 ## Installation instructions
 
+This package resides in the `ITensor/ITensorRegistry` local registry.
+In order to install, simply add that registry through your package manager.
+This step is only required once.
 ```julia
 julia> using Pkg: Pkg
 
-julia> Pkg.add(url="https://github.com/ITensor/TensorAlgebra.jl")
+julia> Pkg.Registry.add(url="https://github.com/ITensor/ITensorRegistry")
+```
+or:
+```julia
+julia> Pkg.Registry.add(url="[email protected]:ITensor/ITensorRegistry.git")
+```
+if you want to use SSH credentials, which can make it so you don't have to enter your Github ursername and password when registering packages.
+
+Then, the package can be added as usual through the package manager:
+
+```julia
+julia> Pkg.add("TensorAlgebra")
 ```
