-# DOLIBARR ERP & CRM custom directory for external modules
-
-This directory is dedicated to store external modules.
-To use it, just copy here the directory of the module into this directory.
-
-Note: On linux or MAC systems, it is better to unzip/store the external module directory into
-a different place than this directory and just adding a symbolic link here to the htdocs directory
-of the module.
-
-For example on Linux OS: Get the module from the command
-
-`mkdir ~/git; cd ~/git`
-
-`git clone https://git.framasoft.org/p/newmodule/newmodule.git`
-
-Then create the symbolic link
-
-`ln -fs ~/git/newmodule/htdocs /path_to_dolibarr/htdocs/custom/newmodule`
-
-WARNING !!!
-Check also that the /custom directory is active by adding into dolibarr `conf/conf.php` file the following
-two lines, so dolibarr will also scan /custom directory to find external external modules:
-
-```php
-$dolibarr_main_url_root_alt='/custom';
-$dolibarr_main_document_root_alt='/path_to_dolibarr/htdocs/custom/';
-```
