# How to connect

> SPQR router and coordinator admin console

Router and coordinator have administrative console. This is an app that works by PostgreSQL protocol and you can connect to it by usual psql:

```sql theme={null}
➜  psql "host=localhost sslmode=verify-full user=demo dbname=demo port=7432"
		SPQR router admin console
	Here you can configure your routing rules
------------------------------------------------
	You can find documentation here 
https://github.com/pg-sharding/spqr/tree/master/docs

SHOW shards;
 listing data shards 
---------------------
 shard id -> shard1
 shard id -> shard2
(2 rows)
```

Administrative Console is the place where you configure the sharding logic. The router will decide which of the shards to send each request to according to the settings.
