPress or for that matter any frameworks we use. Most frameworks, including WordPress, provide an API that allows developers like us to change it’s behaviour without altering any of its source files. We will learn about these capabilities in this course soon.
WordPress is free software, and there are thousands of volunteers working in the official support forum where you can post your questions and get help from theme and plugin developers, fellow WordPress users, and other volunteers.
rtCamper developers can also request help in our Slack’s #engineering channel. But unless it’s urgent, it’s better to mingle with the community. Why limit yourself to the knowledge of 100 people when you have thousands of smart folks to help you.
When requesting help, you can follow the WPBeginner article on how to ask for help properly. Please remember that most people out there helping you are volunteers and they do not owe you anything. Be nice. Always!
