docs(readme): rewrite README with disclaimer to source repo

Remove screenshots, add disclaimer linking to magidc/nvim-config as the
upstream source. Keep Installation, UI Theme, Custom Mappings and
Featured Plugins sections. Drop IDE mappings, Troubleshooting and
Feedback sections.

 # Neovim configuration for Java, Python, Rust and Lua
 
-This is my personal LUA based configuration for Neovim that I use on a daily basis as Java, Python and RUST IDE. This setup is the product of continuous enhancements based in what I have found in configurations shared by other users. It is an ongoing project that may evolve with time as I come accross with new plugins, refine mappings or refactor configuration files.<br>Feel free to fork this repository and adapt it to your own needs.

 # Installation
 ## Manual Setup
 0. Clone this repository into `~/.config/nvim`:
     ```
     git clone --depth 1 https://github.com/venkatarenduchintala/nvim-config.git ~/.config/nvim
     ```
-1. Install latest [NeoVIM version](https://github.com/neovim/neovim/wiki/Installing-Neovim). The configuration also includes an script to install automatically Neovim in APT based Linux distributions (Debian, Ubuntu, PopOs...). See [install_nvim.sh](https://github.com/magidc/nvim-config/blob/master/install_nvim.sh)
-2. Install [ripgrep](https://github.com/BurntSushi/ripgrep) into your OS. It is required by some [Telescope](https://github.com/nvim-telescope/telescope.nvim) plugin searching modes.
-
-3. This environment is preconfigured with Language Server Providers (LSP) and Debug Adapters  (DAP) for Java, Python, Rust and Lua. These components provide IDE features like autocompletions, error highlight or debugging. As it is required to have installed these components in your system, this Neovim setup relies on [mason.nvim](https://github.com/mason-org/mason.nvim#installation) plugin to install them automatically if they are missing.
-<br>
-
-# UI theme
-Several UI themes are preconfigured in this setup. Active theme is set by editing file `lua/settings.lua`.
-Default active theme is [Tokyonight](https://github.com/folke/tokyonight.nvim).
+1. Install latest [Neovim](https://github.com/neovim/neovim/wiki/Installing-Neovim).
+2. Install [ripgrep](https://github.com/BurntSushi/ripgrep) — required by some [Telescope](https://github.com/nvim-telescope/telescope.nvim) search modes.
+3. LSP servers and DAP adapters (Java, Python, Rust, Lua) are managed automatically by [mason.nvim](https://github.com/mason-org/mason.nvim) on first launch.

-# Custom mappings
-Most of mappings are defined in file `lua/mappings.lua`. WhichKey plugin is used in order to provide a description for each one of them.
-Other mappings can be found in specific plugin configuration files in `lua/plugins/configs` directory. Also, language specific mappings are defined in LSP config files, these mappings are only available when working with specific programming languages (when LSP are attached)
+# UI Theme
+Several UI themes are preconfigured. The active theme is set in `lua/settings.lua`.
+Default: [Tokyonight](https://github.com/folke/tokyonight.nvim).

-# Equivalent mapping configurations for other IDEs VIM integrations
-I have created configuration files with (almost) equivalent mappings for [Eclipse IDE vim plugin (vrapper)](https://github.com/magidc/dotfiles/blob/master/vrapperrc), [IntelliJ vim plugin (ideaVim)](https://github.com/magidc/dotfiles/blob/master/jetbrains/ideavimrc) and [VSCode vim plugin (vscodevim)](https://github.com/magidc/dotfiles/blob/master/vscode/keybindings.json).
-These configurations will allow users who are used to these key combinations to remain confortable and efficient while working with other IDEs.
+# Custom Mappings
+Core mappings are defined in `lua/mappings.lua`. [WhichKey](https://github.com/folke/which-key.nvim) provides inline descriptions for all bindings.
+Plugin-specific mappings live in `lua/plugins/configs/`. LSP mappings are defined in `lua/lsp/` and are only active when a language server is attached.
