@@ -6,6 +6,24 @@ handed to the agent. A how-to guide never retells an agent's procedure: the step
 live in `instructions/`, and a guide here says what to prepare, what to ask for and where the
 agent stops.
 
-Nothing is here yet. Until the guides are written, the task-shaped parts of
-[README.md](../../README.md), [INSTALL.md](../../INSTALL.md),
-[INSTALL-MCP.md](../../INSTALL-MCP.md) and [EVALS.md](../../EVALS.md) still carry this material.
+Working with the wiki:
+
+- [Ingest a source](ingest-a-source.md) - a file, a folder, a web page, or a document submitted
+  through the MCP server
+- [Capture documentation from a git repository](capture-repository-docs.md) - and keep it current
+- [Export guidelines to captured repositories](export-guidelines.md)
+- [Query the wiki](query-the-wiki.md) - asking, and searching yourself
+- [Maintain the wiki](maintain-the-wiki.md) - lint, provenance, and the gates on the way to a publish
+- [Run the weekly review](run-the-weekly-review.md) - commitments in a task tracker against the
+  project pages
+- [Browse the wiki in Obsidian](browse-with-obsidian.md) - and how pages are named
+
+Running the instance:
+
+- [Update an instance](update-an-instance.md) - to a newer release of the stack
+- [Troubleshoot an instance](troubleshoot.md)
+- [Set up the MCP read server](set-up-the-mcp-server.md) - for a consumer that is not a terminal
+  on this machine
+- [Trace and score agent sessions](trace-and-score-sessions.md)
+
+Installing a new instance is [INSTALL.md](../../INSTALL.md) at the repository root.
