Errata

The single sentence of the third paragraph on page 7 ends "then you should continue ono the next section to install an up-to-date version of Git on your computer." That should probably be "... continue on to the next section ..." [continue ono -> continue on to]

Note from the Author or Editor:
Yes, you're absolutely right, we will have to fix this. Thank you for bringing this to our attention! (-:

The Follow Along 1-14 shows the following prompt and command:

$rainbow $ git config --global --list

The initial part of the prompt is meant to be the user's current working directory. Previous Follow Alongs asked the user to create directories 'desktop' and 'rainbow'. Therefore, the '$' before rainbow looks like a minor mistake. The prompt and command should read:

rainbow $ git config --global --list

Note from the Author or Editor:
The reader is right. This is a mistake. It should be changed to:
rainbow $ git config --global --list

Figure 2-1 shows the contents of the '.git' local repository directory immediately after issuing the 'git init -b main' command. The first file is given as '.config'. However, on my system, and in every cloned repo I have examined, the file is 'config', without the initial 'dot'. So, I believe that first file should be 'config' rather than '.config'.

Note from the Author or Editor:
Yes, the reader is right, the file should be config not .config.

The NOTE begins: "There are times where you can be on a commit ...". Given that the sentence begins "There are times ..." I would expect the subordinating conjunction to reflect a temporal reference rather than a spatial one. Although the sentence is understandable as written, I believe it would be (slightly) better as "There are times when you can be on a commit ..." [where -> when].

(Yes, this is rather picky. No doubt opinions may differ.)

Note from the Author or Editor:
The reader is once again correct. Let's use the correction suggested by the reader.

"There are times when you can be on a commit...."

The final sentence of the paragraph ends "... once called chapter_five_approach_a and one called chapter_five_approach_b." That should be "... one called chapter_five_approach_a and one called ..." [once -> one]

Note from the Author or Editor:
Yes, the reader is correct, the word "once" should be changed to "one".

The last sentence of the paragraph begins:

At the time of cloning the remote repository URL was associated with a shortname in the local repository, ...

It would help readability by adding a comma after "At the time of cloning". Otherwise, "the remote repository URL" is likely to be taken as the direct object of the participle "cloning" which then leads to an inability to parse "was associated ...". This forces the reader to backtrack and try to parse the sentence again. Using a comma to mark off the initial temporal adverbial phrase allows the reader to treat "the remote repository URL" as the sentence's subject and smoothly parse the remainder of the sentence.

(Yes, I am being picky again. However, if I had a problem with this sentence, it is highly likely that other readers have had a similar experience.)

Note from the Author or Editor:
The reader is right, let's fix this as they recommended.

The first sentence begins: "Suppose I work on chapters 1, 2, and 3, of my book, ..." I would say there is an extraneous comma after '3' so I would suggest changing it to "Suppose I work on chapters 1, 2, and 3 of my book, ..." See the next sentence for a similar phrasing which does not have the extra comma.

Note from the Author or Editor:
Let's change this as well as the reader recommends.

The paragraph begins: "InExample Book Project 12-11, ...". That should be "In Example Book Project 12-11, ..." [InExample -> In Example].

Yes, trivial, but if someone is going to update the text at all they might as well update such trivialities.

Note from the Author or Editor:
The reader is right, let's fix this.
