 ## Install
 
 ### Install from PyPi
 
+The package is available on PyPi with CUDA 12.1.1 wheels:
+
 ```
 pip install autoawq-kernels
 ```
 
+### Install release wheels
+
+For ROCm and other CUDA versions, you can use the wheels published at each [release](https://github.com/casper-hansen/AutoAWQ_kernels/releases/):
+
+```
+pip install https://github.com/casper-hansen/AutoAWQ_kernels/releases/download/v0.0.2/autoawq_kernels-0.0.2+rocm561-cp310-cp310-linux_x86_64.whl
+```
+
 ### Build from source
+You can also build from source:
 
 ```
 git clone https://github.com/casper-hansen/AutoAWQ_kernels
 cd AutoAWQ_kernels
 pip install -e .
 ```
+
+To build for ROCm, you need to first install the following packages `rocsparse-dev hipsparse-dev rocthrust-dev rocblas-dev hipblas-dev`.
