 # Restoring vim and neovim sessions
 
+## `persistence.nvim` strategy
+- when using [persistence.nvim](https://github.com/folke/persistence.nvim) by Folke, tmux-resurrect will call on it to load sessions if they exist
+- in `.tmux.conf` or `.config/tmux/tmux.conf`:
+  
+    ```sh
+    set -g @resurrect-strategy-nvim 'persistence'
+    ```
+## native session strategy
 - save vim/neovim sessions. I recommend
   [tpope/vim-obsession](https://github.com/tpope/vim-obsession) (as almost every
   plugin, it works for both vim and neovim).
-- in `.tmux.conf`:
-
-        # for vim
-        set -g @resurrect-strategy-vim 'session'
-        # for neovim
-        set -g @resurrect-strategy-nvim 'session'
-
+- in `.tmux.conf` or `.config/tmux/tmux.conf`:
+    
+    ```sh
+    # for vim
+    set -g @resurrect-strategy-vim 'session'
+    # for neovim
+    set -g @resurrect-strategy-nvim 'session'
+    ```
 `tmux-resurrect` will now restore vim and neovim sessions if `Session.vim` file
 is present.
