+# Dedal
 
-For now, this repository provides helpers for the EBRAINS container image build flow.
-The lowest spack version which should be used with this library is v0.22.0
+This repository provides functionalities to easily ```managed spack environments``` and ```helpers for the container image build flow```.
+The lowest ```spack version``` compatible with this library is ```v0.23.0```.
+
+
+        This repository also provied CLI interface. For more informations, after installing this library, call dedal --help.

+**Setting up the needed environment variables**
+    The ````<checkout path>\dedal\.env```` file contains the environment variables required for OCI registry used for caching.
+    Ensure that you edit the ````<checkout path>\dedal\.env```` file to match your environment.
+    The following provides an explanation of the various environment variables:
+
+
+       # OCI Registry Configuration Sample for concretization caches
+       # =============================
+       # The following variables configure the Harbor docker OCI registry (EBRAINS) used for caching.
+       
+       # The hostname of the OCI registry. e.g. docker-registry.ebrains.eu
+       CONCRETIZE__OCI_HOST="docker-registry.ebrains.eu"
+       
+       # The project name in the Docker registry.
+       CONCRETIZE__OCI_PROJECT="concretize_caches"
+       
+       # The username used for authentication with the Docker registry.
+       CONCRETIZE__OCI_USERNAME="robot$concretize-cache-test+user"
+       
+       # The password used for authentication with the Docker registry.
+       CONCRETIZE__OCI_HOST="###ACCESS_TOKEN###"
+        
+
+       # OCI Registry Configuration Sample for binary caches
+       # =============================
+       # The following variables configure the Harbor docker OCI registry (EBRAINS) used for caching.
+       
+       # The hostname of the OCI registry. e.g. docker-registry.ebrains.eu
+       BUILDCACHE_OCI_HOST="docker-registry.ebrains.eu"
+       
+       # The project name in the Docker registry.
+       BUILDCACHE_OCI_PROJECT="binary-cache-test"
+       
+       # The username used for authentication with the Docker registry.
+       BUILDCACHE_OCI_USERNAME="robot$binary-cache-test+user"
+       
+       # The password used for authentication with the Docker registry.
+       BUILDCACHE_OCI_HOST="###ACCESS_TOKEN###"
+
+For both concretization and binary caches, the cache version can be changed via the attributes ```cache_version_concretize``` and ```cache_version_build```. 
+The default values are ```v1```.
