+# FaceDB object initialization
+
+### FaceResult
+
+#### Parameters
+```
+id
+name
+distance
+embedding
+img
+```
+#### Methods
+
+##### show_img()
+Convenient way to see the image that is in your FaceResults object. Open a matplotlib window 
+
+### FaceResults
+
+#### Parameters
+Note that the following parameters are only going to be accessile if you just have and FaceResult in your object FaceResults
+```
+id
+name
+distance
+embedding
+img
+```
+#### Methods
+
+##### show_img()
+Convenient way to see the images that is in your FaceResults object. Open a matplotlib window 
+
+# Main features of FaceDB
+
+### FaceDB.add(name:str,img=None,embedding=None,id=None,check_similar=True,save_just_face=False,**kwargs: Additional metadata for the face.)
+Give you the possibility to add a new entry in our FaceDB database.  
+Example : 
+```
+db.add("Nelson Mandela", img="mandela.jpg", profession="Politician", country="South Africa")
+db.add("Barack Obama", img="obama.jpg", profession="Politician", country="USA")
+db.add("Einstein", img="einstein.jpg", profession="Scientist", country="Germany")
+```
+
+### FaceDB.add_many(embeddings=None,imgs=None,metadata=None,ids=None,names=None,check_similar=True)
+Give you the possibility to add several new entries in our FaceDB database at one time.   
+Example :
+```
+files = glob("faces/*.jpg") # Suppose you have a folder with imgs with names as filenames
+imgs = []
+names = []
+for file in files:
+    imgs.append(file)
+    names.append(Path(file).name)
+
+ids, failed_indexes = db.add_many(
+    imgs=imgs,
+    names=names,
+)
+```
+
+### FaceDB.recognize(img=None, embedding=None, include=None, threshold=None, top_k=1) -> False|None|FaceResults
+Try to find the name of the personne within the picture.   
+Example:
+```
+result = db.recognize(img="your_image.jpg")
+```
+### FaceDB.all(include=None) -> FaceResults
+Retrieve information about all faces in the database.   
+Example:
+```
+results = db.all(include='name')
+#Or with a list
+results = db.all(include=['name', 'img']) 
+```
+### FaceDB.all().df -> pd.DataFrame
+Easy to get your result in a Pandas DataFrame.   
+Example:
+```
+df = db.all().df
+```
+
+### FaceDB.search(embedding,include) -> FaceResults
+Search for similar faces based on the image you provided.   
+Example:
+```
+results = db.search(img="your image.jpg")
+```
+### FaceDB.get_all(include) -> FaceResults
+Get all the faces of the db according on the parameters you want.   
+Example:
+```
+results = db.get_all(include=['name', 'img'])
+``` 
+### FaceDB.update(id, name=None, embedding=None, img=None, only_face=False)
+Update value in your db.   
+Example:
+```
+db.update(id=face_id, name="John Doe", img="john_doe.jpg") 
+```
+### FaceDB.delete(id)
+Delete one element in the database.   
+Example:
+```
+db.delete(face_id)
+```
+### Face.count() -> int
+Count the number of faces in the database.   
+Example:
+```
+count = db.count()
+```
+### Face.query(embeddings,top_k=1,include: Optional[List[Literal["embeddings", "metadatas"]]] = None,where=None,)) -> FaceResults
+Make a query to the database and get the result of the db.   
+Example:
+```
+results = db.query(name="Nelson Mandela")
+```
