-If you're using Flake8, you can bump `max-line-length` to 88 and mostly forget about it.
-However, it's better if you use [Bugbear](https://github.com/PyCQA/flake8-bugbear)'s
-B950 warning instead of E501, and bump the max line length to 88 (or the `--line-length`
-you used for black), which will align more with black's _"try to respect
-`--line-length`, but don't become crazy if you can't"_. You'd do it like this:
-
-```ini
-[flake8]
-max-line-length = 88
-...
-select = C,E,F,W,B,B950
-extend-ignore = E203, E501
-```
+#### Flake8

 
 

-Explanation of why E203 is disabled can be found further in this documentation. And if
-you're curious about the reasoning behind B950,
-[Bugbear's documentation](https://github.com/PyCQA/flake8-bugbear#opinionated-warnings)
-explains it. The tl;dr is "it's like highway speed limits, we won't bother you if you
-overdo it by a few km/h".
+If you use Flake8, you have a few options:

 
 

-**If you're looking for a minimal, black-compatible flake8 configuration:**
+1. Recommended is using [Bugbear](https://github.com/PyCQA/flake8-bugbear) and enabling
+   its B950 check instead of using Flake8's E501, because it aligns with Black's 10%
+   rule. Install Bugbear and use the following config:

 
 

-```ini
-[flake8]
-max-line-length = 88
-extend-ignore = E203
-```
+   ```ini
+   [flake8]
+   max-line-length = 80
+   ...
+   select = C,E,F,W,B,B950
+   extend-ignore = E203, E501
+   ```
+
+   The rationale for E950 is explained in
+   [Bugbear's documentation](https://github.com/PyCQA/flake8-bugbear#opinionated-warnings).
+
+2. For a minimally compatible config:
+
+   ```ini
+   [flake8]
+   max-line-length = 88
+   extend-ignore = E203
+   ```
+
+An explanation of why E203 is disabled can be found in the [Slices section](#slices) of
+this page.
