What part(s) of the article would you like to see updated?

When receiving a push event in a GitHub app, you'll receive an object with top level installation property:
"installation":{"id":...,"node_id":...}

When receiving an installation/installation_repositories event you'll receive an object with top level installation property:
"installation":{"id":...,"client_id":...,"account":...,"repository_selection":...,"access_tokens_url":...,"repositories_url":...,"html_url":...,"app_id":...,"app_slug":...,"target_id":...,"target_type":...,"permissions":...,"events":...,"created_at":...,"updated_at":...,"single_file_name":null,"has_multiple_single_files":...,"single_file_paths":...,"suspended_by":...,"suspended_at":...}

Both are documented with the description: "Installation" and the generic type "object". The only property in common is "id" (side node, I'm surprised that "node_id" isn't common, probably an implementation thing not sending it 🤔)

I'd much appreciate it if some of the properties were given a little more description, for example the entire schema of the installation object and the circumstances/conditions where some properties might not be sent. The same can be said for the following properties in the docs:
"enterprise": object
"organization": object
"repository": object
"sender": object
Which are all generically typed as "object"

I haven't found anywhere that describes the shape of these objects and the inconsistency can make an app break without warning.
