 GraphScope Interactive is a specialized construction of [GraphScope Flex](https://github.com/alibaba/GraphScope/tree/main/flex), designed to handle concurrent graph queries at an impressive speed. Its primary goal is to process as many queries as possible within a given timeframe, emphasizing a high query throughput rate.
 For the full documentation of GraphScope Interactive, please refer to [GraphScope-Interactive](https://graphscope.io/docs/interactive_engine/graphscope_interactive).
+
+## Minimal tutorial
+
+In this minimal tutorial, we will show you how to run graph service on builtin modern graph.
+
+### Preparation
+
+Set `location` to `/home/graphscope/default_graph`.
+
+### init database
+
+```bash
+./bin/gs_interactive init -c ./conf/interactive.yaml
+```
+
+### Start service
+
+```bash
+./bin/gs_interactive service start
+```
+
+### Stop service
+```bash
+./bin/gs_interactive service stop
+```
+
+### Restart service 
+```bash
+./bin/gs_interactive service restart
+```
+
+### Get service status
+```bash
+./bin/gs_interactive service status
+```
+
+### Compile stored procedure
+```bash
+./bin/gs_interactive procedure compile -g modern -i ./examples/modern_graph/count_vertex_num.cypher
+```
+
+### Disable stored procedure
+```bash
+./bin/gs_interactive procedure disable -g modern -n count_vertex_num
+```
+
+### Enable stored procedure
+```bash
+./bin/gs_interactive procedure enable -g modern -n count_vertex_num
+```
+
+### Use user defined graph
+```bash
+./bin/gs_interactive service stop
+./bin/gs_interactive database remove -g modern
+./bin/gs_interactive database create -g test -c ./examples/modern_graph/modern_graph.yaml
+./bin/gs_interactive database import -g test -c ./examples/modern_graph/bulk_load.yaml
+./bin/gs_interactive service start -g test
+```
