Accessing and Editing the JSON File
Viewing and changing specification information in the Blueprint Definition JSON File.
This How-To entry describes how you can download, edit, and upload the JSON file with changes to your Blueprint specifications.
Download the Blueprint Definitions JSON file
Navigate to the Blueprint Definitions page and click the "Download Blueprints" icon 
near the top of the screen. This will save the blueprint-defintions.json file to your local hard drive, typically the Downloads folder.
Before making changes to this file, we recommend making a copy of the version you downloaded and setting that aside, just in case you need to revert back to the previous configuration.
Edit the file
Open blueprint-defintions.json in a text editor of your choice to view and edit. For example, on a Mac you can use TextEdit; and on Windows machines, Notepad.
Save and close the file.
Upload a new version of the file
Back on the Blueprints Definition page, you may now upload your JSON file via by clicking on the "Upload Blueprints" icon 
near the top-right corner of the page.
A modal window will appear with a message about how the existing JSON file will be overwritten by your new one. Tick the checkbox and click OK to proceed.
The file does not have to be named "blueprint-definitions.json" when you upload it. It will, however, always download as "blueprint-definitions.json".
