+=======
+
+persist is a fast and simple asynchronous process manager.
+
+Example
+-------
+
+```bash
+# start managing a new process.
+persist start --name http-server -- serve .
+
+# list managed processes.
+persist ls
+
+# stop the running process.
+persist stop http-server
+
+# restart the process.
+persist restart http-server
+
+# stop managing the process.
+persist delete http-server
+
+# stop the background deamon.
+persist daemon kill

+persist
+=======
+
+persist is a fast and simple asynchronous process manager.
+
+Example
+-------
+
+```bash
+# start managing a new process.
+persist start --name http-server -- serve .
+
+# list managed processes.
+persist ls
+
+# stop the running process.
+persist stop http-server
+
+# restart the process.
+persist restart http-server
+
+# stop managing the process.
+persist delete http-server
+
+# stop the background deamon.
+persist daemon kill
+```
