+LanguageServer.jl can be installed with `julia` and `Pkg`:
+```sh
+julia --project=~/.julia/environments/nvim-lspconfig -e 'using Pkg; Pkg.add("LanguageServer")'
+```
+where `~/.julia/environments/nvim-lspconfig` is the location where
+the default configuration expects LanguageServer.jl to be installed.
+
+To update an existing install, use the following command:
+```sh
+julia --project=~/.julia/environments/nvim-lspconfig -e 'using Pkg; Pkg.update()'
+```
+
+Note: In order to have LanguageServer.jl pick up installed packages or dependencies in a
+Julia project, you must make sure that the project is instantiated:
+```sh
+julia --project=/path/to/my/project -e 'using Pkg; Pkg.instantiate()'
+```
