 ## Installation
 
 [LazyAlgebra](https://github.com/emmt/LazyAlgebra.jl) is a prerequisite for
-.  To install `LazyAlgebra`, simply do:
+LinearInterpolators.  See [Documentation of
+LazyAlgebra](https://emmt.github.io/LazyAlgebra.jl/dev/install/) for installing
+this package.
+
+LinearInterpolators is not yet an [official Julia package][julia-url] so you
+have to clone the repository.  In Julia, hit the `]` key to switch to the
+package manager REPL (you should get a `... pkg>` prompt) and type:
 
 ```julia
-Pkg.clone("https://github.com/emmt/LazyAlgebra.jl.git")
+pkg> add "https://github.com/emmt/LinearInterpolators.jl.git"
 ```
