 Rotate outputs from std in or assigned file
 
 Usage:
+
 ```shell
 command | rotate-puts
 ```
 
 Use `mkfifo`:
+
 ```shell
 mkfido test-fifo
 rotate-puts --file test-fifo
 command > test-fifo
 ```
+
+Run as daemon:
+
+```shell
+rotate-put --file test-fifo --daemon --iden test [--continue-read]
+```
+
+For nginx:
+
+```shell
+mkfifo access.log
+mkfifo error.log
+```
+
+```shell
+./rotate-puts --daemon --file access.log --prefix nginx_access --continue-read --ident nginx_access
+./rotate-puts --daemon --file error.log --prefix nginx_error --continue-read --ident nginx_error
