Exercise 1: Explore the Remote Explorer — Possible Solution
====================================================================

STEPS
------------------------------
1. Open the Extensions view (Ctrl+Shift+X, Chapter 4) and search for
   "Remote Development." Install the extension PACK (a bundle
   covering Remote-SSH, Dev Containers, and WSL together, per this
   chapter's own three tools).
2. A new "Remote Explorer" icon appears in the Activity Bar (Chapter
   1). Click it.
3. At the top of the Remote Explorer, a dropdown lets you switch
   between "SSH Targets," "Dev Containers," and (on Windows) "WSL
   Targets." Select "SSH Targets."
4. If you completed the site's own ssh1 course and have host entries
   in ~/.ssh/config (e.g. a "Host myserver" block with a Hostname and
   User), those entries appear automatically in this list, with no
   separate configuration needed inside VS Code itself.
5. If no ~/.ssh/config exists yet, the list is empty, with an option
   to "Add New" a host manually — this would prompt for a connection
   string like user@hostname.

WHAT TO NOTE
------------------------------
The exact same file (~/.ssh/config) that plain command-line ssh reads
is what populates this list — VS Code isn't maintaining a separate,
parallel host list of its own. This is a direct, concrete instance of
this chapter's own point that Remote-SSH "reuses the exact same
hosts, keys, and config" already set up outside VS Code.

WHY THIS WORKS AS AN ANSWER
------------------------------
Installing the extension PACK rather than a single extension matches
the chapter's own framing of all three remote tools (SSH, Dev
Containers, WSL) as one connected topic — the pack is the standard way
most people get all three at once, even if only one is used in any
given project.

Checking specifically whether ssh1's own config populates this list
ties the two courses together concretely, proving Remote-SSH isn't a
separate SSH implementation to learn from scratch — it's a UI layered
directly on top of the SSH knowledge and configuration already built
in that earlier course.
