-react-chained-query provide a `useChainedQuery` hook that consit of a wrapper on top of react-query `useQuery`. This `useChainedQuery` hook allow chaining queries instead of runnning them concurently, it aims to solve problems that may occurs when hitting a slow backend with too many requests.

+`useChainedQuery` hook consit of a wrapper on top of react-query `useQuery`. This `useChainedQuery` hook allow chaining queries instead of runnning them concurently, it aims to solve problems that may occurs when hitting a slow backend with too many requests.
 
 By managing a queue and executing the request one after another, it could give the capability for an application to display the information sequentially.
 
+### useChainedMutations
+
+This `useChainedMutations` hook takes an array of mutations and a function to compute the variables for the next mutation in the chain. It returns an object containing a `mutate` function that triggers the chain of mutations, a `computeVariablesForNext` function that computes the variables for the next mutation, and an array of `mutationsWithRetry` that includes a retry function for each mutation.
