 # How to manage Julia Language Server
-This config use sysimage built with PackageCompiler to make language server startup faster.
-Scripts in this directory is for management of sysimage.
+This config use sysimage built with PackageCompiler to make language server starts faster.
+Scripts in this directory are for management of the sysimage.
 
 # description
 all related process is done in project at `~/.julia/environments/nvim-lspconfig/`.
 
-## startup
+## install (or minor update of Julia)
 ```sh
-$ ./setup_julials.sh
+julia ./setup_julials.jl
 ```
-which executes `add_dependencies.jl` internally.
+Run Language Server with `--tracecompile` option from any editor.
 
 ## update
 ```sh
-$ ./update_julials.sh
+julia ./update_julials.sh
 ```
 which updates project, compile sysimage, then do precompile.
+To use the sysimage, run Language Server with `-J ~/.julia/environments/nvim-lspconfig/` option.
 
 # effect
 Start up got about x3 - x4 faster.
 It still takes some time to load packages though.
 
-# TODO
-- [ ] Not sure all necessary packages are listed in add_dependencies.jl
-- [ ] Maybe it's better to set up different sysimages for each projects
