put a file called dat in a folder in your webroot called .well-known so: example.com/.well-known/dat the format of the file is: the dat url for your website (you can use the dat cli to upload your website) the ttl (time to live, amount of time to cache the site basically) which means the contents of example.com/.well-known/dat would look like: dat://d72c5cebc4b19c3bdbd5e6eae3ccf75ba7a311e73bb87ae29aac02c50174d4da/ ttl=3600 you would now be able to access your website on dat using dat://example.com in something like beaker browser happy dat-ing! note: example.com/.well-known/dat has to be accessible over https and not http, thanks to inky for this tip:3
