+### Getting groovy
+
+There are many ways to use watson
+and it is important to find what works for you.
+Below are some tips
+that we hope can make your time with watson even more efficient.
+
+Although watson supports tab completion,
+it can help to setup shell aliases to your most commonly used commands,
+for example:
+
+```shell
+alias ws='watson start'
+alias wp='watson stop'
+alias wr='watson restart'
+alias wl='watson log'
+alias we='watson edit'
+```
+
+Your workflow could be that when you start working for the day,
+you type `wl` to see if you want to restart a task
+you were working on the previous day with `wr`
+or start a new one with `ws proj +tag`.
+
+You might find yourself repeatedly switching between just a few tasks;
+in these scenario the `wr` alias is key.
+If you type it without any arguments restarts the latest entry
+(great when you continue on the same task after a break)
+and if you type `wr -2`, `wr -3`,
+it restarts older entries.
+If you mess up you can type `we` to edit the last frame,
+or `watson cancel` to abort the currently active one.
+
+Sometimes you might forget to start or stop a task,
+but don't worry,
+watson got you covered.
+The `--at` option lets you put in the time your started, restarted, or stopped a task,
+so that you can easily log past tasks,
+e.g. `wr -2 --at 10:30`, or `wp --at 12:00`.
+If you want to start a task right when the previous one ended,
+you can use `ws proj +tag -G`.
+
+There are [many useful configuration options](user-guide/configuration.md),
+including showing the currently active frame in the log output,
+setting up default tags for projects,
+printing the log to stdout instead of using a pager
+and controlling how it is formatted.
 
 We hope you will enjoy Watson!
