fix java-refactor

Provide a method to disable autoformat on save lsp fallback for
specified filetypes. By default disable for C/C++ as an example,
because it does not have a well standardized coding style.

-### Introduction
+# kickstart.nvim
+
+## Introduction
 
 A starting point for Neovim that is:
 
-* Small (~370 lines)
+* Small
 * Single-file
-* Documented
-* Modular
+* Completely Documented
 
-Kickstart.nvim targets *only* the latest ['stable'](https://github.com/neovim/neovim/releases/tag/stable) and latest ['nightly'](https://github.com/neovim/neovim/releases/tag/nightly) of Neovim. If you are experiencing issues, please make sure you have the latest versions.
+**NOT** a Neovim distribution, but instead a starting point for your configuration.
 
-This repo is meant to be used as a starting point for a user's own configuration; remove the things you don't use and add what you miss. This configuration serves as the reference configuration for the [lspconfig wiki](https://github.com/neovim/nvim-lspconfig/wiki).
+## Installation
 
-### Installation
+### Install Neovim
 
-* Backup your previous configuration
-* Copy and paste the kickstart.nvim `init.lua` into `$HOME/.config/nvim/init.lua`
-* Start Neovim (`nvim`) and run `:PackerInstall` - ignore any error message about missing plugins, `:PackerInstall` will fix that shortly
-* Restart Neovim
+Kickstart.nvim targets *only* the latest
+['stable'](https://github.com/neovim/neovim/releases/tag/stable) and latest
+['nightly'](https://github.com/neovim/neovim/releases/tag/nightly) of Neovim.
+If you are experiencing issues, please make sure you have the latest versions.
 
-If there are languages that you don't want to use, remove their configuration and notes from your `init.lua` after copy and pasting (for example, in the mason configuration).
+### Install External Dependencies
 
-### Configuration
+> **NOTE**
+> [Backup](#FAQ) your previous configuration (if any exists)
 
-You could directly modify the `init.lua` file with your personal customizations. This option is the most straightforward, but if you update your config from this repo, you may need to reapply your changes.
+External Requirements:
+- Basic utils: `git`, `make`, `unzip`, C Compiler (`gcc`)
+- [ripgrep](https://github.com/BurntSushi/ripgrep#installation)
+- A [Nerd Font](https://www.nerdfonts.com/): optional, provides various icons
+  - if you have it set `vim.g.have_nerd_font` in `init.lua` to true
+- Language Setup:
+  - If want to write Typescript, you need `npm`
+  - If want to write Golang, you will need `go`
+  - etc.
 
-An alternative approach is to create a separate `custom.plugins` module to register your own plugins. In addition, you can handle further customizations in the `/after/plugin/` directory (see `:help load-plugins`). See the following examples for more information. Leveraging this technique should make upgrading to a newer version of this repo easier. 
+> **NOTE**
+> See [Windows Installation](#Windows-Installation) to double check any additional Windows notes
 
-#### Example `plugins.lua`
+Neovim's configurations are located under the following paths, depending on your OS:
 
