## What it is
mason.nvim is a Neovim plugin providing a portable package manager for installing and managing external editor tooling such as LSP servers, DAP servers, linters, and formatters. It runs everywhere Neovim runs and links installed executables into a single bin directory added to Neovim's PATH.

## Use cases
- install lsp servers for neovim
- manage linters and formatters in neovim
- install debug adapters for nvim dap
- set up editor tooling across linux macos and windows
- keep language servers updated from within neovim
- avoid manually installing language server binaries

## When to choose
- you use Neovim and want one interface to install and update LSP servers, DAP adapters, linters, and formatters
- you need editor tooling that works consistently across Linux, macOS, and Windows
- you want installed tool executables automatically available to Neovim builtins and third-party plugins

## When to avoid
- you don't use Neovim or another editor plugin ecosystem
- you prefer system package managers or manually managed toolchains
- you need a general-purpose package manager outside the editor
