+## Configuration Validation
 
-- `github-app-id`: The ID of the GitHub app. Need to add the APP to the repository.
-- `name`: repository full name (org or user/repository name)
-- `webhook_ip`: Ip or FQDN where this app will run, this will be added as webhook in the repository setting
-- `github-tokens`: List of admin users token for the repositories
+### Schema Validation
 
-- If `slack_webhook_url` configured for the repository a slack massages will be sent to the configured channel
-  about new releases to pypi, new containers that was pushed
+The webhook server includes comprehensive configuration validation with JSON Schema support for IDE autocompletion and validation.
 
-```yaml
-slack_webhook_url: https://hooks.slack.com/services/<channel>
-````
+#### Validate Configuration Files
 
-If `pypi` configured for the repository a new version will be pushed to pypi on new GitHub release
+```bash
+# Validate your configuration
+uv run webhook_server/tests/test_schema_validator.py config.yaml
 
-- `token`: pypi token with push permissions
-- `tool`: The tool to use to build the package, can be `twine` or `poetry`
+# Validate example configuration
+uv run webhook_server/tests/test_schema_validator.py example.config.yaml
+```
 
-```yaml
-pypi:
-  token: pypi-token
-  tool: twine
+#### Validation Features
+
+- ✅ **Required fields validation** - Ensures all mandatory fields are present
+- ✅ **Type checking** - Validates strings, integers, booleans, arrays, and objects
+- ✅ **Enum validation** - Checks valid values for restricted fields
+- ✅ **Structure validation** - Verifies complex object configurations
+- ✅ **Cross-field validation** - Ensures configuration consistency
+
+#### Running Configuration Tests
+
+```bash
+# Run all configuration schema tests
+uv run pytest webhook_server/tests/test_config_schema.py -v
+
+# Run specific validation test
+uv run pytest webhook_server/tests/test_config_schema.py::TestConfigSchema::test_valid_full_config_loads -v
 ```
 
-if `tox` configured for the repository a tox job will run on each push and new commits

-This tool configure branch protection and set required to be run for each branch to pass before the pull request can be merged
+## Usage
 
-if the repository have the file `.pre-commit-config.yaml` then `pre-commit.ci - pr` will be added, can be excluded by
-set it in `exclude-runs`
+### Starting the Server
 
-- `protected-branches`: array of branches to set protection
-- `branch name`: List of required to be run to set for the branch, when empty set `default-status-checks` as required
-- `include-runs`: Only include those runs as required
-- `exclude-runs`: Exclude those runs from the `default-status-checks`
+```bash
+# Using the container
+podman run -d \
+  --name github-webhook-server \
+  -p 5000:5000 \
+  -v ./data:/home/podman/data:Z \
+  -e WEBHOOK_SECRET=your-secret \
+  quay.io/myakove/github-webhook-server:latest
+
+# From source
+uv run entrypoint.py
+```
 
-By default, we create a `verified_job` run, for each pull request the owner needs to comment `/verified` to mark the pull request as verified
-In order to not add this job set `verified_job` to `false`
+### Webhook Setup
 
-```yaml
-verified_job: false
+1. **Configure GitHub Webhook:**
+
+   - Go to your repository settings
+   - Navigate to Webhooks → Add webhook
+   - Set Payload URL: `https://your-domain.com/webhook_server`
+   - Content type: `application/json`
+   - Secret: Your webhook secret
+   - Events: Select individual events or "Send me everything"
+
+2. **Required Events:**
+   - Push
+   - Pull requests
+   - Issue comments
+   - Check runs
+   - Pull request reviews
+
+## API Reference
+
+### Health Check
+
+```http
+GET /webhook_server/healthcheck
 ```
 
-if `container` is configured for the repository we create `build-container` run that will build the container on each
-pull request push/commit
-Once the pull request is merged, the container will be build and push to the repository
-if `release` is set to `true` a new container will be pushed with the release version as the tag
-if the merged pull request is in any other branch than `main` or `master` the tag will be set to `branch name`, otherwise `tag` will be used
+**Response:**
 
-- `username`: User with push permissions to the repository
-- `password`: The password for the username
-- `repository`: the repository to push the container, for example `quay.io/myakove/github-webhook-server`
-- `tag`: The container tag to use when pushing the container
-- `release`: if `true` a new container will be pushed with the release version as the tag
+```json
+{

+
+## OWNERS File Format
+
+The OWNERS file system provides fine-grained control over code review assignments.
+
+### Root OWNERS File
 
 ```yaml
+# Repository root OWNERS file
 approvers:
-  - root-approver1
-  - root-approver2
+  - senior-dev1
+  - senior-dev2
+  - team-lead
 reviewers:
-  - root-reviewer1
-  - root_reviewer2
+  - developer1
+  - developer2
+  - developer3
 ```
 
