First of all, thank you for wanting to contribute to the card database!
We have an internal framework for managing Pokémon TCG data called the TCG Collector tools. These tools work with specific files for expansions, cards, images, and other kinds of resources.
You can contribute to the database by creating these files according to the TCG Collector tools resources specification. You don't need to install or run anything; you can simply create these files by using the documentation as a reference.
Before you create any of these files, please let us know what you would like to work on. An overview of all card database related tasks and issues that you might be able to help with can be found here.
It's also highly recommended to read our card database conventions. These conventions give you an overview of what values to use, such as card types and Pokémon stages.
Some resources need to embed other resources. For example, when creating card resource files, the contents of the expansion resource files are needed. You can view and download various resource files that have been exported from the TCG Collector database here.
Please do not hesitate to contact us if you have any questions.
I want to scan card images
If you want to scan missing card images or images of better quality, please read our scanning instructions. You can also find an overview of all missing card images here.
Please consider properly editing the images before sending them to us. However, if you lack the knowledge or time, you can send them to us as they are. If the images are properly edited and are ready to be added to the database, please consider creating the proper image resource files for them.
Sending us your files
If you want to send your files to us, you can do so by uploading them to a cloud storage service of your choice (such as Google Drive), and by providing us the link to it.
