+Node.js v18 is no longer supported.
+
+### When using global fetch with Node.js v22, v23, v24, undici v6 should be installed.
+
+The global fetch built-in to Node.js v20, v22, and v23 is undici v6.
+
+So, you should install undici v6 and then load `CookieAgent` from `http-cookie-agent/undici/v6`.
+
+```diff
+- import { CookieAgent } from 'http-cookie-agent/undici';
++ import { CookieAgent } from 'http-cookie-agent/undici/v6';
+```
+
+### undici v7 supports
+
+When using `CookieClient` or `createCookieClient`, you should replace it with the compose method.
+
+```diff
+- import { CookieClient } from 'http-cookie-agent/undici';
++ import { cookie } from 'http-cookie-agent/undici';
++ import { Client } from 'undici';
+
+- const client = new CookieClient('https://example.com', { cookie: { jar } });
++ const client = new Client('https://example.com').compose(cookie({ jar }));
+```
+
+When using `CookieAgent`, you can use the code as is.
+If you want to redirect like undici v6, you can add a "redirect" feature with the compose method.
+
+```typescript
+import { CookieAgent } from 'http-cookie-agent/undici';
+import { CookieJar } from 'tough-cookie';
+import { fetch, interceptors } from 'undici';
+
+const jar = new CookieJar();
+const agent = new CookieAgent({ cookies: { jar } }).compose(interceptors.redirect());
+
+await fetch('https://example.com', { dispatcher: agent, maxRedirections: 3 });
+```
