Attention: After upgrading to the current version, the command php composer.phar install must be run to make Part-DB work! If this is not possible, the folder `vendor/' Part-DB must be copied from a working Part-DB install with composer. Part-DB is a web-based database for managing electronic components. Since access is via the Web browser, you must install Part-DB on a Web server. Afterwards, the software can be used with any standard browser and operating system without the need to install any additional software.
