An AI project can produce an impressive answer while leaving its engineering unexplained. A visitor sees a chat window, a list of frameworks and a claim that the application is accurate. They still cannot tell which documents it used, how to run it, or what happens when its answer is unsupported.
Your README is where that uncertainty should begin to disappear. Treat it as a short argument supported by inspectable work: here is the problem, here is the system, and here is the evidence behind each claim.
GitHub describes a README as a place to explain a project's purpose, usefulness, setup and maintainers. For an AI portfolio, add the evidence needed to judge model-dependent behaviour. GitHub's README guidance
Start with a boundary someone can understand
Consider an illustrative project: an assistant that answers questions from a small collection of public appliance manuals.
Its opening could explain that it finds relevant manual sections, writes an answer with references, and reports insufficient evidence when the collection does not answer the question. It should also state that it cannot inspect the appliance or verify a repair.
That description gives a reviewer something concrete to assess. Include who uses it, the accepted inputs, the output and the excluded uses. Identify whether the corpus is public, licensed or synthetic. A domain boundary also helps you notice when an attractive feature would demand evidence you do not have.
Make one complete path reproducible
Reproducibility means another person can follow your instructions and observe the behaviour you describe. It does not require a reviewer to recreate your entire development environment from memory.
List the supported runtime, dependency installation, configuration and required external services. Supply example configuration containing placeholders, never credentials. Explain whether the initial run downloads data, builds an index or makes paid API calls. Separate preparation steps from normal startup.
If you provide an offline fixture mode, say exactly what it replaces. Recorded answers can demonstrate interface behaviour and error handling; they cannot measure a live model's current quality. Label that distinction next to the startup instructions.
Before sharing, follow the documented route in a clean environment. Record the date, environment and checks you actually completed. If a step failed, fix it or describe the limitation. Do not add a successful verification badge without a corresponding check.
Show the system through one request
A small request-flow diagram is usually more useful than a wall of logos. For the manual assistant, describe the path from question to retrieval, context assembly, answer generation and source display. Then show the separate path that turns documents into searchable chunks.
Define unfamiliar terms beside their first use. A chunk is a section of source material prepared for search. An embedding is a numerical representation used to compare content. Explain which component stores source identities so the answer can point back to the right manual.
Microsoft's RAG architecture guide separates document preparation from the application request flow. That separation is a useful starting point for explaining your own design. RAG design and evaluation
Put evidence beside claims
Replace an unsupported adjective with a question a reviewer can investigate. The following table is an editorial checklist, not a report of achieved results.
| Claim you want to make | Evidence to provide |
|---|---|
| Answers are grounded | Labelled questions, retrieved passages and checks that answer statements follow from them |
| Search improved | Baseline and candidate results on the same question set |
| The service handles failures | A reproducible timeout or unavailable-dependency case and its expected response |
| The project is reproducible | Setup instructions and a record of a clean-environment check |
| Costs are understood | Measurement method, included operations, provider assumptions and remaining uncertainty |
Keep the headline report short and link to detailed evidence in the repository. State the number of evaluated questions and how you selected them. A handpicked demonstration set is useful for explanation, but its score should not be presented as representative user performance.
For RAG, inspect retrieval and answers separately. Finding a relevant passage and using it correctly are different behaviours; a single score can conceal which one failed.
Explain a failure before someone discovers it
Choose a failure you actually observed. If you have not run the project yet, identify the planned test instead of inventing a debugging story.
An illustrative failure might involve two manuals with similar model names. The system retrieves the wrong model's instructions and writes a fluent answer. The useful write-up identifies the affected query, the retrieved source and the change being investigated, such as filtering by model identifier. It does not merely say that the prompt needed improvement.
Include operational failures too: unavailable services, malformed files, empty retrieval and excessive request size. Google's machine-learning guidance stresses infrastructure testing and monitoring for failures that may otherwise remain unnoticed. Rules of Machine Learning
State security choices without promising complete safety
Explain which inputs are untrusted, where credentials live, what gets logged and whether users share a search index. Document any authorization boundaries before implying that the system supports private documents.
For a document assistant, a useful test checks whether instructions embedded in a source document can redirect the application. Another checks whether diagnostic logs expose sensitive input. Publish test descriptions and safe fixtures, not private documents or real credentials.
OWASP identifies prompt injection, sensitive-information disclosure and vector-related weaknesses among relevant risks. Passing a few tests addresses specific cases; it does not establish that an application is secure in every setting. OWASP GenAI risks
Close with a decision, a limitation and a next experiment
A strong final section explains one design decision, one unresolved limitation and the next test you would run. Perhaps you kept a simpler search baseline because you have not yet demonstrated a benefit from additional components. That is a useful engineering position when the evidence supports it.
Read the README from top to bottom once more. Can a visitor find the purpose, run a meaningful path and inspect the evidence without asking you to fill in missing steps? If so, the document is doing practical work for your portfolio.
