First Things First

Welcome. WordPress is a very special project to me. Every developer and contributor adds something unique to the mix, and together we create something beautiful that I’m proud to be a part of. Thousands of hours have gone into WordPress, and we’re dedicated to making it better every day. Thank you for making it part of your world.

— Matt Mullenweg

Installation: Famous 5-minute install

Unzip the package in an empty directory and upload everything.
Open wp-admin/install.php in your browser. It will take you through the process to set up a wp-config.php file with your database connection details.
1. If for some reason this doesn’t work, don’t worry. It doesn’t work on all web hosts. Open up wp-config-sample.php with a text editor like WordPad or similar and fill in your database connection details.
2. Save the file as wp-config.php and upload it.
3. Open wp-admin/install.php in your browser.
Once the configuration file is set up, the installer will set up the tables needed for your blog. If there is an error, double check your wp-config.php file, and try again. If it fails again, please go to the support forums with as much data as you can gather.
If you did not enter a password, note the password given to you. If you did not provide a username, it will be admin.
The installer should then send you to the login page. Sign in with the username and password you chose during the installation. If a password was generated for you, you can then click on “Profile” to change the password.

Updating

Using the Automatic Updater

If you are updating from version 2.7 or higher, you can use the automatic updater:

Open wp-admin/update-core.php in your browser and follow the instructions.
You wanted more, perhaps? That’s it!

Updating Manually

Before you update anything, make sure you have backup copies of any files you may have modified such as index.php.
Delete your old WordPress files, saving ones you’ve modified.
Upload the new files.
Point your browser to /wp-admin/upgrade.php.

Final Notes

If you have any suggestions, ideas, or comments, or if you (gasp!) found a bug, join us in the Support Forums.
WordPress has a robust plugin API that makes extending the code easy. If you are a developer interested in utilizing this, see the Plugin Developer Handbook. You shouldn’t modify any of the core code.

Share the Love

WordPress has no multi-million dollar marketing campaign or celebrity sponsors, but we do have something even better—you. If you enjoy WordPress please consider telling a friend, setting it up for someone less knowledgable than yourself, or writing the author of a media article that overlooks us.
