+# Jupyter Notebook with a Rust, R, and python kernel
+
+Steps to get it working:
+
+1. Install `uv`. See https://docs.astral.sh/uv/getting-started/installation/
+
+2. Start a new project:
+
+```
+uv init notebook_hello
+cd notebook_hello
+```
+
+3. Add the python kernel you prefer, e.g. version 3.13
+
+```
+uv add --dev ipykernel
+uv run ipython kernel install --user --name notebook_hello
+uv run --python 3.13 --with jupyter jupyter lab
+```
+
+4. Set up the R kernel
+
+ - Install `R`. See https://www.r-project.org/
+ - Set up the R kernel
+
+```
+Rscript -e "install.packages('IRkernel'); IRkernel::installspec(); "
+```
+
+5. Set up the Rust kernel
+
+ - Install Rust. See https://www.rust-lang.org/tools/install
+
+```
+cargo install jupyter
+cargo install evcxr_jupyter
+```
+
+6. Run the notebook server
+
+```
+uv run --with jupyter jupyter lab
+```
+
+
+
+
+
+
+You should see a notebook with the option to switch between Rust, Python, and R kernels.
