+#### Install latest release
+We suggest using uv to install the latest release of ai-dynamo[sglang]. You can install it with `curl -LsSf https://astral.sh/uv/install.sh | sh`
+
+```bash
+# create a virtual env
+uv venv --python 3.12 --seed
+# install the latest release
+uv pip install "ai-dynamo[sglang]"
+```

+This requires having rust installed. We also recommend having a proper installation of the cuda toolkit as sglang requires `nvcc` to be available.
+
+```bash
+# create a virtual env
+uv venv --python 3.12 --seed
+# build dynamo runtime bindings
+uv pip install maturin
+cd $DYNAMO_HOME/lib/bindings/python
+maturin develop --uv
+cd $DYNAMO_HOME
+uv pip install .
+export PYTHONPATH="${PYTHONPATH}:$(pwd)/components/backends/sglang/src"
+# install target sglang version (you can choose any version)
+# we include the prerelease flag in order to install flashinfer rc versions
+uv pip install --prerelease=allow sglang[all]==0.4.9.post6
