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
+## Introduction
 
 A starting point for Neovim that is:
 
 * Small
-* Single-file (with examples of moving to multi-file)
-* Documented
-* Modular
+* Single-file
+* Completely Documented
 
-This repo is meant to be used by **YOU** to begin your Neovim journey; remove the things you don't use and add what you miss.
+**NOT** a Neovim distribution, but instead a starting point for your configuration.
 
-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.
+## Installation
 
-Distribution Alternatives:
-- [LazyVim](https://www.lazyvim.org/): A delightful distribution maintained by @folke (the author of lazy.nvim, the package manager used here)

+### Install External Dependencies
 
 > **NOTE**
 > [Backup](#FAQ) your previous configuration (if any exists)
 
-Requirements:
-* Make sure to review the readmes of the plugins if you are experiencing errors. In particular:
-  * [ripgrep](https://github.com/BurntSushi/ripgrep#installation) is required for multiple [telescope](https://github.com/nvim-telescope/telescope.nvim#suggested-dependencies) pickers.
-* See [Windows Installation](#Windows-Installation) if you have trouble with `telescope-fzf-native`
+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.
+
+> **NOTE**
+> See [Windows Installation](#Windows-Installation) to double check any additional Windows notes

-The `Lazy` plugin manager will start automatically on the first run and install the configured plugins - as can be seen in the introduction video. After the installation is complete you can press `q` to close the `Lazy` UI and **you are ready to go**! Next time you run nvim `Lazy` will no longer show up.
+That's it! Lazy will install all the plugins you have. Use `:Lazy` to view

-### Configuration And Extension
+#### Examples of adding popularly requested plugins
 
-* Inside of your copy, feel free to modify any file you like! It's your copy!
-* Feel free to change any of the default options in `init.lua` to better suit your needs.
-* For adding plugins, there are 3 primary options:
-  * Add new configuration in `lua/custom/plugins/*` files, which will be auto sourced using `lazy.nvim` (uncomment the line importing the `custom/plugins` directory in the `init.lua` file to enable this)
-  * Modify `init.lua` with additional plugins.
-  * Include the `lua/kickstart/plugins/*` files in your configuration.
+NOTE: You'll need to uncomment the line in the init.lua that turns on loading custom plugins.
 
-You can also merge updates/changes from the repo back into your fork, to keep up-to-date with any changes for the default configuration.

-### Contribution
-
-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:
-
-* Custom language server configuration (null-ls templates)
-* Theming beyond a default colorscheme necessary for LSP highlight groups
-
-Each PR, especially those which increase the line count, should have a description as to why the PR is necessary.

-### Hints And Tips For New Neovimmers
+Alternatively, one can install gcc and make which don't require changing the config,
+the easiest way is to use choco:
 
-Neovim is a very rich and powerful environment, but it can also feel a bit
-intimidating for new users trying to find their way around, especially if
-they're coming from other environments like Visual Studio Code or a traditional
-IDE.
+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
+```
 
-There's no way this README can provide you with everything you need to know, but
-here are a few tips so you can learn how to learn.
+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
+```
 
-### Use The Help, Luke!
-
-Neovim's help system is incredibly thorough and extensive. You should really
-take a moment to get comfortable navigating through help topics, going back and
-forth, navigating the menus, etc. This won't just help you read the help, it
-will empower you in the rest of your Neovim journey.
-
-You can double click on a topic to drill down, and hit Ctrl-o (Hold down the
-Control key and the 'o' key) to go back.
-
-Read the first page you get when you run :help carefully. it will serve you
-well.
-
-You can also get help on a particular thing by typing ":help <topic>".
-
-Like, let's say we want to learn more about folding, just type ":help folding".
-
-### To The Telescope!
-
-One of the more powerful features you get by installing this project is the
-brilliant Telescope plugin co-written by @tjdevries.
-
-Take a minute to browse through ":help telescope" and get a sense for all the
-amazing superpowers you've gained.
-
-In particular, there are two Telescope features that are incredible for helping
-you understand how to do a particular thing or how to configure a particular
-feature.
-
-If you're not sure what to look for, try ":Telescope help_tags". Let's say we
-want to configure Neovim to automatically word wrap. We might type ":Telescope
-help_tags" and then type w, r, a, p. Notice how the list of results changes with
-each new letter you type? When you're done you've got a screen full of topics
-involving word wrap.
-
-Another common question is "What keys do I hit to make a thing happen?". To get
-an answer, one way is to use ":Telescope keymaps". You'll get the same list of
-results that changes to adapt with each new key you press.
-
-With these hints in mind you should be in good shape to get learning. Remember,
-you are on a journey of discovery here, adapting your programming environment to
-your needs. It will take effort, but the rewards are worth it! :)
+Then, continue with the [Install Kickstart](#Install-Kickstart) step.
