+Understanding Tensors
+===========================
+
+Before diving into PyTensor, it's essential to understand the fundamental 
+data structure it operates on: the *tensor*. A *tensor* is a multi-dimensional 
+array that serves as the foundation for symbolic computations.
+
+tensors can represent anything from a single number (scalar) to 
+complex multi-dimensional arrays. Each tensor has a type that dictates its 
+dimensionality and the kind of data it holds.
+
+For example, the following code creates a symbolic scalar and a symbolic matrix:
+
+>>> x = pt.scalar('x')
+>>> y = pt.matrix('y')
+
+Here, `scalar` refers to a tensor with zero dimensions, while `matrix` refers 
+to a tensor with two dimensions. The same principles apply to tensors of other 
+dimensions.
+
+For more information about tensors and their associated operations can be 
+found here: :ref:`tensor <libdoc_tensor>`.
