 # pomodoro-mode
 
-Add a simple [pomodoro](https://en.wikipedia.org/wiki/Pomodoro_Technique) timer to your Emacs mode-line. To run the timer, type `M-x pomodoro-mode`. To stop the timer, type `M-x pomodoro-mode` once again. The package is not on Melpa, but it is relatively easy to install in Emacs 30.1 with
+Add a simple [pomodoro](https://en.wikipedia.org/wiki/Pomodoro_Technique) timer to your Emacs mode-line.
+
+Defaults to `🍅 (MM:SS)` when working and `🥫 (MM:SS)` when taking a break.
+
+## Installation
+
+The package can be manually installed by saving `pomodoro-mode.el` to `~/emacs.d/` or wherever your emacs configuration is stored and load the package with
+```cl
+(add-to-list 'load-path "~/.emacs.d/") ; Adjust this path if necessary
+
+(require 'pomodoro-mode)
+```
+
+In Emacs 30.1 and above, `use-package` works well with version control, allowing the following
 ```cl
 (use-package pomodoro-mode
   :ensure (pomodoro-mode :host github :repo "jjanzenn/pomodoro-mode"))
 ```
+
+## Usage
+
+- Start a pomodoro session with `M-x pomodoro-mode`.
+- Stop a pomodoro session with `M-x pomodoro-mode`.
+- Move to the next work or break period with `M-x pomodoro-toggle-state`.
+
+## Customization
+
+This is a simple package that doesn't do much. That being said, you can customize some aspects of the mode:
+- `pomodoro-work-time`: the number of seconds in a work session; defaults to 1500 (25 minutes)
+- `pomodoro-break-time`: the number of seconds in a break session; defaults to 300 (5 minutes)
+- `pomodoro-work-symbol`: the string to display while in a work session; defaults to 🍅
+- `pomodoro-break-symbol`: the string to display while in a break session; defaults to 🥫
+
+These can be customized with `M-x customize-group` in the `pomodoro` group. Alternatively, you can modify your `init.el` file to set the variables with `setq`.
