 # Description
 
-The operation `--realise` essentially “builds” the specified store
-paths. Realisation is a somewhat overloaded term:
-
-  - If the store path is a *derivation*, realisation ensures that the
-    output paths of the derivation are [valid] (i.e.,
-    the output path and its closure exist in the file system). This
-    can be done in several ways. First, it is possible that the
-    outputs are already valid, in which case we are done
-    immediately. Otherwise, there may be [substitutes]
-    that produce the outputs (e.g., by downloading them). Finally, the
-    outputs can be produced by running the build task described
-    by the derivation.
-
-  - If the store path is not a derivation, realisation ensures that the
-    specified path is valid (i.e., it and its closure exist in the file
-    system). If the path is already valid, we are done immediately.
-    Otherwise, the path and any missing paths in its closure may be
-    produced through substitutes. If there are no (successful)
-    substitutes, realisation fails.
 
+Each of *paths* is processed as follows:
+
+- If the path leads to a [store derivation]:
+  1. If it is not [valid], substitute the store derivation file itself.
+  2. Realise its [output paths]:
+    - Try to fetch from [substituters] the [store objects] associated with the output paths in the store derivation's [closure].
+      - With [content-addressed derivations] (experimental): Determine the output paths to realise by querying content-addressed realisation entries in the [Nix database].
+    - For any store paths that cannot be substituted, produce the required store objects. This involves first realising all outputs of the derivation's dependencies and then running the derivation's [`builder`](@docroot@/language/derivations.md#attr-builder) executable. <!-- TODO: Link to build process page #8888 -->
+- Otherwise, and if the path is not already valid: Try to fetch the associated [store objects] in the path's [closure] from [substituters].
+
+If no substitutes are available and no store derivation is given, realisation fails.
