While this book will cover most of the concepts with how Krita works, you will probably stumble on an area that might not be included. The feature might be new or something that has changed. There are three main areas that people go to when searching for help.
The Chat room is the fastest place to ask your questions. These can be related to installation issues, hardware issues, or building steps that might be hard to find. To access the chat room, you can go to the Krita website; there should be a link in the contact area on how to get connected or find the link on the Get Involved tab. Keep in mind that the chat room isn’t always going to get you an immediate answer. Many of the developers and volunteers may not be at their computer. If you do not get a response in a few minutes, you can take the next step.
The Forum can be a little better than the chat room since the conversations can be continued over days or weeks. You can search through the Krita forum and see if anyone else is experiencing the same issue. If you cannot find your solution, you can ask a question yourself in a new forum post. To access the forum, visit https://forum.kde.org. Click the Graphics & Multimedia area. Then click on the Krita forum. You can look at news, post your artwork to share, or visit the General Help topic.
The mailing list is a way to stay on top of Krita improvements via e-mail. There are two main types of mailing lists that exist: the mailing list on krita.org and the developer mailing list. The mailing list on krita.org is designed so you will be notified when new releases come out. If you don’t feel like checking the website to see if a new version has been released, the mailing list is a good place to sign up. You can sign up for this mailing list on Krita’s homepage. It usually includes information on what has changed and instructs you on how to download the new version.
The second mailing list, kimageshop, is designed for developers who want to be involved working on the application. At one point Krita was named "kimageshop", so the mailing list has retained that name. You can talk with the developers in the chat room to find out if this is right for you.
