+The way Roleout works is that:
+
+1. One _optionally_ defines one or more environments (e.g. `DEV`, `PROD`).
+1. One defines the databases and their schemas once (e.g., `DWH`).<br/>
+   If any environment is defined, a DB is created for each of them (e.g. `DEV_DWH.whatever`, `PROD_DWH.whatever`).
+1. One defines the virtual warehouses.<br/>
+   If any environment is defined, a virtual warehouse is created for each of them (e.g. `DEV_whatever_WH`,
+   `PROD_whatever_WH`).
+1. One defines the functional roles.
+1. One specifies the permissions matrix for databases and virtual warehouses.<br/>
+   If any environment is defined, a matrix is defined for each of them.<br/>
+   Permissions can be `Read`, `ReadWrite`, or `Full`.
+1. Each matrix forces the creation of
+
+   - One role per environment per permission, e.g.:
+
+     - `DEV_DWH_whatever_R_AR`, `PROD_DWH_whatever_R_AR` for read-only permissions.
+     - `DEV_DWH_whatever_RW_AR`, `PROD_DWH_whatever_RW_AR` for read-write permissions.
+     - `DEV_DWH_whatever_FULL_AR`, `PROD_DWH_whatever_FULL_AR` for full access permissions.
+
+   - One warehouse-specific role per environment per permission, e.g.:
+
+     - `DEV_whatever_WH_U_AR`, `PROD_whatever_WH_U_AR` for read-only permissions.
+     - `DEV_whatever_WH_UM_AR`, `PROD_whatever_WH_UM_AR` for read-write permissions.
