 ## About
 
-Do you ever find yourself squinting at your MongoDB queries, only to realize you've made a tiny typo that's causing a big headache? We've been there too. That's why we built this nifty little tool – to save you from those pesky errors and wasted database trips.
+Do you ever find yourself squinting at your MongoDB queries, only to realize you've made a tiny typo that's causing a big headache? We've been there too. That's why this library exists: to catch those mistakes before they hit the database.
 
 ### Benefits
 
-- **Error-Free Queries**: Say goodbye to query typos and syntax errors. Our validator catches them before they cause any trouble.
-- **Efficiency Boost**: Streamline your development process by validating queries upfront, saving you time and resources.
+- **Error-Free Queries** – Say goodbye to query typos and syntax errors. The validator catches them before they cause trouble.
+- **Efficiency Boost** – Streamline your development process by validating queries upfront, saving you time and resources.
 
 ### Use Cases
 
-- **Production Systems**: Enhance the robustness of production systems by validating queries before executing them in live environments, minimizing downtime and errors.
-- **Development Environments**: Validate queries during development to catch errors early and streamline the debugging process.
-- **Testing Processes**: Integrate query validation into testing pipelines to ensure query correctness and reliability.

-## Valid query Operators
+## API
+
+`validateQuery(query[, maxDepth])`
 
-You can find all supported query operator [here](./src/allowed.ts)
+- **query** – An object representing your MongoDB query.
+- **maxDepth** *(optional)* – Limit how deep the validator should traverse nested objects. `0` (default) means unlimited depth.
+
+Returns an object with:
+
+- `isValidQuery` – `true` if no invalid operators are found.
+- `invalidFields` – an array of paths to the invalid fields.
+
+Type definitions are available in [`types/index.d.ts`](./types/index.d.ts).
+
+## Valid query operators
+
+The full list of supported operators can be found in [`src/allowed.ts`](./src/allowed.ts).
