ok thanks.. I know what happened.. I renamed all the course lessons and the documentation has not yet been updated so the link looks on the old file.
I have triggered the rebuilding of the documentation.. either you wait ~ one hour or directly pick up the file on GitHub : https://github.com/sylvaticus/SPMLJ/tree/main/lessonsSources/01_-_JULIA1_-_Basic_Julia_programming
Still, the best would be to clone the repository.. if you really can't use git for some reason, just download the zip containing the whole repository and extract it on your pc.
