+- Text to video: generate a small video according to a prompt
+
+Here are some python code examples of what you can do with this agent:

+Single execution (step) mode, the single execution method is when using the step() method of the agent:

+sea_add_island_image.save("./sea_add_island_image.png")
+
+# If you'd like to keep a state across executions or to pass non-text objects to the agent, 
+# you can do so by specifying variables that you would like the agent to use. For example,
+# you could generate the first image of rivers and lakes, and ask the model to update that picture to add an island by doing the following:
+picture = {self.name}.step("Generate a picture of rivers and lakes.")
+picture.save("./picture.png")
+updated_picture = {self.name}.step("Transform the image in `picture` to add an island to it.", picture=picture)
+updated_picture.save("./updated_picture.png")
+
+capybara_sea_image = {self.name}.step("Draw me a picture of the `prompt`", prompt="a capybara swimming in the sea")
+capybara_sea_image.save("./capybara_sea_image.png")
+
+# Document question answering
+answer = {self.name}.step(
+    "In the following `document`, where will the TRRF Scientific Advisory Council Meeting take place?",
+    document=document,
+)

+
+Chat-based execution (chat), the agent also has a chat-based approach, using the chat() method:
+```
+# Clean the chat history
+{self.name}.reset()
+
+# Text to image
+capybara_image = {self.name}.chat("Show me an an image of a capybara")
