Start with the questions people need to answer
A documentation index is a short guide to where project information lives. It does not need to contain every detail itself. Its job is to help someone move from a question—“What did we agree to deliver?” or “Where is the latest design?”—to the right document with minimal guesswork.
Before creating headings, list the questions people regularly ask during the project. A freelancer might need quick access to the approved brief, client feedback and handoff files. A student group might look for assignment requirements, research notes and who is completing each task. A small team may also need decision records, technical instructions and review status. Use those needs to shape the index rather than copying a folder structure that only its creator understands.
Give the index a simple, predictable structure
Put the index in a place collaborators already use, such as the main project workspace or shared folder, and give it an unmistakable name like “Project Index.” Near the top, include a one- or two-sentence description of the project, the current phase and the person to contact when a link or description is unclear. If the project uses several tools, the index can serve as their shared entry point.
Group links by purpose. Useful sections might include “Start here” for the brief and scope, “Plan and progress” for milestones and task boards, “Working materials” for drafts and assets, “Decisions and feedback” for approvals and changes, and “Delivery” for final files and handoff instructions. Keep the number of top-level groups small enough to scan. When a section grows crowded, add a short subheading or move detailed lists to a linked page.
Avoid using only file names as labels. “Approved project brief — goals, audience and deliverables” tells a reader more than “Brief_v4.” For a decision log, say what kinds of decisions it records and whether it is still active. A brief description beside each link helps people choose the right destination before opening multiple documents.
Make status and ownership visible
An index becomes confusing when drafts, approved materials and archived files look equally important. Mark key links with plain-language status labels such as “working draft,” “approved” or “superseded.” Point to one preferred location for the latest version, even if older versions remain available elsewhere. If two documents appear to conflict, readers should know which one governs the current work.
For important entries, add an owner or maintainer and, where useful, a note about when the document should be revisited. The owner is not necessarily the only author; they are the person who can clarify its purpose and update its index entry. This can be lightweight: “Feedback log — active; maintained by Maya” is often enough. If access is restricted, label the link accordingly rather than leaving teammates to assume it is broken.
Test the index with a real task
Once the first version is ready, ask someone who did not build it to find three things: the agreed deliverables, the latest work in progress and the next review step. Watch for hesitation. If they choose an outdated link or have to search messages for context, adjust the label, grouping or destination. This small test is more useful than trying to design a perfect hierarchy in advance.
Consider how someone joins the project halfway through. Can they understand the purpose of each section without a verbal tour? Can they distinguish background material from instructions they must follow now? An index works best when it offers a clear route into the project while letting detailed documents remain in their appropriate homes.
Keep it useful through delivery and handoff
Treat the index as part of the project routine, not a page created once and forgotten. When a new document becomes essential, add it. When a draft is replaced, update the preferred link or mark the old entry as superseded. A quick review before a team check-in or client review can catch broken links and unclear status labels while the work is still fresh.
At delivery, shift the index toward what the next reader needs. Put final outputs, usage notes and any remaining open questions near the top, while retaining links to decisions and working history for context. For a portfolio project, you may create a separate, shareable version that links only to material you have permission to show. The goal is not to expose the entire workspace; it is to make the project’s relevant story and final materials easy to navigate.
