-# reported
-CSP reports collection for Rails apps
+# Reported
+
+A Rails engine that collects, stores and notifies on Slack about Content Security Policy (CSP) violation reports.
+
+## Features
+
+- Public `/csp-reports` endpoint for browsers to POST CSP violations
+- Stores CSP reports in a database table
+- Tracks notification status with `notified_at` column
+- Optional Slack notifications for CSP violations
+- Easy integration with Rails applications
+
+## Requirements
+
+- Ruby >= 3.2
+- Rails >= 7.1
+- PostgreSQL (for JSONB support)
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'reported'
+```
+
+And then execute:
+
+```bash
+$ bundle install
+```
+
+Or install it yourself as:
+
+```bash
+$ gem install reported
+```
+
+## Setup
+
+1. Run the install generator:
+
+```bash
+$ rails generate reported:install
+```
+
+This will create an initializer at `config/initializers/reported.rb`.
+
+2. Run the migrations:
+
+```bash
+$ rails reported:install:migrations
+$ rails db:migrate
+```
+
+This creates the `reported_reports` table.
+
+The CSP reports endpoint is automatically available at `/csp-reports` (no mounting required).
+
+## Configuration
+
+### Content Security Policy
+
+Configure your application's CSP to send reports to the endpoint. In `config/initializers/content_security_policy.rb`:
+
+```ruby
+Rails.application.config.content_security_policy do |policy|
+  policy.default_src :self, :https
+  policy.script_src  :self, :https
+  # ... your other CSP directives ...
+  
+  # Configure the report URI
+  policy.report_uri "/csp-reports"
+end
+```
+
+### Slack Notifications
+
+To enable Slack notifications, configure the initializer at `config/initializers/reported.rb`:
+
+```ruby
+Reported.configuration do |config|
+  # Enable or disable Slack notifications
+  config.enabled = true
+
+  # Slack webhook URL for notifications
+  config.slack_webhook_url = ENV['REPORTED_SLACK_WEBHOOK_URL']
+end
+```
+
+Get your Slack webhook URL from [Slack API](https://api.slack.com/messaging/webhooks).
+
+Set the webhook URL as an environment variable:
+
+```bash
+REPORTED_SLACK_WEBHOOK_URL=https://hooks.slack.com/services/YOUR/WEBHOOK/URL
+```
+
+## Usage
+
+Once configured, the gem automatically:
+
+1. Receives CSP violation reports at `/reported/csp-reports`
+2. Stores them in the `reported_reports` table
+3. Sends notifications to Slack (if enabled)
+4. Marks reports as notified with the `notified_at` timestamp
+
+### Accessing Reports
+
+You can access reports through the `Reported::Report` model:
+
+```ruby
+# Get all reports
+Reported::Report.all
+
+# Get unnotified reports
+Reported::Report.not_notified
+
+# Get notified reports
+Reported::Report.notified
+
+# Mark a report as notified manually
+report = Reported::Report.first
+report.mark_as_notified!
+```
+
+## Database Schema
+
+The `reported_reports` table includes:
+
+- `document_uri` - The URI of the document where the violation occurred
+- `violated_directive` - The CSP directive that was violated
+- `blocked_uri` - The URI that was blocked
+- `original_policy` - The complete CSP policy
+- `raw_report` - The complete JSON report from the browser
+- `notified_at` - Timestamp of when the report was sent to Slack
+- `created_at` / `updated_at` - Standard timestamps
+
+## License
+
+The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).

+Reported has been installed!
+
+Next steps:
+
+1. Run the migration to create the reports table:
+   
+   rails reported:install:migrations
+   rails db:migrate
+
+2. The CSP reports endpoint is automatically available at /csp-reports
+
+3. Configure your Content Security Policy to send reports to this endpoint:
+   
+   In your config/initializers/content_security_policy.rb:
+   
+   Rails.application.config.content_security_policy do |policy|
+     # ... your CSP directives ...
+     policy.report_uri "/csp-reports"
+   end
+
+4. Configure Slack notifications in config/initializers/reported.rb
+
+5. Set your Slack webhook URL as an environment variable:
+   
+   REPORTED_SLACK_WEBHOOK_URL=https://hooks.slack.com/services/YOUR/WEBHOOK/URL
+
