+Copyright (c) 2023 Stability AI
+CreativeML Open RAIL++-M License dated July 26, 2023
+
+Section I: PREAMBLE
+
+Multimodal generative models are being widely adopted and used, and
+have the potential to transform the way artists, among other
+individuals, conceive and benefit from AI or ML technologies as a tool
+for content creation.
+
+Notwithstanding the current and potential benefits that these
+artifacts can bring to society at large, there are also concerns about
+potential misuses of them, either due to their technical limitations
+or ethical considerations.
+
+In short, this license strives for both the open and responsible
+downstream use of the accompanying model. When it comes to the open
+character, we took inspiration from open source permissive licenses
+regarding the grant of IP rights. Referring to the downstream
+responsible use, we added use-based restrictions not permitting the
+use of the model in very specific scenarios, in order for the licensor
+to be able to enforce the license in case potential misuses of the
+Model may occur. At the same time, we strive to promote open and
+responsible research on generative models for art and content
+generation.
+
+Even though downstream derivative versions of the model could be
+released under different licensing terms, the latter will always have
+to include - at minimum - the same use-based restrictions as the ones
+in the original license (this license). We believe in the intersection
+between open and responsible AI development; thus, this agreement aims
+to strike a balance between both in order to enable responsible
+open-science in the field of AI.
+
+This CreativeML Open RAIL++-M License governs the use of the model
+(and its derivatives) and is informed by the model card associated
+with the model.
+
+NOW THEREFORE, You and Licensor agree as follows:
+
+Definitions
+
+"License" means the terms and conditions for use, reproduction, and
+Distribution as defined in this document.
+
+"Data" means a collection of information and/or content extracted from
+the dataset used with the Model, including to train, pretrain, or
+otherwise evaluate the Model. The Data is not licensed under this
+License.
+
+"Output" means the results of operating a Model as embodied in
+informational content resulting therefrom.
+
+"Model" means any accompanying machine-learning based assemblies
+(including checkpoints), consisting of learnt weights, parameters
+(including optimizer states), corresponding to the model architecture
+as embodied in the Complementary Material, that have been trained or
+tuned, in whole or in part on the Data, using the Complementary
+Material.
+
+"Derivatives of the Model" means all modifications to the Model, works
+based on the Model, or any other model which is created or initialized
+by transfer of patterns of the weights, parameters, activations or
+output of the Model, to the other model, in order to cause the other
+model to perform similarly to the Model, including - but not limited
+to - distillation methods entailing the use of intermediate data
+representations or methods based on the generation of synthetic data
+by the Model for training the other model.
+
+"Complementary Material" means the accompanying source code and
+scripts used to define, run, load, benchmark or evaluate the Model,
+and used to prepare data for training or evaluation, if any. This
+includes any accompanying documentation, tutorials, examples, etc, if
+any.
+
+"Distribution" means any transmission, reproduction, publication or
+other sharing of the Model or Derivatives of the Model to a third
+party, including providing the Model as a hosted service made
+available by electronic or other remote means - e.g. API-based or web
+access.
+
+"Licensor" means the copyright owner or entity authorized by the
+copyright owner that is granting the License, including the persons or
+entities that may have rights in the Model and/or distributing the
+Model.
+
+"You" (or "Your") means an individual or Legal Entity exercising
+permissions granted by this License and/or making use of the Model for
+whichever purpose and in any field of use, including usage of the
+Model in an end-use application - e.g. chatbot, translator, image
+generator.
+
+"Third Parties" means individuals or legal entities that are not under
+common control with Licensor or You.
+
+"Contribution" means any work of authorship, including the original
+version of the Model and any modifications or additions to that Model
+or Derivatives of the Model thereof, that is intentionally submitted
+to Licensor for inclusion in the Model by the copyright owner or by an
+individual or Legal Entity authorized to submit on behalf of the
+copyright owner. For the purposes of this definition, "submitted"
+means any form of electronic, verbal, or written communication sent to
+the Licensor or its representatives, including but not limited to
+communication on electronic mailing lists, source code control
+systems, and issue tracking systems that are managed by, or on behalf
+of, the Licensor for the purpose of discussing and improving the
+Model, but excluding communication that is conspicuously marked or
+otherwise designated in writing by the copyright owner as "Not a
+Contribution."
+
+"Contributor" means Licensor and any individual or Legal Entity on
+behalf of whom a Contribution has been received by Licensor and
+subsequently incorporated within the Model.
+
+Section II: INTELLECTUAL PROPERTY RIGHTS
+
+Both copyright and patent grants apply to the Model, Derivatives of
+the Model and Complementary Material. The Model and Derivatives of the
+Model are subject to additional terms as described in
+
+Section III.
+
+Grant of Copyright License. Subject to the terms and conditions of
+this License, each Contributor hereby grants to You a perpetual,
+worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+copyright license to reproduce, prepare, publicly display, publicly
+perform, sublicense, and distribute the Complementary Material, the
+Model, and Derivatives of the Model.
+
+Grant of Patent License. Subject to the terms and conditions of this
+License and where and as applicable, each Contributor hereby grants to
+You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+irrevocable (except as stated in this paragraph) patent license to
+make, have made, use, offer to sell, sell, import, and otherwise
+transfer the Model and the Complementary Material, where such license
+applies only to those patent claims licensable by such Contributor
+that are necessarily infringed by their Contribution(s) alone or by
+combination of their Contribution(s) with the Model to which such
+Contribution(s) was submitted. If You institute patent litigation
+against any entity (including a cross-claim or counterclaim in a
+lawsuit) alleging that the Model and/or Complementary Material or a
+Contribution incorporated within the Model and/or Complementary
+Material constitutes direct or contributory patent infringement, then
+any patent licenses granted to You under this License for the Model
+and/or Work shall terminate as of the date such litigation is asserted
+or filed.

