+## Introduction
+
+The eduGAIN Connectivity Check Service (ECCS), uses two Service Provider belonging to different NREN that are members of eduGAIN interfederation.
+The ECCS Python script gets the SPs' HTTP-Post AssertionConsumerService URL from the "sps-metadata.xml" file placed into "input" directory.
+The mechanism chosen to update regularly the "sps-metadata.xml" file involves the PyFF Metadata Aggregator because it allows to download the eduGAIN metadata, validate it with eduGAIN metadata certificate, consider only two SP interested by ECCS and create the "sps-metadata.xml" file as output.
+The following instruction will help to install, configure and use PyFF for ECCS.
+
+## Requirements
+
+* Python >= 3.7
+
+## Install
+
+1) Create another Virtualenv for PyFF:
+   * `$HOME/eccs/python/bin/virtualenv --python=$HOME/eccs/python/bin/python3 pyff-venv`
+
+2) Upgrade PIP:
+   * `$HOME/eccs/pyff-venv/bin/python3 -m pip install --upgrade pip`
+
+3) Activate PyFF Virtualenv:
+   * `source $HOME/eccs/pyff-venv/bin/activate`
+   
+4) Install PyFF:
+   * `pip install -U pyff`
+   
+## Configure
+
+1) For Python 3.10:
+   * `vim $HOME/eccs/pyff-venv/lib/python3.10/site-packages/xmlsec/crypto.py`
+
+     "from collections import MutableMapping as DictMixin" have to be:
+     "from collections.abc import MutableMapping as DictMixin"
+     
+2) Download eduGAIN metadata certificate:
+   * `cd $HOME/eccs/pyff-config`
+   * `wget "https://technical.edugain.org/mds-v2.cer" -O edugain-signer.crt`
+
+## Automating SPs metadata download
+
+Configure the cron job for the local user to automate downloading SPs metadata:
+
+   * `crontab -e`
+
+     ```bash
+     00 7 * * * $HOME/eccs/pyff-venv/bin/pyff $HOME/eccs/pyff-config/sps-metadata.xml
+     ```
