The first step of creating a tool is to give it a name and short, clear description of what it does. There are some other optional fields for additional metadata.
By default, tools on the platform will have the Ontologic logo as their thumbnail image. However, if you have put the effort into creating a custom logo for your tool, you can upload an image file.
If you have written any documentation for your tool, you can add a link that will be visible on the tool's configuration interface.
