 Normally the parser is very lax and will accept almost anything without error. Unfortunately this can make
 it very hard to debug and can lead to unexpected behaviour.
 
-Liquid also comes with a stricter parser that can be used when editing templates to give better error messages
+Liquid also comes with a parser that can be used when editing templates to give better error messages
 when templates are invalid. You can enable this new parser like this:
 
 ```ruby
-Liquid::Environment.default.error_mode = :strict
-Liquid::Environment.default.error_mode = :strict # Raises a SyntaxError when invalid syntax is used
-Liquid::Environment.default.error_mode = :warn # Adds strict errors to template.errors but continues as normal
-Liquid::Environment.default.error_mode = :lax # The default mode, accepts almost anything.
-Liquid::Environment.default.error_mode = :rigid # Uses Parser.new instead of Expression.parse for stricter parsing
+Liquid::Environment.default.error_mode = :rigid  # Raises a SyntaxError when invalid syntax is used in all tags
+Liquid::Environment.default.error_mode = :strict # Raises a SyntaxError when invalid syntax is used in some tags
+Liquid::Environment.default.error_mode = :warn   # Adds strict errors to template.errors but continues as normal
+Liquid::Environment.default.error_mode = :lax    # The default mode, accepts almost anything.
 ```
 
 If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
