Description

This PR improves the contributor onboarding and development documentation for GitHub Tracker.

The following improvements have been made:

  • Improved local setup and installation instructions
  • Corrected and clarified frontend and backend development workflows
  • Added clear backend development and production commands
  • Added Docker development and production workflow documentation
  • Improved project structure documentation
  • Added environment configuration guidance
  • Added testing, linting, and build instructions
  • Added troubleshooting guidance for common setup issues
  • Improved the first-time contributor workflow
  • Added docs/DEVELOPMENT.md as a dedicated development guide
  • Improved Markdown formatting, readability, and navigation across the documentation

Files updated/added:

  • README.md
  • CONTRIBUTING.md
  • docs/DEVELOPMENT.md

No application source code or functionality was changed.


How Has This Been Tested?

  • Reviewed the documented setup and development commands against the project's package.json, backend/package.json, and Docker configuration.
  • Verified that the documented frontend command is npm run dev.
  • Verified that the backend development command is npm run dev.
  • Verified that the backend production/start command is npm start.
  • Verified the documented Docker commands against docker-compose.yml.
  • Documentation-only changes were made, so no application logic was modified.

Review Change Stack

Warning

Review limit reached

@SriHarshitha137, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 16 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The pull request replaces the README and contribution guide and adds a development guide. The documentation covers project setup, local and Docker workflows, testing, validation, contribution procedures, security, and troubleshooting.

Changes

Documentation and onboarding

Layer / File(s) Summary
Project overview and setup
README.md
The README now documents the project structure, prerequisites, environment configuration, local setup, and service startup.
Development workflows and validation
README.md, docs/DEVELOPMENT.md
The documentation covers Docker workflows, ports, testing, linting, builds, architecture, and pre-pull-request checks.
Contribution procedures
CONTRIBUTING.md, README.md
The guides document branching, commits, pull requests, issue reporting, security, troubleshooting, and contributor standards.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f7d06

The documentation update still has concrete setup gaps around MongoDB connectivity, required environment variables, and several contributor commands. These omissions can prevent new contributors from starting, testing, or submitting changes successfully, so the PR is not merge-ready until the instructions are clarified.

Keep Option 1 as one complete local workflow.

The local workflow installs backend dependencies in Lines 76-81, but the backend start commands appear in a separate repeated section in Lines 83-114. Move npm run dev and npm start into Option 1, then remove the duplicate backend setup.

Inline comments:
In `@CONTRIBUTING.md`:
- Around line 162-169: Update the backend setup instructions in CONTRIBUTING.md
to state the exact start command from backend/package.json, including that it
must be run from the backend directory, or link directly to docs/DEVELOPMENT.md
if it is the canonical source.
- Around line 72-75: Update the CONTRIBUTING setup commands so the clone
destination matches the subsequent cd github_tracker command: either provide
github_tracker as the explicit git clone destination or change the cd command to
the directory produced by the clone.
- Around line 276-282: Update the contributor instructions to replace the
blanket git add . command with guidance to stage only intended files, then
inspect the staged diff before committing. Keep the existing commit and push
workflow unchanged.
- Line 284: Update the pull-request guidance text to explicitly identify main as
the target branch, replacing the generic “project's main development branch”
wording while preserving the rest of the instruction.
- Around line 215-219: Update the “Frontend tests” command in CONTRIBUTING.md to
use npm test -- --run, ensuring Vitest performs one non-interactive test run and
exits instead of starting watch mode.
- Around line 91-102: Update the “Configure environment variables” section in
CONTRIBUTING.md with exact steps to create or copy safe example files for .env
and backend/.env, and document the required VITE_BACKEND_URL, MONGO_URI, and
SESSION_SECRET values before running npm run docker:dev. Keep real secrets
excluded from version control.

Apply the same fix in `@README.md` around lines 163 - 176: The development guide
should repeat the same complete environment configuration.

In `@README.md`:
- Around line 218-243: Document the external MongoDB requirement consistently:
in README.md lines 218-243 and 253-280, and docs/DEVELOPMENT.md lines 121-141
and 217-241, explain that Compose does not provide MongoDB and specify the
supported database location plus container-to-host or external-network
connectivity requirements.

Apply the same fix in `@CONTRIBUTING.md` around lines 173 - 187: The contributor
guide currently lists MongoDB without explaining where it runs for Docker
development.

Provide complete first-run environment setup before instructing contributors to run npm run docker:dev. Show safe example or copy/create steps for .env and backend/.env, and list the required VITE_BACKEND_URL, MONGO_URI, and SESSION_SECRET variables. Keep the same actionable guidance in README.md and docs/DEVELOPMENT.md.

Do not recommend blanket staging.

git add . stages every unignored file. This can include generated files or accidentally created secrets. Stage intended files and inspect the staged diff before committing.

Proposed fix
- git add .
+ git add -p
+ git diff --cached

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

## Docker Development

Docker Compose provides a complete development setup containing frontend and backend services.

Make sure Docker Desktop is installed and running.

From the project root:

```bash
docker compose --profile dev up --build
```

The corresponding npm shortcut is:

```bash
npm run docker:dev
```

### Development services

| Service | Port | Purpose |
| -------- | ---: | ----------------------- |
| Frontend | 5173 | Vite development server |
| Backend | 5000 | Express backend |

The development containers mount the local source directories, allowing changes to be reflected during development.

Document the external MongoDB dependency consistently across all Docker workflows. The Compose setup does not include a MongoDB service, so contributors need explicit guidance on where MongoDB runs and how the containerized services reach it. Update the Docker development and production sections here, the Docker option and workflow in docs/DEVELOPMENT.md, and the Docker development section in CONTRIBUTING.md.
