+# Guide
+
+**1\.** 
+
+Check the contents of the request/response to the license server
+
+**2\.**
+
+Create a python scheme file according to the reference described below.
+
+Scheme files are located in python/schemes.
+
+The scheme file should only describe the part that handles the license acquisition and will eventually be concatenated and executed as pre.py+SCHEME.py+after.py.
+
+**3\.**
+
+Edit popup.html to allow the added scheme file to run.
+
+**4\.**
+
+Edit the Config files as needed.
+
+# References of scheme file
+
+*licUrl*: License URL as String
+
+*licHeaders*: Headers as JSON object
+
+*licBody*: Request payloads of License server as Base64 String
+
+*js.corsFetch()*: Use this method instead of pyfetch if the license server requires that the Origin header be set to the original domain. Otherwise, pyfetch should be used.
