-# What are mutations
+# What are Mutations
+
+In GraphQL, a mutation is a type of query used to make changes to data on the server. It is used to create, update, or delete data, and is structured similarly to a query, but with a "mutation" field at the top level instead of a "query" field.
+
+A mutation typically includes fields that specify the data to be changed and the operation to be performed (e.g. "create", "update", or "delete"). It can also include arguments to specify the specific data to be affected.

+# Multiple Mutation Fields

+In GraphQL, it is possible to perform multiple mutations in a single query by including multiple "mutation" fields in the query. This is called "batching" or "chaining" mutations.

-# Operation name
+# Operation Name
+
+In GraphQL, an operation name is an optional identifier that can be used to uniquely identify a query or a mutation in a document containing multiple operations. It can be used to provide more meaningful names for operations, making it easier to understand the purpose of the operation and to identify it in the event of an error.
