+Sometimes, it is necessary to normalize the values coming in, therefore *attrs* comes with converters.
 
 Attributes can have a `converter` function specified, which will be called with the attribute's passed-in value to get a new value to use.
 This can be useful for doing type-conversions on values that you don't want to force your callers to do.

 ## Hooking Yourself Into Initialization
 
-Generally speaking, the moment you think that you need finer control over how your class is instantiated than what *attrs* offers, it's usually best to use a {obj}`classmethod` factory or to apply the [builder pattern](https://en.wikipedia.org/wiki/Builder_pattern).

 However, sometimes you need to do that one quick thing before or after your class is initialized.
-And for that *attrs* offers three means:
+For that purpose, *attrs* offers the following options:
 
 - `__attrs_pre_init__` is automatically detected and run *before* *attrs* starts initializing.

 However it takes a lot of bias and determined rationalization to claim that *attrs* raises the mental burden on a project given how difficult it is to find the important bits in a hand-written class and how annoying it is to ensure you've copy-pasted your code correctly over all your classes.
