-##### Example
-
-Imagine a scenario where projects have multiple participants, and participants can be involved in multiple projects. This many-to-many relationship is facilitated through an association table.
-
-Define the models:
-
-```python
-class Project(Base):
-    __tablename__ = 'projects'
-    id = Column(Integer, primary key=True)
-    name = Column(String)
-    description = Column(String)
-    participants = relationship("Participant", secondary=projects_participants_association)
-
-
-class Participant(Base):
-    __tablename__ = 'participants'
-    id = Column(Integer, primary key=True)
-    name = Column(String)
-    role = Column(String)
-    projects = relationship("Project", secondary=projects_participants_association)
-
-
-class ProjectsParticipantsAssociation(Base):
-    __tablename__ = "projects_participants_association"
-    project_id = Column(Integer, ForeignKey("projects.id"), primary key=True)
-    participant_id = Column(Integer, ForeignKey("participants.id"), primary key=True)
-```
-
-Fetch projects along with their participants:
-
-```python
-from fastcrud import FastCRUD, JoinConfig
-
-crud_project = FastCRUD(Project)
-
-joins_config = [
-    JoinConfig(
-        model=ProjectsParticipantsAssociation,
-        join_on=Project.id == ProjectsParticipantsAssociation.project_id,
-        join_prefix="pp_",
-        join_type="inner",
-    ),
-    JoinConfig(
-        model=Participant,
-        join_on=ProjectsParticipantsAssociation.participant_id == Participant.id,
-        join_prefix="participant_",
-        join_type="inner",
-    )
-]
-
-projects_with_participants = await crud_project.get_multi_joined(
-    db_session, 
-    joins_config=joins_config,
-)
-```
-
-The result will be:
+Now, `projects_with_participants['data']` will contain projects along with their participant information. The full results would look like:
