You need to follow these steps to install SMF:

1. Download the installation from the site of the vendor. SMF can be obtained from:

http://download.simplemachines.org/

We recommend downloading the tar.bz archive.

2. Once you have downloaded the archive that contains the installation, you need to upload it into your disk space.

You can upload the archive and use the web hosting Control Panel's File Manager to extract the package. Check the permissions of the installation's folders. If they are set to 700, change them (recursively) to 755 or 775. You can use the File Manager for this operation.

The best way to upload big files or multiple files is via FTP. If you are not sure how to upload the files, please check the Uploading files section from our online documentation.

If you are installing the application in your main domain, or in a subdomain, you may need to delete the default index.php file first. You can do this either via FTP or through your web hosting Control Panel's File Manager.

3. Create a new MySQL database and user for the SMF application. For security reasons, MySQL databases and users can be created only through the hosting Control Panel. Detailed instructions on the process are available in our Creating a MySQL database/user article.

Once you have the database and MySQL user created, you should associate the MySQL user with the database by following the instructions from our Associating a MySQL user with a database article. Unless you have a reason to do otherwise, you can select all available privileges for the new MySQL user.

4. You need to access with your browser the directory in which the extracted SMF files are located. You should see the first page of the SMF installation.
