+Clang-format Guide and Tips
+===================
+
+This wiki page describes how to set up clang-format tool as a part of your worklow. Running the command given in the description will fix clang-format problem.
+
+
+- Add `tools/lint/git-clang-format-13 ` to your `$PATH`. Once its added to your `$PATH`, running `git clang-format` will invoke it.
+```bash
+git clang-format
+```
+
+
+- To reformat chosen file just do: 
+```bash
+# `_FILE_NAME_` is the name of a file to be formatted.
+# i - apply edits to files instead of displaying a diff
+clang-format -i _FILE_NAME_
+```
+
+- To reformat all the lines in the latest git commit, just do: 
+```bash
+git diff -U0 --no-color HEAD^ | clang-format-diff.py -i -p1
+
+```
+
+- If you want to apply clang-format only to the changed lines in each commit do the following:
+```bash
+# If it's a child of origin/master, the following command-line could be used:
+# If you want to run this command on another brnach, then origin/master needs to be replaced.
+export COMMIT_SHA=$(git rev-list --ancestry-path origin/master..HEAD | tail -n 1)
+
+git filter-branch --tree-filter 'git-clang-format $COMMIT_SHA^' -- $COMMIT_SHA..HEAD
+```