-The following is an example of a `plugins.lua` module (located at `$HOME/.config/nvim/lua/custom/plugins.lua`) where you can register your own plugins. 
+| OS | PATH |
+| :- | :--- |
+| Linux, MacOS | `$XDG_CONFIG_HOME/nvim`, `~/.config/nvim` |
+| Windows (cmd)| `%userprofile%\AppData\Local\nvim\` |
+| Windows (powershell)| `$env:USERPROFILE\AppData\Local\nvim\` |
+
+### Install Kickstart
+
+Clone kickstart.nvim:
+
+<details><summary> Linux and Mac </summary>
+
+```sh
+git clone https://github.com/nvim-lua/kickstart.nvim.git "${XDG_CONFIG_HOME:-$HOME/.config}"/nvim
+```
+
+</details>
+
+<details><summary> Windows </summary>
+
+If you're using `cmd.exe`:
+
+```
+git clone https://github.com/nvim-lua/kickstart.nvim.git %userprofile%\AppData\Local\nvim\
+```
+
+If you're using `powershell.exe`
+
+```
+git clone https://github.com/nvim-lua/kickstart.nvim.git $env:USERPROFILE\AppData\Local\nvim\
+```
+
+</details>
+
+### Post Installation
+
+Start Neovim
+
+```sh
+nvim
+```
+
+That's it! Lazy will install all the plugins you have. Use `:Lazy` to view
+current plugin status.
+
+Read through the `init.lua` file in your configuration folder for more
+information about extending and exploring Neovim.
+
+### Getting Started
+
+[The Only Video You Need to Get Started with Neovim](https://youtu.be/m8C0Cq9Uv9o)
+
+### Recommended Steps
+
+[Fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo) this repo
+(so that you have your own copy that you can modify) and then install. You
+can install it on your machine using the methods above.
+
+> **NOTE**
+> Your fork's url will be something like this: `https://github.com/<your_github_username>/kickstart.nvim.git`
+
+#### Examples of adding popularly requested plugins
+
+NOTE: You'll need to uncomment the line in the init.lua that turns on loading custom plugins.
+
+<details>
+  <summary>Adding autopairs</summary>
+
+This will automatically install [windwp/nvim-autopairs](https://github.com/windwp/nvim-autopairs) and enable it on startup. For more information, see documentation for [lazy.nvim](https://github.com/folke/lazy.nvim).
+
+In the file: `lua/custom/plugins/autopairs.lua`, add:
 
 ```lua
-return function(use)
-  use({
-    "folke/which-key.nvim",
+-- File: lua/custom/plugins/autopairs.lua
+
+return {
+  "windwp/nvim-autopairs",
+  -- Optional dependency
+  dependencies = { 'hrsh7th/nvim-cmp' },
   config = function()
-        require("which-key").setup({})
-      end
-  })
-end
+    require("nvim-autopairs").setup {}
+    -- If you want to automatically add `(` after selecting a function or method
+    local cmp_autopairs = require('nvim-autopairs.completion.cmp')
+    local cmp = require('cmp')
+    cmp.event:on(
+      'confirm_done',
+      cmp_autopairs.on_confirm_done()
+    )
+  end,
+}
 ```
 
-#### Example `defaults.lua`
+</details>
+<details>
+  <summary>Adding a file tree plugin</summary>
 
-For further customizations, you can add a file in the `/after/plugin/` folder (see `:help load-plugins`) to include your own options, keymaps, autogroups, and more. The following is an example `defaults.lua` file (located at `$HOME/.config/nvim/after/plugin/defaults.lua`).
+This will install the tree plugin and add the command `:Neotree` for you. For more information, see the documentation at [neo-tree.nvim](https://github.com/nvim-neo-tree/neo-tree.nvim).
+
+In the file: `lua/custom/plugins/filetree.lua`, add:
 
 ```lua
-vim.opt.relativenumber = true
+-- File: lua/custom/plugins/filetree.lua
 
-vim.keymap.set('n', '<leader>sr', require('telescope.builtin').resume, { desc = '[S]earch [R]esume' })
+return {
+  "nvim-neo-tree/neo-tree.nvim",
+  version = "*",
+  dependencies = {
+    "nvim-lua/plenary.nvim",
+    "nvim-tree/nvim-web-devicons", -- not strictly required, but recommended
+    "MunifTanjim/nui.nvim",
+  },
+  config = function ()
+    require('neo-tree').setup {}
+  end,
+}
 ```
 
-### Contribution
+</details>
 
-Pull-requests are welcome. The goal of this repo is not to create a Neovim configuration framework, but to offer a starting template that shows, by example, available features in Neovim. Some things that will not be included:
+### FAQ
 
