 **Persisted** works well with plugins like `startify` or `dashboard`. It will never restore a session automatically, but you can of course write an autocmd that does exactly that.

+The plugin's functions, alongside some example keybindings, are contained below:
 
-```lua
--- restore the session for the current directory and current branch (if `git_use_branch` is enabled)
-vim.api.nvim_set_keymap("n", "<leader>qr", [[<cmd>lua require("persisted").load()<cr>]])
+### Commands
 
--- restore the last session
-vim.api.nvim_set_keymap("n", "<leader>ql", [[<cmd>lua require("persisted").load({ last = true })<cr>]])
+- `SessionStart` - Start a session. Useful if `autosave` is set to false
+- `SessionStop` - Stop recording a session
+- `SessionLoad` - Load the session for the current directory and current branch if `git_use_branch` is enabled
+- `SessionLoadLast` - Load the last session
+- `SessionDelete` - Delete the current session
+- `SessionToggle` - Determines whether to load, start or stop a session
 
--- start persisted => if autosave is set to false
-vim.api.nvim_set_keymap("n", "<leader>qs", [[<cmd>lua require("persisted").start()<cr>]])
+### Callbacks
 
--- stop persisted => session won't be saved on exit
-vim.api.nvim_set_keymap("n", "<leader>qx", [[<cmd>lua require("persisted").stop()<cr>]])
+The plugin allows for _before_ and _after_ callbacks to be executed relative to the session. This is achieved via the `before_save` and `after_save` configuration options.
 
--- delete persisted => delete the current session
-vim.api.nvim_set_keymap("n", "<leader>qd", [[<cmd>lua require("persisted").delete()<cr>]])
+> **Note:** The author uses a _before_ callback to ensure that [minimap.vim](https://github.com/wfxr/minimap.vim) is not written into the session. Its presence prevents the exact buffer and cursor position from being restored when loading a session.
 
--- toggle persisted => determines whether to load, start or stop a session
-vim.api.nvim_set_keymap("n", "<leader>qt", [[<cmd>lua require("persisted").toggle()<cr>]])

+### Lazy loading
+
+To lazy load the plugin, consider adding the `module = "persisted"` option if you're using packer. The commands may then be called with `<cmd>lua require("persisted").toggle()<cr>` for example. The only command which differs is `SessionLoadLast` which is called with `<cmd>lua require("persisted").load({ last = true })<cr>`.
