 ### Strings
 
-*Black* prefers double quotes (`"` and `"""`), but only if this does not
-result in more escaping. It will remove escape sequences as necessary as
-part of moving to the other type of quote. This applies to all kinds of
-prefixed strings, including *raw-strings* (`r""`), *byte literals* (`b""`),
-and *formatted strings* (`f""`). The approach above strikes a good balance
-between consistency and legibility.
+*Black* prefers double quotes (`"` and `"""`) over single quotes (`'`
+and `'''`).  It will replace the latter with the former as long as it
+does not result in more backslash escapes than before.
+
+The main reason to standardize on a single form of quotes is aesthetics.
+Having one kind of quotes everywhere reduces reader distraction.
+It will also enable a future version of *Black* to merge consecutive
+string literals that ended up on the same line (see
+[#26](https://github.com/ambv/black/issues/26) for details).
+
+Why settle on double quotes?  They anticipate apostrophes in English
+text.  They match the docstring standard described in PEP 257.  An
+empty string in double quotes (`""`) is impossible to confuse with
+a one double-quote regardless of fonts and syntax highlighting used.
+On top of this, double quotes for strings are consistent with C which
+Python interacts a lot with.
+
+On certain keyboard layouts like US English, typing single quotes is
+a bit easier than double quotes.  The latter requires use of the Shift
+key.  My recommendation here is to keep using whatever is faster to type
+and let *Black* handle the transformation.

+## Version control integration
+
+Use [pre-commit](https://pre-commit.com/). Once you [have it
+installed](https://pre-commit.com/#install), add this to the
+`.pre-commit-config.yaml` in your repository:
+```yaml
+repos:
+-   repo: https://github.com/ambv/black
+    rev: stable
+    hooks:
+    - id: black
+      args: [--line-length=88, --safe]
+      python_version: python3.6
+```
+Then run `pre-commit install` and you're ready to go.
+
+`args` in the above config is optional but shows you how you can change
+the line length if you really need to.  If you're already using Python
+3.7, switch the `python_version` accordingly. Finally, `stable` is a tag
+that is pinned to the latest release on PyPI.  If you'd rather run on
+master, this is also an option.
