+## Tips
+
+### Searching commits
+
+You can use `git log --grep` to find a commit that matches a specific keyword.
+
+### Restoring files
+
+Knowing a commit hash, you can view the tree related to that commit by calling `git show HASH:`. You can access any file in that tree by adding its relative path after the colon, for example, `git show HASH:path/to/file`. Thus, to restore a file, redirect the standard output somewhere, for example, `git show HASH:path/to/file > path/to/file`.
+
+To restore all files in the current working tree, run `git restore :/`.
