+# GitHub Actions
+
+This document describes the CI/CD workflows for OSPOS.
+
+## Build and Release Workflow (`.github/workflows/build-release.yml`)
+
+### Build Process
+- Setup PHP 8.2 with required extensions
+- Setup Node.js 20
+- Install composer dependencies
+- Install npm dependencies
+- Build frontend assets with Gulp
+
+### Docker Images
+- Build and push `opensourcepos` Docker image for multiple architectures (linux/amd64, linux/arm64)
+- On master: tagged with version and `latest`
+- On other branches: tagged with version only
+- Pushed to Docker Hub
+
+### Releases
+- Create distribution archives (tar.gz, zip)
+- Create/update GitHub "unstable" release on master branch only
+
+## Required Secrets
+
+To use this workflow, you need to add the following secrets to your repository:
+
+1. **DOCKER_USERNAME** - Docker Hub username for pushing images
+2. **DOCKER_PASSWORD** - Docker Hub password/token for pushing images
+
+### How to add secrets
+
+1. Go to your repository on GitHub
+2. Click **Settings** → **Secrets and variables** → **Actions**
+3. Click **New repository secret**
+4. Add `DOCKER_USERNAME` and `DOCKER_PASSWORD`
+
+The `GITHUB_TOKEN` is automatically provided by GitHub Actions.
+
+## Workflow Triggers
+
+- **Push to master** - Runs build, Docker push (with `latest` tag), and release
+- **Push to other branches** - Runs build and Docker push (version tag only)
+- **Push tags** - Runs build and Docker push (version tag only)
+- **Pull requests** - Runs build only (PHPUnit tests run in parallel via phpunit.yml)
+
+## Existing Workflows
+
+This repository also has these workflows:
+- `.github/workflows/main.yml` - PHP linting with PHP-CS-Fixer
+- `.github/workflows/phpunit.yml` - PHPUnit tests (runs on all PHP versions 8.1-8.4)
+- `.github/workflows/php-linter.yml` - PHP linting
+
+## Testing
+
+PHPUnit tests are run separately via `.github/workflows/phpunit.yml` on every push and pull request, testing against PHP 8.1, 8.2, 8.3, and 8.4.
+
+To test the build workflow:
+1. Add the required secrets
+2. Push to master or create a PR
+3. Monitor the Actions tab in GitHub

+# Agent Instructions
+
+This document provides guidance for AI agents working on the Open Source Point of Sale (OSPOS) codebase.
+
+## Code Style
+
+- Follow PHP CodeIgniter 4 coding standards
+- Run PHP-CS-Fixer before committing: `vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.no-header.php`
+- Write PHP 8.1+ compatible code with proper type declarations
+- Use PSR-12 naming conventions: `camelCase` for variables and functions, `PascalCase` for classes, `UPPER_CASE` for constants
+
+## Development
+
+- Create a new git worktree for each issue, based on the latest state of `origin/master`
+- Commit fixes to the worktree and push to the remote
+
+## Testing
+
+- Run PHPUnit tests: `composer test`
+- Tests must pass before submitting changes
+
+## Build
+
+- Install dependencies: `composer install && npm install`
+- Build assets: `npm run build` or `gulp`
+
+## Conventions
+
+- Controllers go in `app/Controllers/`
+- Models go in `app/Models/`
+- Views go in `app/Views/`
+- Database migrations in `app/Database/Migrations/`
+- Use CodeIgniter 4 framework patterns and helpers
+- Sanitize user input; escape output using `esc()` helper
+
+## Security
+
+- Never commit secrets, credentials, or `.env` files
+- Use parameterized queries to prevent SQL injection
+- Validate and sanitize all user input

 ## Server Requirements
 
-- PHP version `8.1` to `8.4` are supported, PHP version `≤7.4` is NOT supported. Please note that PHP needs to have the extensions `php-json`, `php-gd`, `php-bcmath`, `php-intl`, `php-openssl`, `php-mbstring`, `php-curl` and `php-xml` installed and enabled. An unstable master build can be downloaded in the releases section.
+- PHP version `8.2` to `8.4` are supported, PHP version `≤ 8.1` is NOT supported.

