 ##### Example
-In order to generate a bearer token, you need to have wallet (which will be used to sign the token) and
+In order to generate a bearer token, you need to know the container owner key and
 the address of the sender who will do the request to FrostFS (in our case, it's a gateway wallet address).
 
 Suppose we have:
-* **NhVtreTTCoqsMQV5Wp55fqnriiUCpEaKm3** (token owner (gateway address))
+* **KxDgvEKzgSBPPfuVfw67oPQBSjidEiqTHURKSDL1R7yGaGYAeYnr** (container owner key)
+* **NhVtreTTCoqsMQV5Wp55fqnriiUCpEaKm3** (token owner address)
+* **BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K** (container id)
 
 Firstly, we need to encode the container id and the sender address to base64 (now it's base58).
 So use **base58** and **base64** utils.
 
-1. Encoding token owner id:
+1. Encoding container id:
