You can change the settings of the theme in the colors/dark.yaml file.
To build, use sublate:

After building the theme you should have a output/jetbrains folder. Inside the output folder there should be a couple more folders, now you'll need to zip the contents of the resource folder into a .zip file. Make sure when you open the .zip file you see 3 folder: META-INF, schemes and theme. When everything checks out change the extension of the zip file to .jar.
To import the theme into your preferred JetBrains Editor go to File > Settings > Plugins and click the 3 dots. There should be an option called Install Plugin from Disk..., select this option and select the .jar file you created earlier and your theme should be imported.
