Continuing the discussion from About Dolibarr:
Hi @Bohdan, welcome to TALER ICH. This category is not public yet, only available to you and your group (@i.dolibarr). You may invite other contributors if you like, and edit the post linked above which describes the TALER Integrations > Dolibarr category. Be careful with the first line that shows in TALER Integrations 
Do not hesitate to ask anything, modify the category description to your liking, etc. You may for example link to the code repository and describe the plan. Feel free to see what others have done.
TALER Integrations > WooCommerce already integrated GNU Taler, so it could serve as a starting point. But behold! TALER Integrations > TalerPHP just came in with your grantees’ cohort to develop a PHP library. You should work with @miro on this.
Happy hacking!
