      { "<leader>a-", "<cmd>AiderTreeDropFile<cr>", desc = "Drop File from Tree from Aider", ft = "NvimTree" },
    },
    dependencies = {
      { "folke/snacks.nvim", version = ">=2.24.0" },
      --- The below dependencies are optional
      "catppuccin/nvim",
      "nvim-tree/nvim-tree.lua",
      --- Neo-tree integration
      {
        "nvim-neo-tree/neo-tree.nvim",
        opts = function(_, opts)
          -- Example mapping configuration (already set by default)
          -- opts.window = {
          --   mappings = {
          --     ["+"] = { "nvim_aider_add", desc = "add to aider" },
          --     ["-"] = { "nvim_aider_drop", desc = "drop from aider" }
          --     ["="] = { "nvim_aider_add_read_only", desc = "add read-only to aider" }
          --   }
          -- }
          require("nvim_aider.neo_tree").setup(opts)
        end,
      },
    },

  }

After installing, run :Aider health to check if everything is set up correctly.

  -- Response timeout in ms for Aider's first output chunk.
  response_timeout = 30000,
  -- Timeout in ms for quick commands.
  quick_idle_timeout = 500,
