[description]

|
|
Note that there are two options to "travel to the end of a timeline":
|
|
|
|
First, you can directly travel to the commit, like we've done it before.
|
|
|
|
And second, you can travel to the branch label. In this case, when you make a new commit, the branch will grow with you, and still point at the end of the timeline!
|
|
|
|
[cli]
|
|
|
|
To travel to a branch, type `git checkout name_of_the_branch`.
|
|
|
|
And to travel to the last commit, type `git checkout --detach name_of_the_branch`.

echo "You go to the birthday party!" >> you