An unstable master build can be downloaded in the releases section.
 - MySQL `5.7` is supported, also MariaDB replacement `10.x` is supported and might offer better performance.
 - Apache `2.4` is supported. Nginx should work fine too, see [wiki page here](https://github.com/opensourcepos/opensourcepos/wiki/Local-Deployment-using-LEMP).
 - Raspberry PI based installations proved to work, see [wiki page here](<https://github.com/opensourcepos/opensourcepos/wiki/Installing-on-Raspberry-PI---Orange-PI-(Headless-OSPOS)>).
 - For Windows based installations please read [the wiki](https://github.com/opensourcepos/opensourcepos/wiki). There are closed issues about this subject, as this topic has been covered a lot.
 
+## Security Configuration
+
+### Allowed Hostnames (REQUIRED for Production)
+
+⚠️ **CRITICAL**: OpenSourcePOS validates the Host header to prevent Host Header Injection attacks (GHSA-jchf-7hr6-h4f3). **You MUST configure `app.allowedHostnames` for production deployments. If not configured, the application will fail to start.**
+
+**Add to your `.env` file:**
+
+```bash
+# Comma-separated list of allowed hostnames (no protocols or ports)
+app.allowedHostnames = 'yourdomain.com,www.yourdomain.com'
+```
+
+**For local development:**
+
+```bash
+app.allowedHostnames = 'localhost'
+```
+
+**If you see this error at startup:**
+
+```text
+RuntimeException: Security: allowedHostnames is not configured.
+```
+
+**Solution**: Add `app.allowedHostnames` to your `.env` file with your domain(s).
+
+**Why this matters:**
+- Prevents Host Header Injection attacks (GHSA-jchf-7hr6-h4f3)
+- Ensures URLs are generated with the correct domain
+- Security advisory: https://github.com/opensourcepos/opensourcepos/security/advisories/GHSA-jchf-7hr6-h4f3
+- Fixes issue #4480: .env configuration now works via comma-separated values
+
+### HTTPS Behind Proxy
+
+If your installation is behind a proxy with SSL offloading, set:
+```
+FORCE_HTTPS = true
+```
+

To build the project from a source commit point instead of from an official release check out [Building OSPOS](BUILD.md). Otherwise, continue with the following steps.
+First of all, if you're seeing the message `system folder missing` after launching your browser, that most likely means you have cloned the repository and have not built the project. To build the project from a source commit point instead of from an official release check out [Building OSPOS](BUILD.md). Otherwise, continue with the following steps.
 
 1. Download the a [pre-release for a specific branch](https://github.com/opensourcepos/opensourcepos/releases) or the latest stable [from GitHub here](https://github.com/opensourcepos/opensourcepos/releases). A repository clone will not work unless know how to build the project.
 2. Create/locate a new MySQL database to install Open Source Point of Sale into.
-3. Execute the file `app/Database/database.sql` to create the tables needed.
-4. Unzip and upload Open Source Point of Sale files to the web-server.
-5. Open `.env` file and modify credentials to connect to your database if needed. (First copy .env.example to .env and update)
+3. Unzip and upload Open Source Point of Sale files to the web-server.
+4. If `.env` does not exist, copy `.env.example` to `.env`.
+5. Open `.env` and modify credentials to connect to your database if needed.
+6. The database schema will be automatically created when you first access the application. Migrations run automatically on fresh installs.
 7. Go to your install `public` dir via the browser.
 8. Log in using
    - Username: admin
    - Password: pointofsale
 9. If everything works, then set the `CI_ENVIRONMENT` variable to `production` in the .env file
-9. Enjoy!
-10. Oops, an issue? Please make sure you read the FAQ, wiki page, and you checked open and closed issues on GitHub. PHP `display_errors` is disabled by default. Create an` app/Config/.env` file from the `.env.example` to enable it in a development environment.
