Basically, all you need is a standard web hosting plan.
More specifically, your web server should support PHP 5.2+, MySQL 5+ & Apache 2+ (which is very common). More info about these requirements here.
If you're familiar with bower, just type: bower install b2evolution
You can download releases either from GitHub or from b2evolution.net :
Upload everything to your web server and call the installation script that you will find at /install/index.php on your website. Then you just need to enter your database connection details and the installer will take care of everything for you.
Now, you might ask for more details here... Totally legitimate! Please check out our Getting Stated - Installation Guide.
Hint: It is possible to install b2evolution in less than 3 minutes. Probably not the first time though. (And the same is true for anyone else claiming a 5 minute install process.)
b2evolution includes an automatic upgrade feature which you can use to automatically download the lastest stable version and perform the upgrade operations.
You can download any newer version (including beta releases), overwrite the files of your current installation (after backup) and then run the install script.
The installation script will detect that the b2evolution database is already installed (any version) and offer to upgrade it to the current version.
There are several other upgrade options.
All bug fixes and all new code are made available through GitHub before being packaged as releases. If you are interested in cutting-edge versions, we recommend you follow us on GitHub.
