 In TypeScript, you need to declare the typing of your foreign keys, but they will still be configured by Sequelize automatically.  
 You can still, of course, use any [attribute decorator](../models/defining-models.mdx) to customize them.
 
+### Associations with extra attributes on through table
+
+When creating an N:M association, for example, with User and Project through UserProjects you might want extra attributes on the junction table like the "role" attribute.
+This relationship can be setup like this:
+
+```ts
+class UserProject extends Model<InferAttributes<UserProject>, InferCreationAttributes<UserProject>> {
+  @Attribute(DataTypes.STRING)
+  declare role: string;
+
+  declare projectId: number;
+  declare userId: number;
+}
+
+class Project extends Model<InferAttributes<Project>, InferCreationAttributes<Project>> {
+  @Attribute(DataTypes.STRING)
+  declare name: string;
+
+  declare UserProject?: NonAttribute<UserProject>;
+}
+
+class User extends Model<InferAttributes<User>, InferCreationAttributes<User>> {
+  @Attribute(DataTypes.STRING)
+  declare username: string;
+
+  @BelongsToMany(() => Project, {
+    through: UserProject,
+  })
+  declare projects?: NonAttribute<Project[]>;
+
+  declare getProjects: BelongsToManyGetAssociationsMixin<Project>;
+  declare setProjects: BelongsToManySetAssociationsMixin<Project, number>;
+  declare addProjects: BelongsToManyAddAssociationsMixin<Project, number>;
+}
+```
+
+Creating multiple associations with the same extra attributes is possible by passing a single object on the through attribute:
+```ts
+user1.setProjects([project1, project2, project3], { through: { role: 'admin' }})
+```
+
+With the [set](#association-setter-setx) and [add](#association-adder-addx) mixins different extra attributes per association can be set by passing an array of objects of the same length as the ammount of associations:
+```ts
+user1.setProjects([project1, project2, project3], {
+  through: [
+    { role: 'admin' },
+    { role: 'manager' },
+    { role: 'designer' },
+  ]
+})
+(await user1.getProducts()).map(x => x.UserProduct?.role) // [ 'admin', 'manager', 'designer' ]
+```
+
 ## Inverse Association
 
 The `BelongsToMany` association automatically creates the inverse association on the target model, which is also a `BelongsToMany` association.
