+# SymbolicIndexingInterface.jl: Arrays of Arrays and Even Deeper
+
+SymbolicIndexingInterface.jl is a set of interface functions for handling containers
+of symbolic variables. It also contains one such container: `SymbolCache`.
+
+## Installation
+
+To install SymbolicIndexingInterface.jl, use the Julia package manager:
+
+```julia
+using Pkg
+Pkg.add("SymbolicIndexingInterface")
+```
+