 ### Conditioning
 
 As described, conditioning is necessary for the latent diffusion process, whether empty or not. As a result, all non-image *ToLatents nodes require positive and negative conditioning inputs. Conditioning is reliant on a CLIP tokenizer provided by the Model Loader node.

 ### Image Space & VAE
 
 The ImageToLatents node doesn't require a noise node input, but requires a VAE input to convert the image from image space into latent space. In reverse, the LatentsToImage node requires a VAE input to convert from latent space back into image space.

 ### Defined & Random Seeds
 
 It is common to want to use both the same seed (for continuity) and random seeds (for variance). To define a seed, simply enter it into the 'Seed' field on a noise node. Conversely, the RandomInt node generates a random integer between 'Low' and 'High', and can be used as input to the 'Seed' edge point on a noise node to randomize your seed.

 Control means to guide the diffusion process to adhere to a defined input or structure. Control can be provided as input to non-image *ToLatents nodes from ControlNet nodes. ControlNet nodes usually require an image processor which converts an input image for use with ControlNet.

 ### LoRA
 
 The Lora Loader node lets you load a LoRA (say that ten times fast) and pass it as output to both the Prompt (Compel) and non-image *ToLatents nodes. A model's CLIP tokenizer is passed through the LoRA into Prompt (Compel), where it affects conditioning. A model's U-Net is also passed through the LoRA into a non-image *ToLatents node, where it affects noise prediction.

 ### Scaling
 
 Use the ImageScale, ScaleLatents, and Upscale nodes to upscale images and/or latent images. The chosen method differs across contexts. However, be aware that latents are already noisy and compressed at their original resolution; scaling an image could produce more detailed results.

 ### Iteration + Multiple Images as Input
 
 Iteration is a common concept in any processing, and means to repeat a process with given input. In nodes, you're able to use the Iterate node to iterate through collections usually gathered by the Collect node. The Iterate node has many potential uses, from processing a collection of images one after another, to varying seeds across multiple image generations and more. This screenshot demonstrates how to collect several images and pass them out one at a time.

+## Watermarking
+
+InvokeAI does not apply watermarking to images by default. However,
+many computer scientists working in the field of generative AI worry
+that a flood of computer-generated imagery will contaminate the image
+data sets needed to train future generations of generative models.
+
+InvokeAI offers an optional watermarking mode that writes a small bit
+of text, **InvokeAI**, into each image that it generates using an
+"invisible" watermarking library that spreads the information
+throughout the image in a way that is not perceptible to the human
+eye. If you are planning to share your generated images on
+internet-accessible services, we encourage you to activate the
+invisible watermark mode in order to help preserve the digital image
+environment.
+
+The downside of watermarking is that it increases the size of the
+image moderately, and has been reported by some individuals to degrade
+image quality. Your mileage may vary.
+
+To read the watermark in an image, activate the InvokeAI virtual
+environment (called the "developer's console" in the launcher) and run
+the command:
+
+```
+invisible-watermark -a decode -t bytes -m dwtDct -l 64 /path/to/image.png
