+
+Persistent Distributed Job Priority Queue for [golang](http://golang.org/) powered by [Disque](https://github.com/antirez/disque).
+
+- **Persistent** - Jobs can be persisted on disk.
+- **Distributed** - Multiple producers, multiple consumers.
+- **Job Priority Queue** - Consumers dequeue "high" priority jobs first.
+- **Tolerant to consumer failures** - Jobs are requeued automatically if not ACKed within the Retry Timeout.

+
+## Disque
+
+Install & run [Disque](https://github.com/antirez/disque) server.
+
+*TODO: Explain how to enable disk persistence.*
+
+## Producers
+
+```go
+// Connect to Disque server.
+jobs, _ := pjobs.Connect("127.0.0.1:7711")
+
+// Enqueue job (data + priority).
+job, _ := jobs.Enqueue("data", "low")
+job, _ := jobs.Enqueue("data", "high")
+```
+
+## Consumers
+
+```go
+// Connect to Disque server.
+jobs, _ := pjobs.Connect("127.0.0.1:7711")
+
+// Dequeue job ("high" priority jobs first).
+job, _ := jobs.Dequeue("high", "low")
+
+// Do some hard work with job.Data.
+
+// Acknowledge that job was processed successfully.
+jobs.Ack(job)
