+   - remote
+      git remote -v                     list remotes verbose (with URLs)
+      git remote show [-n] <remote>     list info for <remote> (like remote HEAD, remote branches, tracking mapping)
+                                        -n show available info without contacting remote (offline mode)
+
+   - branching
+      git branch [-a]               list available branches; -a to include remote branches
+      git branch -vv                list branch & annotate with head sha1 & remote tracking branch
+      git branch <bname>            create branch with name <bname>
+      git checkout <bname>          switch to branch with name <bname>
+      git push -u origin <rbname>   push branch to origin (or other remote), and setup <rbname> as tracking branch
+
+   - resetting
+      git reset [type] <ref|commit>
+         type:
+            --mixed              resets index, but not working tree
+            --hard               matches the working tree and index to that of the tree being switched to
+                                 any changes to tracked files in the working tree since <commit> are lost
+      git reset HEAD <file>      remove file from staging
+      git reset --soft HEAD~1    delete most recent commit but keep work
+      git reset --hard HEAD~1    delete most recent commit and delete work
+
+   - tags
+      git tag -a <tname> -m "descr"          creates an annotated tag (full object containing tagger, date, ...)
+      git tag -l                             list available tags
+      git checkout tag/<tname>               checkout specific tag
+      git checkout tag/<tname> -b <bname>    checkout specific tag in a new branch
+
+   - diff
+      git diff HEAD:<fname> origin/HEAD:<fname>     diff files for different refs
+      git diff -U$(wc -l <fname>) <fname>           shows complete file with diffs instead of usual diff snippets
+
+   - log
+      git log --oneline         shows log in single line per commit -> alias for '--pretty=oneline --abbrev-commit'
+      git log --graph           text based graph of commit history
+      git log --decorate        decorate log with REFs
+
+   - patching
+      git format-patch <opt> <since>/<revision range>
+         opt:
+            -N                  use [PATCH] even with multiple patches (default is [PATCH n/m]
+                                where n is current commit num and m is total commit num in patch)
+            --start-number <n>  start output file generation with <n> as start number instead '1'
+         since spcifier:
+            -3                  e.g: create a patch from last three commits
+            <comit hash>        create patch with commits starting after <comit hash>
+
+      git am <patch>            apply patch and create a commit for it
+
+      git apply --stat <PATCH>      see which files the patch would change
+      git apply --check <PATCH>     see if the patch can be applied cleanly
+      git apply <PATCH>             apply the patch locally without creating a commit
+
+      # eg: generate patches for each commit from initial commit on
+      git format-patch -N $(git rev-list --max-parents=0 HEAD)
+
+     # generate single patch file from a certain commit/ref
+     git format-patch <COMMIT/REF> --stdout > my-patch.patch

+   - <revision range>
+      HEAD                                      last commit
+      HEAD~1                                    last commit-1
+      HEAD~N                                    last commit-N (linear backwards when in tree structure, check difference between HEAD^ and HEAD~)
+      git rev-list --max-parents=0 HEAD         first commit
