Poem

🐰 A quote was plucked from localhost's home,
Now naked it stands in dotenv's domain,
No syntaxes harmed, just cleaner to roam,
The example now shines, simpler and plain! ✨

🧹 Nitpick comments (1)

docs/extending-seerr/database-config.mdx (1)

33-33: Consider removing quotes in the default description for consistency.

The inline comment still shows the default as "localhost", which may imply quoting even though the example now uses an unquoted literal. Suggest updating the comment to avoid mixed signals.

✏️ Suggested tweak

-DB_HOST=localhost # (optional) The host (URL) of the database. The default is "localhost".
+DB_HOST=localhost # (optional) The host (URL) of the database. The default is localhost.

comment for the DB_HOST environment variable so the default value is shown
without quotes to match the unquoted example; locate the line containing the
DB_HOST token (DB_HOST=localhost) and change the comment text from '"localhost"'
to localhost so the description is consistent and doesn't imply the value must
be quoted.
