Moka is quite a large project, and as it's sole developer if you'd like to support me & therefore the project, donations are much appreciated. Those few bucks do motivate me to keep spending time on it as it shows that there are folks who appreciate the work I'm doing –and it helps keeps my design-fuel (coffee) in supply.
If you'd like to show your appreciation by donating to the project or purchasing Moka's products (instead of opting for the free download), you ensure its continued development and show that you support independent open source developers.
Choose a Currency
Anyone can donate, however it may be more comfortable for you to donate in your native currency (via PayPal or with your credit card). Having said that, there are still limitations to which currencies are available.
