-#### Dvote Tree
+## dvote Tree
 
 Implementation of dvote tree structure. Currently based on iden3 merkle tree.
 
 Example of usage:
 
 ```
-  T := tree.Tree {namespace: "vocdoni"}
-  if T.init() != nil { fmt.Println("Cannot create tree database") }
-  err := T.addClaim([]byte("Hello you!"))
+  T := tree.Tree
+  if T.Init() != nil { fmt.Println("Cannot create tree database") }
+  err := T.AddClaim([]byte("Hello you!"))
   if err != nil {
     fmt.Println("Claim already exist")
   }
-  mpHex, err := T.genProof([]byte("Hello you!"))
+  mpHex, err := T.GenProof([]byte("Hello you!"))
   fmt.Println(mpHex)
-  fmt.Println(T.checkProof([]byte("Hello you!"), mpHex))
-  T.close()
+  fmt.Println(T.CheckProof([]byte("Hello you!"), mpHex))
+  T.Close()
 ```
