+# Docker compose setup for Trino + Redis/Valkey
+
+## Official Docs:
+- [Trino](https://trino.io/docs/current/connector/redis.html)
+- [Valkey (open-source Redis)](https://valkey.io/download/)
+
+## Project Structure
+
+```

+├──── data/
+│     └── ... # empty folder for redis usage
+├──── etc/

+```
+
+## Instructions
+
+### Steps to Run
+
+1. Pull containers:
+
+```sh
+docker pull trinodb/trino
+docker pull valkey/valkey
+```
+
+2. Start the services:
+
+```sh
+docker-compose up -d
+```
+
+### Example Usage
+
+1. Connect to Valkey:
+
+```sh
+docker exec -it valkey redis-cli
+```
+
+2. Insert some data:
+
+```r
+HSET example_table:1 field1 "Alice" field2 "Wonderland" field3 "25";
+```
+
+3. Connect to Trino:
+
+```sh
+docker exec -it trino trino
+```
+
+4. Run a sample query:
+
+```sql
+SELECT * FROM redis.default.example_table;
+```
+
+You should see this:
+
+```
+id        | field1 |   field2    | field3 
+-----------------+--------+-------------+--------
+ example_table:2 | Bob    | Builderland | 30     
+ example_table:1 | Alice  | Wonderland  | 25     
+(2 rows)
