+# Dependabot Configuration for Go Modules
+
+This repository is configured to use Dependabot for automated dependency updates with `go mod tidy` support.
+
+## Configuration Files
+
+1. `.github/dependabot.yml` - Configures Dependabot to check for Go module updates weekly
+2. `.github/workflows/dependabot-go-mod-tidy.yml` - GitHub Actions workflow that runs `go mod tidy` on Dependabot PRs
+
+## How It Works
+
+1. Dependabot creates PRs to update Go dependencies according to the schedule in `dependabot.yml`
+2. When a PR is created that modifies `go.mod` or `go.sum`, the workflow is triggered
+3. The workflow checks if the PR was created by Dependabot
+4. If so, it runs `go mod tidy` and commits any changes back to the PR
+
+## Required Repository Settings
+
+For the workflow to function properly, you need to configure the repository to allow Dependabot to trigger workflows with write permissions:
+
+1. Go to the repository on GitHub
+2. Navigate to Settings > Code and automation > Actions > General
+3. Scroll down to "Workflow permissions"
+4. Enable "Read and write permissions"
+5. Check "Allow GitHub Actions to create and approve pull requests"
+6. Save changes
+
+Additionally, you need to configure Dependabot to have write access to PRs:
+
+1. Go to the repository on GitHub
+2. Navigate to Settings > Code and automation > Actions > General
+3. Scroll down to "Workflow permissions from pull requests"
+4. Select "Allow Dependabot to run workflows"
+5. Save changes
+
+## Troubleshooting
+
+If the workflow isn't running or isn't able to commit changes:
+
+1. Check that the repository settings are configured as described above
+2. Verify that the PR was created by Dependabot
+3. Check the workflow run logs for any errors
