+# This file is opened in Neovim with a LanguageServer.jl process that records Julia
+# compilation statements for creating a custom sysimage.
+#
+# This file has a bunch of linter errors which will exercise the linter and record
+# statements for that. When the diagnostic messages corresponding to those errors show up in
+# the buffer the language server should be ready to accept other commands (note: this may
+# take a while -- be patient). Here are some suggestions for various LSP functionality that
+# can be exercised (your regular keybindings should work):
+#
+#  - :lua vim.lsp.buf.hover()
+#  - :lua vim.lsp.buf.definition()
+#  - :lua vim.lsp.buf.references()
+#  - :lua vim.lsp.buf.rename()
+#  - :lua vim.lsp.buf.formatting()
+#  - :lua vim.lsp.buf.formatting_sync()
+#  - :lua vim.lsp.buf.code_action()
+#  - Tab completion (if you have set this up using LSP)
+#  - ...
+#
+# When you are finished, simply exit neovim and PackageCompiler.jl will use all the recorded
+# statements to create a custom sysimage. This sysimage will be used for the language server
+# process in the future, and should result in almost instant response.
