-System-wide `vim` config location might depend on your distro. On Ubuntu, it is located at `/etc/vim/vimrc`.  
-To get the runtime paths right, you'll need to set them in the vimrc, like so:  
+# System-wide `vimrc` Configuration with Vim-Plug
+
+This guide outlines the steps to set up a system-wide configuration for `vim` and install plugins using the plugin manager [Vim-Plug](https://github.com/junegunn/vim-plug). For more details on using `vim-plug`, other plugin managers, or individual plugins, consult their respective documentation or browse [VimAwesome](https://vimawesome.com/).
+
+---
+
+### 1. Setting Up the Configuration Directories
+
+First, ensure that the necessary directories for system-wide vim configuration exist.
+
+```bash
+# Create the main vim configuration directory if it doesn't exist
+mkdir -p /etc/vim
+cd /etc/vim
+```
+
+Next, create the required subdirectories with appropriate permissions:
+
+```bash
+# Create directories for autoload, colors, plugins, session data, etc.
+mkdir -m 755 autoload colors plugged session sessions
+```
+
+---
+
+### 2. Installing Vim-Plug and Color Schemes
+
+#### 2.1. Download Vim-Plug
+
+Vim-Plug is the plugin manager that will be used to install and manage plugins. Download it to the `autoload` directory:
+
+```bash
+curl -fLo /etc/vim/autoload/plug.vim https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
+```
+
+Set the appropriate permissions for the downloaded file:
+
+```bash
+chmod o+r /etc/vim/autoload/*
+```
+
+#### 2.2. Install a Color Scheme (Optional)
+
+You can choose a color scheme of your choice. For this example, we'll use the **Molokai** color scheme.
+
+```bash
+curl -fLo /etc/vim/colors/molokai.vim https://raw.githubusercontent.com/tomasr/molokai/refs/heads/master/colors/molokai.vim
+```
+
+Ensure that the color scheme file has the correct permissions:
+
+```bash
+chmod o+r /etc/vim/colors/*
+```
+
+---
+
+### 3. Configuring the `vimrc`
+
+The system-wide `vimrc` file location might vary depending on your Linux distribution. On Ubuntu, it is typically found at `/etc/vim/vimrc`. If the file doesn't exist, create it.
+
+```bash
+touch /etc/vim/vimrc
+chmod 755 /etc/vim/vimrc
+vim /etc/vim/vimrc
+```
+
+#### 3.1. Set Runtime Paths
+
+To ensure `vim` recognizes the autoload, plugin, and color scheme directories, add the following lines to your `vimrc`:
 
 ```vim
 set runtimepath+=/etc/vim/autoload
+set runtimepath+=/etc/vim/plugged
+set runtimepath+=/etc/vim/colors
 ```
-And edit other relevent lines accordingly, wherever the paths are specified.
+
+#### 3.2. Enable Vim-Plug and Install Plugins
+
+To initialize `vim-plug` and install plugins, add the following configuration to your `vimrc`. This specifies the plugin directory and lists the plugins you'd like to use.
+
+```vim
+" Initialize Vim-Plug
+call plug#begin('/etc/vim/plugged')
+
+" List plugins here
+Plug 'rust-lang/rust.vim'      " Example plugin for Rust syntax highlighting
+" Add more plugins as needed...
+
+" End plugin section
+call plug#end()
+```
+
+#### 3.3. Enable Filetype Plugins and Indentation
+
+To enable filetype-specific plugins and proper indentation, add this line to your `vimrc`:
+
+```vim
+filetype plugin indent on  " Enable filetype-based plugins and indentation
+```
+
+You can also add any other custom configurations such as tab size, line numbering, or key mappings. For a comprehensive example, refer to [my vimrc](https://git.candifloss.cc/candifloss/dotfiles/src/branch/main/vim/vimrc).
+
+---
+
+### 4. Installing the Plugins
+
+Once you've updated your `vimrc`, it’s time to install the plugins.
+
+#### 4.1. Source the `vimrc`
+
+After saving the changes to the `vimrc`, source it to apply the changes:
+
+```vim
+:source %
+```
+
+#### 4.2. Install Plugins
+
+Run the following command to install the plugins specified in your `vimrc`:
+
+```vim
+:PlugInstall
+```
+
+This will download and install all the listed plugins.
+
+---
+
+### 5. Enjoy Vim with Plugins
+
+Once the installation is complete, your system-wide `vim` should be fully configured with the desired plugins and color schemes. You're now ready to enjoy a fully customized `vim` experience!
+
+---
+
+### Troubleshooting
+
+- **Permissions**: Ensure that the directories and files in `/etc/vim` have the correct read and execute permissions for all users who need access.
+  
+- **Plugin Conflicts**: If you encounter issues with specific plugins, check their documentation for configuration options or known issues.
+
+---
+
+Enjoy your new and enhanced `vim` setup!
