 Blazer tries to protect against queries which modify data (by running each query in a transaction and rolling it back), but a safer approach is to use a read only user.  Keep reading to see how to create one.
 
-## Permissions
-
-### PostgreSQL
-
-Create a user with read only permissions:
-
-```sql
-BEGIN;
-CREATE ROLE blazer LOGIN PASSWORD 'secret123';
-GRANT CONNECT ON DATABASE database_name TO blazer;
-GRANT USAGE ON SCHEMA public TO blazer;
-GRANT SELECT ON ALL TABLES IN SCHEMA public TO blazer;
-ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO blazer;
-COMMIT;
-```
-
-### MySQL
-
-Create a user with read only permissions:
-
-```sql
-GRANT SELECT, SHOW VIEW ON database_name.* TO blazer@’127.0.0.1′ IDENTIFIED BY ‘secret123‘;
-FLUSH PRIVILEGES;
-```
-
-## Authentication
-
-Don’t forget to protect the dashboard in production.
-
-### Basic Authentication
-
-Set the following variables in your environment or an initializer.
-
-```ruby
-ENV["BLAZER_USERNAME"] = "andrew"
-ENV["BLAZER_PASSWORD"] = "secret"
-```
-
-### Devise
-
-```ruby
-authenticate :user, lambda { |user| user.admin? } do
-  mount Blazer::Engine, at: "blazer"
