-## Queries and Mutations
-You can see a list of [sample queries here](https://discuss.dgraph.io/t/list-of-test-queries/22).
-Dgraph also supports mutations via GraphQL syntax.
-Because GraphQL mutations don't contain complete data, the mutation syntax uses [RDF NQuad format](https://www.w3.org/TR/n-quads/).
-```
-mutation {
-  set {
-		<subject> <predicate> <objectid> .
-		<subject> <predicate> "Object Value" .
-		<subject> <predicate> "объект"@ru .
-		_uid_:0xabcdef <predicate> <objectid> .
-	}
-}
-```
-
-You can batch multiple NQuads in a single GraphQL query.
-Dgraph would assume that any data in `<>` is an external id (XID),
-and it would retrieve or assign unique internal ids (UID) automatically for these.
-You can also directly specify the UID like so: `_uid_: 0xhexval` or `_uid_: intval`.
-
-Note that a `delete` operation isn't supported yet.
-
-In addition, you could couple a mutation with a follow up query, in a single GraphQL query like so.
-```
-mutation {
-  set {
-		<alice> <follows> <greg> .
-	}
-}
-query {
-	me(_xid_: alice) {
-		follows
-	}
-}
-```
-The query portion is executed after the mutation, so this would return `greg` as one of the results.
