+```
+
+## Branching
+```markdown
+  git branch [-a] ................ list available branches; -a to include

+```
+
+## Diff
+```markdown

+  git diff -U$(wc -l <fname>) <fname> ......... shows complete file with diffs

+## Patching
+```markdown
+  git format-patch <opt> <since>/<revision range>
+    opt:
+      -N ................... use [PATCH] instead [PATCH n/m] in subject when

+      -3 .................. e.g: create a patch from last three commits
+      <commit hash> ....... create patch with commits starting after <commit 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

+## Submodules
+```markdown

+                                              origin/HEAD or a branch specified
+                                              for the submodule

+```
+
+## Revision Specifier
+```markdown
+  HEAD ........ last commit
+  HEAD~1 ...... last commit-1
+  HEAD~N ...... last commit-N (linear backwards when in tree structure, check

+  git rev-list --max-parents=0 HEAD ........... first commit
+```
