+Add an alias for a Datasette instance:
+```bash
+dclient alias add latest https://latest.datasette.io
+dclient alias default latest
+dclient alias default-db latest fixtures
+```
+Now run queries directly:
+```bash
+dclient "select * from facetable limit 1"

+```bash
+dclient query fixtures "select * from facetable limit 1" -i latest

 ```bash
-dclient query https://latest.datasette.io/fixtures "select * from facetable limit 1"

-```bash
-dclient alias add fixtures https://latest.datasette.io/fixtures

-dclient query fixtures "select * from facetable limit 1"
+dclient databases

+dclient plugins
+dclient schema facetable