-* Custom language server configuration (null-ls templates)
-* Theming beyond a default colorscheme necessary for LSP highlight groups
-* Lazy-loading. Kickstart.nvim should start within 40 ms on modern hardware. Please profile and contribute to upstream plugins to optimize startup time instead.
+* What should I do if I already have a pre-existing neovim configuration?
+  * You should back it up and then delete all associated files.
+  * This includes your existing init.lua and the neovim files in `~/.local` which can be deleted with `rm -rf ~/.local/share/nvim/`
+* Can I keep my existing configuration in parallel to kickstart?
+  * Yes! You can use [NVIM_APPNAME](https://neovim.io/doc/user/starting.html#%24NVIM_APPNAME)`=nvim-NAME` to maintain multiple configurations. For example, you can install the kickstart configuration in `~/.config/nvim-kickstart` and create an alias:
+    ```
+    alias nvim-kickstart='NVIM_APPNAME="nvim-kickstart" nvim'
+    ```
+    When you run Neovim using `nvim-kickstart` alias it will use the alternative config directory and the matching local directory `~/.local/share/nvim-kickstart`. You can apply this approach to any Neovim distribution that you would like to try out.
+* What if I want to "uninstall" this configuration:
+  * See [lazy.nvim uninstall](https://github.com/folke/lazy.nvim#-uninstalling) information
+* Why is the kickstart `init.lua` a single file? Wouldn't it make sense to split it into multiple files?
+  * The main purpose of kickstart is to serve as a teaching tool and a reference
+    configuration that someone can easily use to `git clone` as a basis for their own.
+    As you progress in learning Neovim and Lua, you might consider splitting `init.lua`
+    into smaller parts. A fork of kickstart that does this while maintaining the 
+    same functionality is available here:
+    * [kickstart-modular.nvim](https://github.com/dam9000/kickstart-modular.nvim)
+  * Discussions on this topic can be found here:
+    * [Restructure the configuration](https://github.com/nvim-lua/kickstart.nvim/issues/218)
+    * [Reorganize init.lua into a multi-file setup](https://github.com/nvim-lua/kickstart.nvim/pull/473)
 
-Each PR, especially those which increase the line count, should have a description as to why the PR is necessary.
+### Windows Installation
+
+Installation may require installing build tools and updating the run command for `telescope-fzf-native`
+
+See `telescope-fzf-native` documentation for [more details](https://github.com/nvim-telescope/telescope-fzf-native.nvim#installation)
+
+This requires:
+
+- Install CMake and the Microsoft C++ Build Tools on Windows
+
+```lua
+{'nvim-telescope/telescope-fzf-native.nvim', build = 'cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release && cmake --build build --config Release && cmake --install build --prefix build' }
+```
+
+Alternatively, one can install gcc and make which don't require changing the config,
+the easiest way is to use choco:
+
+1. install [chocolatey](https://chocolatey.org/install)
+either follow the instructions on the page or use winget,
+run in cmd as **admin**:
+```
+winget install --accept-source-agreements chocolatey.chocolatey
+```
+
+2. install all requirements using choco, exit previous cmd and
+open a new one so that choco path is set, and run in cmd as **admin**:
+```
+choco install -y neovim git ripgrep wget fd unzip gzip mingw make
+```
+
+Then, continue with the [Install Kickstart](#Install-Kickstart) step.

+
+Kickstart.nvim is a project to help you get started on your neovim journey.
+
+                                                            *kickstart-is-not*
+It is not:
+- Complete framework for every plugin under the sun
+- Place to add every plugin that could ever be useful

+It is:
+- Somewhere that has a good start for the most common "IDE" type features:
+    - autocompletion
+    - goto-definition
+    - find references
+    - fuzzy finding
+    - and hinting at what more can be done :)
+- A place to _kickstart_ your journey.
+    - You should fork this project and use/modify it so that it matches your
+      style and preferences. If you don't want to do that, there are probably
+      other projects that would fit much better for you (and that's great!)!
