+###Creating time-limited poll
+
+To create a poll user has to send a message over waku network on specific topic 
+
+`/{dapp name}/waku-polling/polls-init/proto`
+
+For a poll to be started waku message has to have specific fields:
+
+```proto
+message PollInit {
+    bytes owner = 1; // Address of a poll owner/initializer
+    int64 timestamp = 2; // Timestamp of a waku message
+    string question = 3;// Question of a poll
+    repeated answers = 4; // Possible answers to poll
+    enum PollType {
+        WEIGHTED = 0;
+        NON_WEIGHTED = 1;
+    }
+    PollType pollType = 5 // type of poll
+    optional bytes minToken = 6 // amount of token needed for NON_WEIGHTED poll to be able to vote
+    int64 endTime = 7 // UNIX timestamp of poll end
+    bytes signature = 8 // signature of all above fields
+}
+```
