/* 
WARNING: The redirect map is deprecated!!!
To add a redirect, please add it to the object in the file `301redirects.json` in the root of the project.
The format is as follows:
"/docs/the/old/link/": {
    "destination": "/docs/new/link",
    "addedOn": "2022-10-01"
},
addedOn is optional but recommended, please use the format YYYY-MM-DD, this is used to track when the redirect was added.
