+# Migrate pluralized request methods
+
+Migrates deprecated request methods to their pluralized versions that were deprecated in Express 4 and removed in Express 5.
+
+## Example
+
+### Migrating `req.acceptsCharset(charset)`
+
+The migration involves replacing instances of `req.acceptsCharset(charset)` with `req.acceptsCharsets(charset)`.
+
+```diff
+app.get('/', (req, res) => {
+- const charset = req.acceptsCharset('utf-8');
++ const charset = req.acceptsCharsets('utf-8');
+  res.json({ charset });
+});
+```
+### Migrating `req.acceptsEncoding(encoding)
+
+The migration involves replacing instances of `req.acceptsEncoding(encoding)` with `req.acceptsEncodings(encoding)`.
+
+```diff
+app.get('/', (req, res) => {
+- const encoding = req.acceptsEncoding('gzip');
++ const encoding = req.acceptsEncodings('gzip');
+  res.json({ encoding });
+});
+```
+
+### Migrating `req.acceptsLanguage(language)`
+
+The migration involves replacing instances of `req.acceptsLanguage(language)` with `req.acceptsLanguages(language)`.
+
+```diff
+app.get('/', (req, res) => {
+- const language = req.acceptsLanguage('en');
++ const language = req.acceptsLanguages('en');
+  res.json({ language });
+});
+```
