 # E(T)LT pour Plesna
 
+## Installation
+
+## Concepts
+
+- `dataplatform`: agrégation d'un datacatalogue, de moteur de compute et du dag des transformations.
+- `datacatalogue`: gestion du contenu des datastores.
+- `datastore`: interface de stockage des données.
+- `compute`: moteur de traitement des fluxs.
+- `graph/dag`: organisation logique des fluxs et des données.
+
 ## Stages
