+# Sample Python Application for `piku`
+
+This is a simple Python app that demonstrates:
+
+- HTTP port selection via the `PORT` variable (set in `ENV`)
+* An independent worker process (that is auto-restarted upon exit) 
+* Another independent worker with a built-in scheduler
+
+To publish this app to `piku`, clone the repository and run the following commands:
+
+```bash
+git remote add piku piku@your_server:sample_python_app
+git add .
+git commit -a -m "initial commit"
+git push piku master
+```
