 -------
 
-.. doxygenclass:: kp::Manager
-   :members:
+The Kompute Manager provides a high level interface to simplify interaction with underlying kp::Sequences of kp::Operations.

 Sequence
 -------
 
-.. doxygenclass:: kp::Sequence
-   :members:
+The Kompute Sequence consists of batches of kp::Operations, which are executed on a respective GPU queue. The execution of sequences can be synchronous or asynchronous, and it can be coordinated through its respective vk::Fence.

 Tensor
 -------
 
-.. doxygenclass:: kp::Tensor
-   :members:
+The kp::Tensor is the atomic unit in Kompute, and it is used primarily for handling Host and GPU Device data.

 Algorithm
 -------
 
-.. doxygenclass:: kp::Algorithm
-   :members:
+The kp::Algorithm consists primarily of the components required for shader code execution, including the relevant vk::DescriptorSet relatedresources as well as vk::Pipeline and all the relevant Vulkan resources as outlined in the architectural diagram.

 OpBase
 -------
 
-.. doxygenclass:: kp::OpBase
-   :members:
+The kp::OpBase provides a top level class for an operation in Kompute, which is the step that is executed on a GPU submission. The Kompute operations can consist of one or more kp::Tensor.

 OpAlgoBase
 -------
 
+The vk::OpAlgoBase extends the vk::OpBase class, and provides the base for shader-based operations. Besides of consisting of one or more vk::Tensor as per the vk::OpBase, it also contains a unique vk::Algorithm.

 OpMult
 -------
 
+The kp::OpMult operation is a sample implementation of the kp::OpAlgoBase class. This class shows how it is possible to create a custom vk::OpAlgoBase that can compile as part of the binary. The kp::OpMult operation uses the shader-to-cpp-header-file script to convert the script into cpp header files.

 -------
 
-.. doxygenclass:: kp::OpTensorCreate
-   :members:
+The kp::OpTensorCreate is a tensor only operations which initialises a kp::Tensor by creating the respective vk::Buffer and vk::Memory, as well as transferring the local data into the GPU.
