+
+# Local Installation
+
+## Installation
+
+```
+cd /path/to/your/projects/folder
+git clone https://github.com/poke1024/vectorian-2021-demo
+cd vectorian-2021-demo
+conda env create -f environment.yml
+```
+
+The `conda` command usually takes 5 to 10 minutes.
+
+## Launching
+
+```
+conda activate vectorian-demo
+cd /path/to/your/projects/folder
+cd vectorian-2021-demo
+jupyter notebook publication.ipynb
+```
+
+Executing the first code cell will take some time.
+
+## Troubleshooting
+
+Sometimes the Bokeh server wants a different port. Running
+
+```
+import os
+os.environ["BOKEH_ALLOW_WS_ORIGIN"] = "localhost:8890"
+```
+
+inside Jupyter can help.
