 Technology and cost assumptions
 ##########################################
 
-Add text here.
+*Techno-Economic Assumptions*
+
+For the technological assumptions (cost,efficiency, lifetime, etc.), we take estimates for the investment year specified in the `config file <https://github.com/PyPSA/pypsa-eur-sec/blob/3daff49c9999ba7ca7534df4e587e1d516044fc3/config.default.yaml#L43>`_. Many of those come from a database published by the Danish Energy Agency (`DEA <https://ens.dk/en/our-services/projections-and-models/technology-data>`_). Assumptions are maintained at the `technology data repository <https://github.com/PyPSA/technology-data>`_.
