 # Installation
-*Author: Ahmed Ratnani*
 
-It is recommanded to use a virtual environement.
+To be able to run the examples in this guide, we recommend to follow these steps:
 
+1. Download the [IGA-Python] source files.
+
+```bash
+git clone https://github.com/pyccel/IGA-Python.git
+
+# Save and show the absolute path to the IGA-Python directory.
+IGA_PYTHON_DIR=$(realpath IGA-Python)
+echo "IGA_PYTHON_DIR=${IGA_PYTHON_DIR}"
+```
+
+2. Create a virtual Python environment.
 
 ```shell
-# create a virtual environement
 python3 -m venv iga-python-env
 
-# activate this environement using 
-source iga-python-env/bin/activate
+# Save and show the absolute path to the IGA-Python environment script.
+IGA_PYTHON_ENV=$(realpath iga-python-env/bin/activate)
+echo "IGA_PYTHON_ENV=${IGA_PYTHON_ENV}"
 ```
 
-Then install dependencies using
+2. Install the necessary Python packages.
 
 ```shell
-pip3 install 'psydac[extra] @ git+https://github.com/pyccel/psydac.git@devel#egg=psydac'
-pip3 install notebook
+cd ${IGA_PYTHON_DIR}
+
+# Python packages required by IGA-Python will 
+# be installed in IGA-Python virtual environment.
+source ${IGA_PYTHON_ENV}
+pip3 install -r requirements.txt
 ```
 
-Adding the virtual environement to Jupyter notebook, can be done using
+3. Launch Jupyter notebook.
 
 ```shell
-python3 -m ipykernel install --user --name=.iga-python
+jupyter notebook
 ```
+
+The above command should automatically launch your web browser and show you the [IGA-Python] files you've downloaded from Step 1:

+
+Try opening a sample notebook. Navigate to `chapter1/` and find `poisson.ipynb`:
+
+![png](images/ch1-jupyter-poisson-1.png)
+
+
+Open `poisson.ipynb`. Check that you can successfully run all cells in this notebook.
