 # Globs
 
-:::caution Alpha
-Globs are an alpha feature in 0.6.0. It is likely to change in behavior in followup minor
-releases. In particular, the current plan is for globs to be lazy evaluated, so that it
-can be used to set defaults, as opposed to the current implementation where it is
-evaluated as it appears.

 > The glob command, short for global, originates in the earliest versions of Bell Labs' Unix... to expand wildcard characters in unquoted arguments ...

+In the following example, the instructions are as follows:
+1. Create a shape `a`.
+2. Apply a glob rule. This immediately applies to existing shapes, i.e., `a`.
+3. Create a shape `b`. Existing glob rules are re-evaluated, and applied if they meet the

+## Global globs
+
+Triple globs apply globally to the whole diagram. The difference between a double glob and
+a triple glob is that a triple glob will apply to nested `layers` (see the section on
+[composition](/tour/composition) for more on `layers`), as well as persist across imports.

+
+:::info Imports
+If you import a file, the globs declared inside it are usually not carried over. Triple
+globs are the exception -- since they are global, importing a file with triple glob will
+carry that glob as well.
