+# Runners Overview
+
+Runners are the execution layer in the Horus architecture. They receive jobs from the Supervisor via Redis queues and execute the actual workload.
+
+## Architecture
+
+```
+Supervisor → Redis Queue → Runner → Execute Job → Return Result
+```
+
+## Available Runners
+
+Horus provides three specialized runners:
+
+### 1. **Hero Runner**
+Executes heroscripts using the Hero CLI ecosystem.
+
+**Use Cases:**
+- Running Hero automation tasks
+- Executing heroscripts from job payloads
+- Integration with Hero CLI tools
+
+**Binary:** `herorunner`
+
+[→ Hero Runner Documentation](./hero.md)
+
+### 2. **SAL Runner**
+System Abstraction Layer runner for system-level operations.
+
+**Use Cases:**
+- OS operations (file, process, network)
+- Infrastructure management (Kubernetes, VMs)
+- Cloud provider operations (Hetzner)
+- Database operations (Redis, Postgres)
+
+**Binary:** `runner_sal`
+
+[→ SAL Runner Documentation](./sal.md)
+
+### 3. **Osiris Runner**
+Database-backed runner for data storage and retrieval using Rhai scripts.
+
+**Use Cases:**
+- Structured data storage
+- Model-based data operations
+- Rhai script execution with database access
+
+**Binary:** `runner_osiris`
+
+[→ Osiris Runner Documentation](./osiris.md)
+
+## Common Features
+
+All runners implement the `Runner` trait and provide:
+
+- **Job Execution**: Process jobs from Redis queues
+- **Signature Verification**: Verify job signatures before execution
+- **Timeout Support**: Respect job timeout settings
+- **Environment Variables**: Pass environment variables to jobs
+- **Error Handling**: Comprehensive error reporting
+- **Logging**: Structured logging for debugging
+
+## Runner Protocol
+
+Runners communicate with the Supervisor using a Redis-based protocol:
+
+1. **Job Queue**: Supervisor pushes jobs to `runner:{runner_id}:jobs`
+2. **Job Processing**: Runner pops job, validates signature, executes
+3. **Result Storage**: Runner stores result in `job:{job_id}:result`
+4. **Status Updates**: Runner updates job status throughout execution
+
+## Starting a Runner
+
+```bash
+# Hero Runner
+herorunner <runner_id> [--redis-url <url>]
+
+# SAL Runner
+runner_sal <runner_id> [--redis-url <url>]
+
+# Osiris Runner
+runner_osiris <runner_id> [--redis-url <url>]
+```
+
+## Configuration
+
+All runners accept:
+- `runner_id`: Unique identifier for the runner (required)
+- `--redis-url`: Redis connection URL (default: `redis://localhost:6379`)
+
+## Security
+
+- Jobs must be cryptographically signed
+- Runners verify signatures before execution
+- Untrusted jobs are rejected
+- Environment variables should not contain sensitive data in production
