+# The Collections API
+
+The ICollectionManager class exposes methods to manage the assets collections:
+
+```python
+from unreal_engine import ICollectionManager
+
+print(ICollectionManager.get_collection())
+```
+
+The api expects knowledge of a bunch of enums mapped as int:
+
+`ECollectionShareType`
+
+```c
+enum Type
+{
+    CST_System,
+    CST_Local,
+    CST_Private,
+    CST_Shared,
+    CST_All,
+}
+```
+
+`ECollectionStorageMode`
+
+```c
+enum Type
+{
+    Static,
+    Dynamic,
+}
+```
+
+
+
+### get_collections()
+
+returns the list of collections as a tuple with the form (name, ECollectionShareType)
