+When cmd-ctrld runs, user should provide one certificate and create one account for bindctl. 
+
+
+1. Get a certificate
+
+cmd-ctrld is a https server, so a certificate should be acquired for the SSL-encrypted connection services it provides.
+There are many ways of acquiring appropriate cetificates, such as buying one from a certification authority. Another common practice is to generate a self-signed certificate. The simplest way to do this is with the OpenSSL package, using something like the following:
+      
+   openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.pem
+   
+   copy the content from the generated cert.pem. to create_your_cert.pem.   
+
+2. Generate one account for bindctl or other web client tools.
+
+    run command:
+    python \parkinglot\tools\usr_mgr\usr_mgr.py
+
+    The account information is saved in passwd.csv
