+# Dependabot Workflow
+
+## Overview
+
+Dependabot is a GitHub-native tool that automatically opens pull requests to keep dependencies up to date. Its configuration settings are located in `.github/dependabot.yml`, and runs weekly.
+
+## What Dependabot Updates
+
+- **Node.js dependencies**: Dependencies declared in `package.json` and the lockfile `yarn.lock`
+- **Docker dependencies**: Updates base image tags referenced by Dockerfiles (e.g. the one in `apps/backend`)
+- **GitHub Actions**: Updates action versions used in workflows in `.github/workflows`
+
+## Schedule and Ownership
+
+Dependabot creates PRs on a **weekly** basis, and automatically assigns the PRs to `aaronashby` and `thaninbew`
+
+## How to Review Dependabot PRs
+
+- Skim the PR title, release notes, and commits
+- Check the diff
+  - Dependency updates often change `package.json` + `yarn.lock` (or only `yarn.lock`).
+  - Docker updates typically change a `FROM …` line.
+  - Actions updates usually change `uses: …@vX` pins in workflows.
+
+## Merging Guidelines (suggested)
+
+- **Patch/minor updates**: usually safe to merge once CI passes.
+- **Major updates**: prefer a quick manual smoke test and a scan for breaking changes.
+- **Lockfile-only updates**: merge if CI passes (these happen due to dependency resolution changes).
+
+## Common Tweaks (edit `.github/dependabot.yml`)
+
+- **Add a separate Docker entry for root compose files**
+  - Dependabot currently only scans Docker in `/apps/backend`. If you want it to update `docker-compose.dev.yml` at the repo root, add another docker update with `directory: "/"`.
+- **Limit PR volume**
+  - Add `open-pull-requests-limit: <number>` to an update block.
+- **Ignore versions**
+  - Use `ignore:` to skip major versions or specific packages temporarily.
+- **Group updates**
+  - Use `groups:` to bundle related packages (e.g., React, NestJS, Nx) into fewer PRs.
+
+## Troubleshooting
+- **CI fails after a bump**
+  - Check the package’s changelog/release notes and revert/ignore if needed.
+  - If it’s a tooling bump (Nx/Vite/ESLint/TypeScript), failures often come from peer dependency changes or config deprecations.
+- **Dependabot isn’t opening PRs**
+  - Confirm `.github/dependabot.yml` is on the default branch and syntactically valid.
+  - Check the repo’s Dependabot alerts/PRs in GitHub for run history and errors.
