-Define your structs and types in one place. TypedStructor generates `defstruct`, type specs, and `@enforce_keys` while keeping your code clean and explicit.
+TypedStructor eliminates the boilerplate of defining Elixir structs, type specs, and enforced keys separately. Define them once, keep them in sync automatically.
 
-## Why TypedStructor?

-**Without TypedStructor**, you write everything twice:
+**Before** -- three declarations that must stay in sync manually:

-Same result, half the boilerplate. Your struct definition and type spec stay in sync automatically.
+## Feature Highlights
+
+- **Single definition** -- struct, type spec, and `@enforce_keys` generated from one block
+- **Nullable by default** -- unenforced fields without defaults automatically include `| nil`
+- **Fine-grained null control** -- override nullability per-field or per-block with the `:null` option
+- **Opaque and custom types** -- generate `@opaque`, `@typep`, or rename the type from `t()`
+- **Type parameters** -- define generic/parametric types
+- **Multiple definers** -- supports structs, exceptions, and Erlang records
+- **Plugin system** -- extend behavior at compile time with composable plugins
+- **Nested modules** -- define structs in submodules with the `:module` option

-This generates a struct and type where fields are nullable by default (`pos_integer() | nil`).
-
-### Enforcing Required Fields
-
-Make fields non-nullable by enforcing them:
-
-```elixir
-typed_structor do
-  field :id, pos_integer(), enforce: true  # Required, never nil
-  field :name, String.t()                  # Optional, can be nil
-end
-```
-
-### Providing Defaults
-
-Fields with defaults don't need to be nullable since they always have a value:
-
-```elixir
-typed_structor do
-  field :id, pos_integer(), enforce: true
-  field :name, String.t(), default: "Unknown"  # String.t() (not nullable)
-  field :age, non_neg_integer()                # non_neg_integer() | nil
-end
-```
-
-### Controlling Nullability
-
-You can explicitly control whether fields accept `nil`:
-
-```elixir
-typed_structor do
-  field :id, integer(), null: false       # Never nil
-  field :name, String.t(), null: true     # Always nullable
-end
-```
-
-Or set defaults for all fields in a block:
+### Nullability Rules
 
-```elixir
-typed_structor null: false do
-  field :id, integer()                         # Not nullable by default
-  field :email, String.t()                     # Not nullable by default
-  field :phone, String.t(), null: true         # Override for this field
-end
-```
-
-The interaction between `enforce`, `default`, and `null` follows this logic:
+The interaction between `:enforce`, `:default`, and `:null` determines whether a field's type includes `nil`:
 
 | `:default` | `:enforce` | `:null` | Type includes `nil`? |

 ## Options
 
-TypedStructor provides several options to customize your type definitions:
-
 ### Opaque Types
 
 Use `type_kind: :opaque` to hide implementation details:
 
 ```elixir
 typed_structor type_kind: :opaque do
-  field :id, pos_integer()
   field :secret, String.t()
 end
-
 # Generates: @opaque t() :: %__MODULE__{...}
 ```
 
 ### Custom Type Names
 
-Override the default `t()` type name with `type_name`:

-### Integration with Other Tools
+## Plugins
 
-Skip struct generation to use with Ecto or other schema tools:
+Extend TypedStructor's behavior with plugins that run at compile time:
 
 ```elixir
-defmodule User do
-  use TypedStructor
+typed_structor do
+  plugin Guides.Plugins.Accessible
 
-  typed_structor module: Profile, define_struct: false do
-    @derive {Jason.Encoder, only: [:email]}
-    field :email, String.t(), enforce: true
+  field :id, pos_integer()
+  field :name, String.t()
+end
+```
 
-    use Ecto.Schema
-    @primary_key false
+See the [Plugin Guides](https://hexdocs.pm/typed_structor/introduction.html) for examples and instructions on writing your own.
 
-    schema "users" do
-      Ecto.Schema.field(:email, :string)
-    end
+## Documentation
 
-    import Ecto.Changeset
+Add `@typedoc` inside the block, and `@moduledoc` at the module level as usual:
 
-    def changeset(%__MODULE__{} = user, attrs) do
-      user
-      |> cast(attrs, [:email])
-      |> validate_required([:email])
-    end
+```elixir
+defmodule User do
+  @moduledoc "User account data"
+  use TypedStructor
+
+  typed_structor do
+    @typedoc "A user with authentication details"
+
+    field :id, pos_integer()
+    field :name, String.t()
   end

-## Plugins
+### Integration with Other Libraries
 
-Extend TypedStructor's behavior with plugins. They run during compilation to add functionality:
+Use `define_struct: false` to skip struct generation when another library defines the struct:
 
 ```elixir
 defmodule User do
   use TypedStructor
 
-  typed_structor do
-    plugin Guides.Plugins.Accessible  # Adds Access behavior
-
-    field :id, pos_integer()
-    field :name, String.t()
-  end
-end
-
-user = %User{id: 1, name: "Phil"}
-get_in(user, [:name])  # => "Phil"

-## Documentation
-
-Add `@moduledoc` at the module level, and `@typedoc` inside the block:
-
-```elixir
-defmodule User do
-  @moduledoc "User management structures"
-  use TypedStructor
+  typed_structor define_struct: false do
+    field :email, String.t(), enforce: true
 
-  typed_structor do
-    @typedoc "A user with authentication details"
+    use Ecto.Schema
+    @primary_key false
 
-    field :id, pos_integer()
-    field :name, String.t()
+    schema "users" do
+      Ecto.Schema.field(:email, :string)
+    end
   end
 end
 ```

+This generates only the type spec while letting the other library handle the struct definition.
