| ## ATProto / Bluesky Support | ||
|
|
||
| Unlike ActivityPub, GoBlog won't act as a PDS (Personal Data Server), but will use your PDS's API to create a post with a link to newly published posts on your blog. As the Bluesky App View doesn't support showing updates yet, support for sending updates also isn't implemented yet. | ||
|
|
||
| In your blog config, add the following section: | ||
|
|
||
| ```yaml | ||
| atproto: | ||
| enabled: true # Enable | ||
| pds: https://bsky.social # PDS, bsky.social is the default | ||
| handle: example.com # ATProto "username" | ||
| password: TOKEN # The password for the handle, on Bluesky create an app password | ||
| ``` | ||
|
|
||
| ## Redirects & Aliases | ||
|
|
||
| Activate redirects by adding a `pathRedirects` section to your configuration file: | ||
