+`--rm` removes the container after running, `-it` makes it interactive, `-v ~/.local/share/.gtt/:/home/gtt/.local/share/.gtt ` mounts your gtt configuration directory in the gtt user home directory inside the container. For example, to run a report for a particular user with a date range:

 I highly recommend creating an alias and adding it to your `bashrc`:
 
 ```shell
-echo "alias gtt='docker run --rm -it -v ~:/root -v $(pwd):/pwd kriskbx/gitlab-time-tracker'" >>~/.bashrc
+echo "alias gtt='docker run --rm -it -v -v ~/.local/share/.gtt/:/home/gtt/.local/share/.gtt kriskbx/gitlab-time-tracker'" >>~/.bashrc
 ```
 
 Now you can simply write `gtt` instead of the bulky Docker command before. Try it out: `gtt --help`
