Tutorial Step1 Error

https://cmake.org/cmake/help/latest/guide/tutorial/A%20Basic%20Starting%20Point.html
Says

mkdir Step1_build

cd Step1_build
cmake ../Step1

The last command should be

cmake ..

Please fix this. It gives a very bad first impression.
When I first wrote code on this site, it was adding an extra dot to my double dots. It gives a very bad impression that my statements were mangled in this way.

Yo’re wrong. The tutorial says:

For example, from the command line we could navigate to the Help/guide/tutorial directory of the
CMake source code tree and create a build directory:

mkdir Step1_build

So we have:

Help/guide/tutorial
 |
 -- Step1
 |
 -- Step1_build

then:

cd Step1_build
cmake ../Step1
cmake --build .

So everything is as expected

You are correct. I was wrong. I did not follow the step
" For example, from the command line we could navigate to the Help/guide/tutorial directory of the CMake source code tree" before mkdir Step1_build.

When I unpacked cmake-3.28.0-rc3-tutorial-source.zip it did not give me the Help/guide/tutorial/ directory structure, just cmake-3.28.0-rc3-tutorial-source/Step1 etc…

In exercise 3 I had had a problem when I set my major version number to 0 (using project) and got that it wasn’t defined, ame happens if I set minor version to 0. Documentations say these can be “non-negative” integers, but it seems it only works with positive integers.
