 ====== Git Basics ======
-Git is a complicated tool to use, if you don't use it on a very regular basis.
-I prefer using Graphic interfaces that help a lot with git management like in Atom, but here is a recap of basic commands so I remember them when I need.

+===== Branches =====
 Switch branch (option create)
 <code>
-git checkout branch_name
+git switch branch_name
-git checkout -b create_branch_name
+git switch -c create_branch_name
 </code>
-==== Atom, Git and Rust ====
+(''git switch'' needs git 2.23 or later; on older versions use ''git checkout'' and ''git checkout -b''.)
+===== Git and Rust =====
 When you create a new Rust project using Cargo it automatically initializes a local git repository.
@@ Line 30: / Line 28: @@
 <code>
+cd existing_folder
+git init # Skip if in a Rust project created with cargo, git is already initialized
 git remote add origin <remote_repo_url>
-git push --all origin
+git add . # required
+git commit -m "Initial commit" # Feel free to change the message
+git push -u origin main # This is what actually pushes (use master if your default branch is still called master)
 </code>
+Git will ask you to authenticate as the owner of the remote repository. GitHub no longer accepts account passwords for git: use a personal access token (entered as the password) or an SSH key (with an SSH remote URL).
+Most modern editors (VS Code, Zed...) detect the git repository automatically when the project root folder is opened directly.
 If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:
 <code>
 git push --all --set-upstream origin
 </code>
-Atom has a built-in git feature that will automatically detect git repositories and has a useful GUI. To use it, your project root folder **must be directly** in the project tree manager. It cannot be in a sub-directory or Atom will **not** autodetect the git repository.
+===== Branching =====
+To get a branch that exists on the remote repository, fetch the remote data then switch to the branch:
+<code>
+git fetch origin
+git switch <name-of-branch>
+</code>
+''git fetch'' downloads everything from ''origin'' without changing your files. ''git switch'' then creates a local branch with the same name that automatically tracks the remote one.
