 # TOTP server for technical site
 
 This is a simple back-end server meant to run in a secure enviromnent full with access to the database where users' TOTP secrets are stored.
-The server used HTTP to respond to GET queries. It azzepts two parameters
-- user - here you provide the user identifier as passed form eduTEAMS - this argument is mandatory
-- otp - the one-time time-based code entered by the user, this is optional

 ## Installation
 
-The server works with the **otp** database which is shared with the thechnical site installation.
+The server works with the **otp** database which is shared with the technical site installation.
 You must define user **otp** or whatever you decide to call it (and set in the otp_config.php).
 
 
 ### Without Docker
 
-All you need is a https server with pho and mysql support. The server will need to make outside connections to the database host.

 If you run stuff within secure environment (as you should) you do not need https.
