 This should install compatible versions of JAX and Triton.
 
-JAX-Triton does depend on Jaxlib but it's usually a more stable dependency. You might be able to get away with using a recent jaxlib release:
-```bash
-$ pip install jaxlib[cuda]
-$ # or
-$ pip install jaxlib[cuda11_pip]
-$ # or
-$ pip install jaxlib[cuda12_pip]

-If you find there are issues with the latest Jaxlib release, you can try using a Jaxlib nightly.
-To install a new jaxlib, you can find a link to a [CUDA 11 nightly](https://storage.googleapis.com/jax-releases/jaxlib_nightly_cuda_releases.html) or [CUDA 12 nightly](https://storage.googleapis.com/jax-releases/jaxlib_nightly_cuda12_releases.html). Then install it via:
-```bash
-$ pip install 'jaxlib @ <link to nightly>'
-```
-or to install CUDA via pip automatically, you can do:
 ```bash
-$ pip install 'jaxlib[cuda11_pip] @ <link to nightly>'
-$ # or
-$ pip install 'jaxlib[cuda12_pip] @ <link to nightly>'
+$ pip install jaxlib[cuda12]

+In rare cases JAX-Triton might need a nighly version of jaxlib. You can install
+it following the instructions
