Your new package is there! You can edit the package properties in the package manager. Use the edit button in the upper right corner of the package details panel to open the package editor.
Here is what you should do:
Of course, the most interesting thing is how to add, edit and develop DRC scripts within your macro package. When the package was initialized, a "drc" folder with a single DRC script has been created. You will find this folder in the macro editor in the DRC category under the name you have given the package. The name of the sample DRC script is "new_drc".
In the package details you will find the local path to your package data under "Installation". You can use any versioning system to manage your files there.
Once you have finished your package, don't forget to specify the package version so users of you package will be informed of updates. Finally you can publish the package files to a place of your choice and submit the download URL to the Salt Mine server.
