 # Pre-requisite

+## Terminal emulators
+
+Which [terminal emulator](https://en.wikipedia.org/wiki/Terminal_emulator) we choose to use greatly affects the appearance and features of Nvim.
+Since Nvim supports true colors, terminals that support true colors are preferred.
+For a list of terminals that support true colors, see [here](https://github.com/termstandard/colors).
+
+For macOS, we can use [kitty](https://sw.kovidgoyal.net/kitty/), [iterm2](https://www.iterm2.com/), [wezterm](https://wezfurlong.org/wezterm/) or [Alacritty](https://github.com/jwilm/alacritty).
+
+If you ssh to Linux server on Windows, I recommend [wsltty](https://github.com/mintty/wsltty) and [Cygwin](https://www.cygwin.com/),
+both of them use [mintty](https://github.com/mintty/mintty) as the terminal emulator.
+For the latest version of Windows 10, you can also try [Windows Terminal](https://github.com/microsoft/terminal).
+
+## Patched Fonts
+
+Since statusline or file explorer plugins often use Unicode symbols not available in normal font,
+we need to install a patched font from the [nerd-fonts](https://github.com/ryanoasis/nerd-fonts) project.
+
+# Automatic installation
+
+## Automatic Installation for Linux
+
+To set up a workable Nvim environment on Linux,
+I use [a bash script](nvim_setup_linux.sh) to automatically install necessary dependencies, Nvim itself and configs.
+
+Note that the variable `PYTHON_INSTALLED`, `SYSTEM_PYTHON` and `ADD_TO_SYSTEM_PATH` in the script
