Overall: Clean docs change — the "That's it!" → "Done." replacements and the parent company addition all look good in intent. However, there's a formatting issue in the frontmatter that should be fixed before merging.

Issue: Missing space after colon in frontmatter keys

The title and og:title fields lost the space between the colon and the opening quote. The other frontmatter fields (description, og:description, sidebarTitle) all retain the space. This inconsistency could cause YAML/MDX frontmatter parsing issues depending on the documentation framework.

# Current (lines 2, 4)
-title:"Set up an Atlassian OpsGenie connector"
-og:title:"Set up an Atlassian OpsGenie connector"

# Expected
+title: "Set up an Atlassian OpsGenie connector"
+og:title: "Set up an Atlassian OpsGenie connector"

Fix this →

Everything else looks good — the three "That's it!" → "Done." swaps are consistent and complete.

Overall: Clean docs change. The frontmatter spacing issue from the first commit (f5f6102) was properly fixed in 440ae9b. Everything looks good — ready to merge.

Changes verified:

1. Title update — title and og:title now include "Atlassian" as the parent company name ("Set up an Atlassian OpsGenie connector"), matching the existing sidebarTitle: "Atlassian OpsGenie" on line 6. Frontmatter spacing is correct (space after colon on all fields).

2. "That's it!" → "Done." — All three instances replaced consistently (lines 55, 105, 216). No remaining occurrences.

No issues found. LGTM.
