You can use a third-party service like DeployHQ to integrate your repository (Git, SCM, etc) and deploy to your Pressidium WordPress site.
Take a look at DeployHQ's support documentation. You will need to supply the following Pressidium-related information:
Protocol: SSH/SFTP
Hostname: your WordPress site's SFTP address.
Port: your WordPress site's SFTP port number.
Username: your SFTP username
Password: your SFTP password
Deployment paths:
acme_shop_2-dev-wwwfor the Staging environmentacme_shop_2-wwwfor the Production environment
Please note that if you are using a default, account wide "master" SFTP account (an account with the u prefix), the paths are different since they include the top level website information as well:
/acme_shop_2-dev/acme_shop_2-dev-wwwfor the Staging environment/acme_shop_2/acme_shop_2-wwwfor the Production environment
