+# How to save current tmux session
+
+To preserve your `tmux` session across reboots, you can use a combination of `tmux` and a tool called `tmux-resurrect`. `tmux-resurrect` allows you to save and restore `tmux` sessions, including the state of each pane and window.
+
+Here are the steps to install and use `tmux-resurrect`:
+
+1. **Install `tmux-resurrect`**:
+
+    First, you need to install `tmux-resurrect`. You can do this by cloning the repository and adding it to your `tmux` configuration.
+
+    ```sh
+    git clone https://github.com/tmux-plugins/tmux-resurrect ~/tmux-resurrect
+    ```
+
+2. **Configure `tmux` to use `tmux-resurrect`**:
+
+    Add the following lines to your `~/.tmux.conf` file to enable `tmux-resurrect`:
+
+    ```sh
+    set -g @plugin 'tmux-plugins/tmux-resurrect'
+    run-shell ~/tmux-resurrect/resurrect.tmux
+    ```
+
+    If you don't have a `~/.tmux.conf` file, you can create one.
+
+3. **Reload `tmux` configuration**:
+
+    After updating your `~/.tmux.conf`, reload the `tmux` configuration by running the following command inside a `tmux` session:
+
+    ```sh
+    tmux source-file ~/.tmux.conf
+    ```
+
+4. **Save the `tmux` session**:
+
+    Before rebooting, save your `tmux` session by pressing the following key combination inside a `tmux` session:
+
+    ```sh
+    Prefix + Ctrl-s
+    ```
+
+    The default `Prefix` key is `Ctrl-b`. So, you would press `Ctrl-b` followed by `Ctrl-s`.
+
+5. **Reboot your system**:
+
+    You can now safely reboot your system.
+
+    ```sh
+    sudo reboot
+    ```
+
+6. **Restore the `tmux` session**:
+
+    After the system reboots, start a new `tmux` session and restore the saved session by pressing the following key combination inside the new `tmux` session:
+
+    ```sh
+    Prefix + Ctrl-r
+    ```
+
+    Again, the default `Prefix` key is `Ctrl-b`. So, you would press `Ctrl-b` followed by `Ctrl-r`.
+
+
+By following these steps, you can save and restore your `tmux` sessions across reboots, ensuring that you don't lose your work.
