+---@brief
+---
+---A kotlin language server which was developed for internal usage and
+-- released afterwards. Maintaining is not done by the original author,
+-- but by fwcd.
+
+-- It is built via gradle and developed on github.
+-- Source and additional description:
+-- https://github.com/fwcd/kotlin-language-server
+
+-- This server requires vim to be aware of the kotlin-filetype.
+-- You could refer for this capability to:
+-- https://github.com/udalov/kotlin-vim (recommended)
+-- Note that there is no LICENSE specified yet.
+
+-- For faster startup, you can setup caching by specifying a storagePath
+-- in the init_options. The default is your home directory.
