 ### Master Operations
 
+#### By admin and members
+
 ```rust
-  RegisterVestingAccount {
-      master_address: Option<String>, // if given, the vesting account can be unregistered
-      address: String,
-      vesting_schedule: VestingSchedule,
+  RewardUsers {
+    rewards: Vec<RewardUserRequest>,
+    master_address: Option<String>, // if given, the vesting account can be unregistered
+    vesting_schedule: VestingSchedule,
   },
 ```
-* RegisterVestingAccount   - register vesting account
-  * When creating vesting account, the one can specify the `master_address` to enable deregister feature.
+
+This creates a set of vesting accounts for the given users. The `master_address` is used to enable the deregister feature.
+If no `master_address` is given, the deregister feature is disabled.

+#### By admin only
 
 ```rust
-    DeregisterVestingAccount {
-        address: String,
-        denom: Denom,
-        vested_token_recipient: Option<String>,
-        left_vesting_token_recipient: Option<String>,
-    },
+  Withdraw {
+    amount: Uint128,
+    recipient: String,
+  },
 ```
+
+This allows to get part or all of the unallocated amount from the contract and sends it to the `recipient`. Unallocated is equal to the
+amount sent on instantiation minus the already rewarded to users.

+#### By master_address only
