 `TensorDict` is a dictionary-like class that inherits properties from tensors,
 such as indexing, shape operations, casting to device etc.

+Installation
+============
+
+Tensordict releases are synced with PyTorch, so make sure you always enjoy the latest
+features of the library with the `most recent version of PyTorch <https://pytorch.org/get-started/locally/>`__ (although core features
+are guaranteed to be backward compatible with pytorch>=1.13).
+Nightly releases can be installed via
+
+.. code-block::
+
+  $ pip install tensordict-nightly
+
+or via a `git clone` if you're willing to contribute to the library:
+
+.. code-block::
+
+  $ cd path/to/root
+  $ git clone https://github.com/pytorch/tensordict
+  $ cd tensordict
