Write a README That Helps Future You Ship

You opened the repo after two weeks, and the only file that explains anything is a comment in main. You stare at that comment, which only says “TODO: fix auth flow,” and you can’t remember if you set the local dev server to use port 3000 or 5173, if you seeded the test database with dummy users, or even what the original half-finished feature was supposed to do. This is the exact pain point an intentional, short README solves — no fluff, just the exact information you need to pick up work again in 10 minutes instead of 2 hours. The best README for small solo projects is not a 10-page essay on architecture, it’s a 5-section cheat sheet that answers every question you’ll have when you return to code after time away. Use this standard template for every project to cut down on rework and keep shipping fast:

Run command a stranger can copy

The goal of this section is to eliminate all decision fatigue when you spin up the project again. You should not have to dig through `package.json`, shell history, or random config files to remember how to start the dev server. The command must be fully copy-pasteable, with no unwritten steps you only have stored in your head. Example measurement: If your run command takes more than 3 lines to explain, you’re overcomplicating it, and should consolidate steps into a single bash or npm script instead. Test the command once on a fresh clone of your repo to catch any hidden local setup you forgot to document, like a global dependency you installed 6 months ago that’s not listed in the pre-requisites. If you have operating system-specific steps, note them clearly below the main command, for example: “Windows users: replace `cp` with `copy` in the command above to copy the env file correctly.”

Test command you keep next to run

Testing is useless if you avoid running tests because you can’t remember the right command or the full suite takes too long to run locally. This section sits directly below the run command so you don’t have to search for it, and separates local test commands from CI-only test commands that run slow, resource-heavy E2E or integration tests. Illustrative example: If your full test suite takes 12 minutes to run, your local test command should skip the 9 minutes of E2E and integration tests so you get feedback in 3 minutes or less as you write code. Add a note for how to run a single test file for focused work, since 9 out of 10 times you return to a project, you’re only working on one small feature and don’t need to run the entire test suite every time you make a change. You can also note common test failure fixes here, like “If snapshot tests fail, run `npm run test:update-snapshots` to reset them after intentional UI changes.”

Data paths that must not be committed

This section is not just a repeat of your `.gitignore` file, because `.gitignore` only tells Git what not to push — it doesn’t tell you how to recover those files if you delete them accidentally, or what they’re for. List every file path and glob pattern that contains secrets, local user data, temporary build cache, or database dumps that should never end up in your remote repo. Include clear instructions for how to regenerate any of these files if they’re missing, so you don’t get stuck trying to find an old database dump you saved to your Downloads folder 3 weeks prior. Example measurement: If you’ve ever had to reset an API key because you accidentally pushed it to a public repo, this section will save you at least 15 minutes of cleanup next time. You can also add notes for what to do if you do commit a secret by mistake, like “If you accidentally push the `.env` file, rotate all API keys in the file immediately and force-push a delete for that file from Git history.”

Limits you admit so future-you stops guessing

Scope creep is the number one reason small solo projects never ship, and the biggest cause of scope creep is future you forgetting what you were and were not planning to build in the current iteration. When you’re deep in work on a project, you know exactly what limits you’ve set for the first version, but those limits disappear from your memory after even a week away from the code. Use this section to list all hard constraints, technical limits, and intentional feature cuts for the current build, so you don’t waste days building functionality you didn’t actually need to ship the core product. Limits can be technical (max file upload size 10MB), feature-related (no multi-user admin access in this version), or even time-related (no more than 4 hours spent on styling for this launch). Every time you’re tempted to add a new feature that’s not part of the original plan, check this section first to confirm you’re not derailing your launch timeline.

Next-slice line you update on every Friday

Most project to-do lists are long, vague, and overwhelming, so when you return to a project after time away, you spend 30 minutes or more trying to figure out where to start, then get distracted and close the repo again. The next-slice line solves this problem by giving you one single, specific, actionable task to start on immediately, with zero decision fatigue. You update this line every Friday before you step away from the project for the week, so it’s always the exact next thing you were planning to work on when you left. Avoid vague entries like “fix auth” — instead, write specific, scoped tasks like “Add password reset email flow using Resend; test against Gmail and ProtonMail inboxes first.” Once you finish that task, replace it with the next single task, so you never have a long list of to-dos to sort through when you come back to code.

Open your most recent unfinished project repo right now, add a 5-line README using the template table above as a guide, and update the next-slice line to the exact task you were working on when you last stepped away. It will take you less than 5 minutes, and save you hours of frustration the next time you open the repo.
