 # Bricks!
 
-`make build`
+This is an early PoC at this stage!
 
-`./bricks test`
+`make build` (or download artifacts)
 
-the rest will follow someday.
+Reuses authentication from Databricks CLI. And terraform provider. See details here: https://registry.terraform.io/providers/databrickslabs/databricks/latest/docs#environment-variables
+
+Supports:
+* Databricks CLI
+* Databricks CLI Profiles
+* Azure CLI Auth
+* Azure MSI Auth
+* Azure SPN Auth
+* Google OIDC Auth
+* Direct `DATABRICKS_HOST`, `DATABRICKS_TOKEN` or `DATABRICKS_USERNAME` + `DATABRICKS_PASSWORD` variables.
+
+What works:
+
+* `./bricks fs ls /`
+* `./bricks test`
+* `./bricks run test.py`
+
+What doesn't work:
+
+* Everything else.
