You can download wordpress from wordpress.org then we need to install in our local machine or server.
Now you need Wamp Server or Lamp Server to be installed in your local machine or server.
Then you can directly run the path like http://localhost/wordpressfoldername/ or if you have domain name then write domain name in web browser.
It will ask for Database , you need to create New database in your PHPMYADMIN installed in wamp or lamp server by default.
After that you can give that database name and phpmyadmin username and password for the wordpress configuration.
After that the last step is wordpress will ask email address and username and password for the final installation.
Thats it login with the set credentials and your site is working perfectly in just 2 minutes of after Installation.
