-# status-endpoint
-A an endpoint for testing polling
+## Simulated Job Status Endpoint
+A endpoint for testing polling
+
+Instructions
+1. Start the Spring Application
+2. In a browser, go to `http://localhost:8080/job/1`
+3. The current status of job #1 is dipslayed in the browser, e.g. **INPROGRESS**
+4. Refresh the browser several times until the status changes. Some jobs are stuck in the INPROGRESS and never complete. This is part of the simulation.
+
+* The endpoint's path is `/job/{id}`, where `id` can be any string. If the string is unrecognized, a new job is created. If `id` is recognized, its current status is returned.
+
+The lifecycle of a job is:
+```
+                                 +----> COMPLETED
+   NOT STARTED +--> IN PROGRESS -|
+                                 +----> FAILED
+```
+
+The lifecycle of a `Job` is determined randomly by the `JobFactory` when the `Job` is created.
