"## Getting set up\n",
"\n",
"1. **Install conda**:\n",
" If you don't have conda installed, you can follow the [conda docs](https://conda.io/projects/conda/en/latest/user-guide/install/index.html) to download and install it. We recommend using the [Miniconda](https://conda.io/miniconda.html) installer.\n",
"\n",
"2. **Open a new terminal window**\n",
" \n",
"3. **Create and activate a new conda environment**: This environment is just for `anaconda-project`, a tool to help download the required packages and data for the tutorial.\n",
" ```bash\n",
" conda create -n project \"anaconda-project>=0.11\"\n",
" conda activate project\n",
" ```\n",
"\n",
"4. **Download and navigate to the tutorial project**: If you've previously run the `anaconda-project download` command below, you may need to delete or rename the pre-existing `holoviz_tutorial` directory.\n",
" ```bash\n",
" anaconda-project download pyviz/holoviz_tutorial\n",
" cd holoviz_tutorial\n",
" ```\n",
"\n",
"5. **Launch Jupyter**: Don't be alarmed when this command outputs many lines as it downloads packages, sets up another conda environment just for the tutorial, and then launches Jupyter.\n",
" ```bash\n",
" anaconda-project run jupyter lab\n",
" ```\n",
" Note: You can replace \"lab\" with \"notebook\" if you prefer the original Jupyter notebook interface.\n",
"\n",
"5. **Test HoloViz imports**:\n",
"After launching Jupyter, navigate to this notebook (`tutorial/00_Setup.ipynb`) and run the following cell. This command is a quick check that your environment is set up correctly. You should see the HoloViews, Bokeh, and Matplotlib logos along with a success message.\n"
