Prerequisite

Dolibarr was built to work on following components :

= OS = For example: Linux, BSD, Windows, MacOS, Aix, ...
 * Every OS is supported.

= Database = If using option mode=STRICT returns some warnings or error, please report them to us.
 * Mysql (any Mysql options/parameters supported)
 * PostgresSql
 * MSSql (experimental support not working yet)
 * Database size need is lower than 1Mb per 100 customers/suppliers.

= PHP =
 * Version
 * Support for user sessions must be enabled (it is the default value for PHP)
 * Works however magick_quotes parameter is set
 * Works however register_globals parameter is set
 * Works however safe_mode parameter is set


 * PHP configuration must allow use of a max of Mb of memory (parameter PHP memory_limit).

= Disk storage = However, it will need more disk space if you upload joined files or to store generated PDF or ODT documents. Storage will depend on number and size of attached files.
 * Program files use less than 80Mb on disks.

= CPU = Any hardware configuration is enough to make Dolibarr work for less than 50 users, even an old intel/pentium processor. If you have more than 50 users, a 1GHz CPU or more is recommended.
