 ### What is the store like?
 
 - Lots of files that look like {hash}-package-version
+
+---
+
+### Example
+
+```
+/gnu/store/spxcaq8gnmckhzz9a1wm3qc9dmz5bvsd-gcc-toolchain-12.3.0
+```
+
+---
+
+### What is the store like?
+
 - Hash is derived from a build dependency graph
     - A program can use any version of a library it needs
     - A program build hash is unique, if any dependency changes the hash will as well.
