+# Tmux Configuration
+
+This directory contains the tmux configuration, reusable tmuxifier layouts, and
+session persistence settings.
+
+## Session Persistence
+
+The configuration uses tmux-resurrect and tmux-continuum to save sessions every
+15 minutes and restore the latest saved session when tmux starts. Sessions save
+window and pane layouts, working directories, and pane contents. Running
+programs are restored only when supported by tmux-resurrect; their live process
+state cannot survive a shutdown.
+
+After starting tmux, install the configured plugins with:
+
+```text
+Ctrl-Space I
+```
+
+`Ctrl-Space` is the configured tmux prefix. You can also save or restore
+manually with:
+
+```text
+Ctrl-Space Ctrl-S  Save the current tmux state
+Ctrl-Space Ctrl-R  Restore the last saved state
+```
