 ## Planned future work
 
 We are actively working on the following features:
 
-- Ship wheels for Linux, so that Linux users can `pip install torchcodec`.
 - [Ship wheels for MacOS](https://github.com/pytorch/torchcodec/issues/111), so
-  that MacOS users can `pip install torchcodec`.
+  that MacOS users can `pip install torchcodec`. For now this is only supported
+  on Linux, but MacOS users can [build from source](./CONTRIBUTING.md).
 - [GPU decoding](https://github.com/pytorch/torchcodec/pull/58)
 - [Audio decoding](https://github.com/pytorch/torchcodec/issues/85)

 Installation Instructions
 =========================
 
-We'll be providing wheels in the coming days so that you can just install
-torchcodec using ``pip``. For now, you can just build from source. You will need
-the following dependencies:
+.. note::
+    TorchCodec is only available on Linux for now. We plan to support other
+    platforms in the future.
 
-- A C++ compiler+linker. This is typically available on a baseline Linux
-  installation already.
-- cmake
-- pkg-config
-- FFmpeg
-- PyTorch nightly
+Installing torchcodec should be as simple as:
 
-Start by installing PyTorch following the `official instructions
-<https://pytorch.org/get-started/locally/>`_.
+.. code:: bash
 
-Then, the easiest way to install the rest of the dependencies is to run:
+    pip install torchcodec
 
-    conda install cmake pkg-config ffmpeg -c conda-forge
+You will need a working PyTorch installation, which you can install following
+the `official instructions <https://pytorch.org/get-started/locally/>`_.
 
-To clone and install the repo, run:
+You will also need FFmpeg installed on your system, and TorchCodec decoding
+capabilities are determined by your underlying FFmpeg installation. There are
+different options to install FFmpeg e.g.:
 
-    git clone git@github.com:pytorch/torchcodec.git
-    # Or, using https instead of ssh: git clone https://github.com/pytorch/torchcodec.git
-    cd torchcodec
+.. code:: bash
 
-    pip install -e ".[dev]" --no-build-isolation -vv
+    conda install ffmpeg
+    # or
+    conda install ffmpeg -c conda-forge
 
+Your Linux distribution probably comes with FFmpeg pre-installed as well.
 TorchCodec supports all major FFmpeg version in [4, 7].
+
+Note that installation instructions may slightly change over time. The most
+up-to-date instructions should be available from the `README
+<https://github.com/pytorch/torchcodec?tab=readme-ov-file#installing-torchcodec>`_.
