+**Note**: Some Fediverse software (Akkoma, Mitra) use Content Security Policy configuration which disallows the usage of inline styles, which are used by pl-fe for color schemes. [Mangane README](https://github.com/BDX-town/Mangane/) suggests using server configuration to override the default CSP header:
+>
+> Here is an example configuration for nginx:
+> ```
+> # add style-src for mangane
+> proxy_hide_header Content-Security-Policy;
+> add_header Content-Security-Policy "upgrade-insecure-requests;script-src 'self';connect-src 'self' blob: https://example.com wss://example.com;media-src 'self' https:;img-src 'self' data: blob: https:;default-src 'none';base-uri 'self';frame-ancestors 'none';style-src 'self' 'unsafe-inline';font-src 'self';manifest-src 'self';" always;
+> ```
+> *Please replace https://example.com with your own domain*
