+### Local Installation
+
+To run AIP locally, follow the next steps:
+
+* Clone the AIP repository:
+    * `git clone https://github.com/stratosphereips/AIP.git ~/AIP`
+* Access the AIP folder:
+    * `cd ~/AIP`
+* Create a Python Virtual Environment to install the requirements
+    * `python3 -m venv aip-venv`
+* Activate the virtual environment
+    * `source aip-venv/bin/activate`
+* Install the Python requirements:
+    * `pip install -r requirements.txt`
+* Set the PYTHONPATH environment variable so Python knows where to find all AIP components:
+    * `export PYTHONPATH=$(pwd)/lib`
+* Let's test that AIP works with a simple test:
+    * `python3 bin/aip --help`
