+In Elektra a specification is defined through the metadata of keys in the `spec` namespace. The specification above contains metadata for three keys:
+
+1. the parent key (`@`)
+2. `@/mydouble`
+3. `@/myfloatarray/#` (The `#` at the end of `myfloatarray/#` indicates that it is an array)
 
 The `mountpoint` metadata on the parent key sets the name of our application's config file (the location is defined by Elektra), it should
 be unique.
