 this project is designed to hook with `pd` and `tikv` which you can find in `PingCap` github page.
 
-When you work with this project, you have to communicate with `pd` and `tikv`. There is a script taking care of this. By executing the following commands, `pd` and `tikv` can be executed on background.
-```
-cd scripts
-make pd
-make tikv
-```

-## How to use for now
-Since it's not quite complete, a usage sample for now can be given is:
-```java
-// Init tidb cluster configuration
-TiConfiguration conf = TiConfiguration.createDefault("127.0.0.1:2379");
-TiSession session = TiSession.create(conf);
-Catalog cat = session.getCatalog();
-TiDBInfo db = cat.getDatabase("tpch_test");
-TiTableInfo table = cat.getTable(db, "customer");
-Snapshot snapshot = session.createSnapshot();
- 
-// Generate select ranges
-ByteString startKey = TableCodec.encodeRowKeyWithHandle(table.getId(), Long.MIN_VALUE);
-ByteString endKey = TableCodec.encodeRowKeyWithHandle(table.getId(), Long.MAX_VALUE);
-Coprocessor.KeyRange keyRange = Coprocessor.KeyRange.newBuilder().setStart(startKey).setEnd(endKey).build();
-List<Coprocessor.KeyRange> ranges = new ArrayList<>();
-ranges.add(keyRange);
-
- 
-// Create select request
-TiSelectRequest selectRequest = new TiSelectRequest();
-selectRequest.addRanges(ranges);
-selectRequest.addField(TiColumnRef.create("c_mktsegment", table));
-selectRequest.setTableInfo(table);
-selectRequest.setStartTs(session.getTimestamp().getVersion());
-selectRequest.addWhere(new GreaterEqual(TiConstant.create(5), TiConstant.create(5)));
-selectRequest.addGroupByItem(TiByItem.create(TiColumnRef.create("c_mktsegment"), false));
-selectRequest.setLimit(10);
-selectRequest.bind();
- 
-// Fetch data
-Iterator<Row> iterator = snapshot.select(selectRequest);
-System.out.println("Show result:");
-while (iterator.hasNext()) {
-  Row rowData = iterator.next();
-  for (int i = 0; i < rowData.fieldCount(); i++) {
-    System.out.print(rowData.get(i, null) + "\t");
-  }
-  System.out.println();
-}
-
-```
-Result:
-```java
-Show result:
-BUILDING	
-AUTOMOBILE	
-MACHINERY	
-HOUSEHOLD	
-FURNITURE	
-```
+When you work with this project, you have to communicate with `pd` and `tikv`. Please run TiKV and PD in advance.
