 Simple client library.
 
-## Examples
+### First example: get server version
 
-All examples have `-verbose` and `-server` options.
+```
+go run examples/serverinfo/main.go
+go run examples/serverinfo/main.go -verbose
+go run examples/serverinfo/main.go -verbose -server https://demo.tada.team
+```
 
-How to get server url, team uid and chat jid:
+Any example have `-verbose` and `-server` options. Default server value is `https://web.tada.team`.

+### Authorization token
 
- * https://demo.tada.team — server url
- * dbd248d7-25c2-4e8f-a23a-99baf63223e9 – team uid
- * g-dce6f5fd-b741-40a6-aa9c-c0e928d9dac5 – chat jid
+Some examples need authorization token. You have two options:
+
+#### Bot token
  
-How to get bot token: type "/newbot <NAME>" command in @TadaBot direct chat.
+Create bot by typing `/newbot <BOTNAME>` command in @TadaBot direct chat. 
+Allowed for team admin only.
 
-### Server version
+#### Token from your personal account
 
+For server with sms authorization:
 ```
-go run examples/serverinfo/main.go
-go run examples/serverinfo/main.go -verbose
-go run examples/serverinfo/main.go -verbose -server https://demo.tada.team
+go run examples/smsauth/main.go
+```
+
+For server with Active Directory authorization:
+```
+go run examples/passwordauth/main.go
 ```