-Under folder inside the repositpory (for example `libs`):
+### Directory-specific OWNERS
 
 ```yaml
-root-approvers: False # Not required repository root approvers for this folder
+# Component-specific OWNERS (e.g., backend/OWNERS)
+root-approvers: false # Don't require root approvers for this component
 approvers:
-  - lib-approver1
-  - lib-approver2
+  - backend-lead
+  - senior-backend-dev
 reviewers:
-  - lib-reviewer1
-  - lib-reviewer2
+  - backend-dev1
+  - backend-dev2
+```
+
+### OWNERS File Rules
+
+- **Approvers**: Can approve pull requests for the component
+- **Reviewers**: Can review but approval from approvers still required
+- **root-approvers**: When `false`, root approvers are not required
+- **Inheritance**: Subdirectories inherit parent OWNERS unless overridden
+
+## Security
+
+### IP Allowlist
+
+Configure IP-based access control:
+
+```yaml
+verify-github-ips: true # Restrict to GitHub's IP ranges
+verify-cloudflare-ips: true # Allow Cloudflare IPs (if using CF proxy)
+```
+
+### Webhook Security
+
+```yaml
+webhook-secret: "your-secure-secret" # HMAC-SHA256 signature verification # pragma: allowlist secret
+```
+
+### SSL/TLS Configuration
+
+```yaml
+disable-ssl-warnings:
+  false # Keep SSL warnings in development
+  # Set to true in production if needed
+```
+
+### Token Security
+
+- Use fine-grained personal access tokens when possible
+- Implement token rotation strategy
+- Monitor token usage and rate limits
+- Store tokens securely (environment variables, secrets management)
+
+### Best Practices
+
+1. **Network Security**: Deploy behind reverse proxy with TLS termination
+2. **Container Security**: Run as non-privileged user when possible
+3. **Secrets Management**: Use external secret management systems
+4. **Monitoring**: Enable comprehensive logging and monitoring
+5. **Updates**: Regularly update to latest stable version
+
+## Monitoring
+
+### Health Checks
+
+The server provides built-in health monitoring:
+
+```bash
+curl http://localhost:5000/webhook_server/healthcheck
+```
+
+### Logging
+
+Configure comprehensive logging:
+
+```yaml
+log-level: INFO # DEBUG, INFO, WARNING, ERROR
+log-file: /path/to/webhook-server.log
+```
+
+### Metrics and Observability
+
+- **Request/Response logging** with delivery IDs
+- **Rate limit monitoring** with automatic token switching
+- **Error tracking** with detailed stack traces
+- **Performance metrics** for webhook processing times
+
+### Monitoring Integration
+
+Example Prometheus configuration:
+
+```yaml
+# Add to your monitoring stack
+scrape_configs:
+  - job_name: "github-webhook-server"
+    static_configs:
+      - targets: ["webhook-server:5000"]
+    metrics_path: "/metrics" # If metrics endpoint added
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Webhook Not Receiving Events
+
+1. **Check webhook configuration** in GitHub repository settings
+2. **Verify network connectivity** between GitHub and your server
+3. **Check IP allowlist settings** if enabled
+4. **Validate webhook secret** if configured
+
+#### Repository Not Found Errors
+
+1. **Verify repository name** in configuration matches GitHub
+2. **Check token permissions** for repository access
+3. **Confirm GitHub App installation** on target repositories
+
+#### Rate Limiting Issues
+
+1. **Monitor token usage** in logs
+2. **Add additional tokens** to configuration
+3. **Check token permissions** and validity
+
+#### Container Build Failures
+
+1. **Verify Podman/Docker availability** in container
+2. **Check registry credentials** and permissions
+3. **Review build logs** in check run output
+
+### Debug Mode
+
+Enable detailed logging:
+
+```yaml
+log-level: DEBUG
 ```
 
-### Supported user actions via adding comment
+### Log Analysis
 
-- `/verified`: to verify a pull request
-- `/verified cancel`: to undo verify
-- `/cherry-pick <target_branch_name>`: cherry-pick a merged pull request against a target branch

+* **WIP Status**: Use `/wip` when your PR is not ready for review
+* **Verification**: The verified label is automatically removed on each new commit
+* **Cherry-picking**: Cherry-pick labels are processed when the PR is merged
+* **Container Builds**: Container images are automatically tagged with the PR number
+* **Permission Levels**: Some commands require approver permissions
+* **Auto-verified Users**: Certain users have automatic verification and merge privileges
+
+For more information, please refer to the project documentation or contact the maintainers.
