-# What is Mimir?
+### 📜 What is Mimir?
 
-Mimir is a service that allows you to easily query real-time data from the Nine Chronicles chain via GraphQL.
-Since all data is stored in DocumentDB (MongoDB), fast queries through indexing are possible.
+Mimir is a real-time data query service for the Nine Chronicles chain, built on GraphQL. With data stored in **DocumentDB (MongoDB)**, you get fast queries and indexed results.

-## Structure
+### 🔧 Structure
 
-Mimir is composed of Mimir, which provides GraphQL, Mimir.Worker, which syncs data, and a database.
-Mimir.Worker periodically fetches chain data and stores it in the database (MongoDB), while Mimir provides this data via GraphQL.
+Mimir includes three main parts:  
+1. **Mimir** - Provides the GraphQL service.  
+2. **Mimir.Worker** - Syncs chain data regularly.  
+3. **MongoDB** - Stores and indexes the data.

-## Check Sync Index
+---
 
-Mimir synchronizes Nine Chronicles chain data with Mimir's database using Pollers.
-Due to this, there may be differences between the actual chain and the stored data, and you can check which index the data is stored up to through the metadata collection.
+### 📊 Check Sync Index
+
+Mimir syncs chain data using **Pollers**. Since data may differ slightly from the chain, you can check the latest data block index with the following query:
 
 ```graphql
