+# Storage Management
+
+Manage cookies, localStorage, sessionStorage, and browser storage state.
+
+## Storage State
+
+Save and restore complete browser state including cookies and storage.
+
+### Save Storage State
+
+```bash
+# Save to auto-generated filename (storage-state-{timestamp}.json)
+playwright-cli state-save
+
+# Save to specific filename
+playwright-cli state-save my-auth-state.json
+```
+
+### Restore Storage State
+
+```bash
+# Load storage state from file
+playwright-cli state-load my-auth-state.json
+
+# Reload page to apply cookies
+playwright-cli open https://example.com
+```
+
+### Storage State File Format
+
+The saved file contains:
+
+```json
+{
+  "cookies": [
+    {
+      "name": "session_id",
+      "value": "abc123",
+      "domain": "example.com",
+      "path": "/",
+      "expires": 1735689600,
+      "httpOnly": true,
+      "secure": true,
+      "sameSite": "Lax"
+    }
+  ],
+  "origins": [
+    {
+      "origin": "https://example.com",
+      "localStorage": [
+        { "name": "theme", "value": "dark" },
+        { "name": "user_id", "value": "12345" }
+      ]
+    }
+  ]
+}
+```
+
+## Cookies
+
+### List All Cookies
+
+```bash
+playwright-cli cookie-list
+```
+
+### Filter Cookies by Domain
+
+```bash
+playwright-cli cookie-list --domain=example.com
+```
+
+### Filter Cookies by Path
+
+```bash
+playwright-cli cookie-list --path=/api
+```
+
+### Get Specific Cookie
+
+```bash
+playwright-cli cookie-get session_id
+```
+
+### Set a Cookie
+
+```bash
+# Basic cookie
+playwright-cli cookie-set session abc123
+
+# Cookie with options
+playwright-cli cookie-set session abc123 --domain=example.com --path=/ --httpOnly --secure --sameSite=Lax
+
+# Cookie with expiration (Unix timestamp)
+playwright-cli cookie-set remember_me token123 --expires=1735689600
+```
+
+### Delete a Cookie
+
+```bash
+playwright-cli cookie-delete session_id
+```
+
+### Clear All Cookies
+
+```bash
+playwright-cli cookie-clear
+```
+
+### Advanced: Multiple Cookies or Custom Options
+
+For complex scenarios like adding multiple cookies at once, use `run-code`:
+
+```bash
+playwright-cli run-code "async page => {
+  await page.context().addCookies([
+    { name: 'session_id', value: 'sess_abc123', domain: 'example.com', path: '/', httpOnly: true },
+    { name: 'preferences', value: JSON.stringify({ theme: 'dark' }), domain: 'example.com', path: '/' }
+  ]);
+}"
+```
+
+## Local Storage
+
+### List All localStorage Items
+
+```bash
+playwright-cli localstorage-list
+```
+
+### Get Single Value
+
+```bash
+playwright-cli localstorage-get token
+```
+
+### Set Value
+
+```bash
+playwright-cli localstorage-set theme dark
+```
+
+### Set JSON Value
+
+```bash
+playwright-cli localstorage-set user_settings '{"theme":"dark","language":"en"}'
+```
+
+### Delete Single Item
+
+```bash
+playwright-cli localstorage-delete token
+```
+
+### Clear All localStorage
+
+```bash
+playwright-cli localstorage-clear
+```
+
+### Advanced: Multiple Operations
+
+For complex scenarios like setting multiple values at once, use `run-code`:
+
+```bash
+playwright-cli run-code "async page => {
+  await page.evaluate(() => {
+    localStorage.setItem('token', 'jwt_abc123');
+    localStorage.setItem('user_id', '12345');
+    localStorage.setItem('expires_at', Date.now() + 3600000);
+  });
+}"
+```
+
+## Session Storage
+
+### List All sessionStorage Items
+
+```bash
+playwright-cli sessionstorage-list
+```
+
+### Get Single Value
+
+```bash
+playwright-cli sessionstorage-get form_data
+```
+
+### Set Value
+
+```bash
+playwright-cli sessionstorage-set step 3
+```
+
+### Delete Single Item
+
+```bash
+playwright-cli sessionstorage-delete step
+```
+
+### Clear sessionStorage
+
+```bash
+playwright-cli sessionstorage-clear
+```
+
+## IndexedDB
+
+### List Databases
+
+```bash
+playwright-cli run-code "async page => {
+  return await page.evaluate(async () => {
+    const databases = await indexedDB.databases();
+    return databases;
+  });
+}"
+```
+
+### Delete Database
+
+```bash
+playwright-cli run-code "async page => {
+  await page.evaluate(() => {
+    indexedDB.deleteDatabase('myDatabase');
+  });
+}"
+```
+
+## Common Patterns
+
+### Authentication State Reuse
+
+```bash
+# Step 1: Login and save state
+playwright-cli open https://app.example.com/login
+playwright-cli snapshot
+playwright-cli fill e1 "user@example.com"
+playwright-cli fill e2 "password123"
+playwright-cli click e3
+
+# Save the authenticated state
+playwright-cli state-save auth.json
+
+# Step 2: Later, restore state and skip login
+playwright-cli state-load auth.json
+playwright-cli open https://app.example.com/dashboard
+# Already logged in!
+```
+
+### Save and Restore Roundtrip
+
+```bash
+# Set up authentication state
+playwright-cli open https://example.com
+playwright-cli eval "() => { document.cookie = 'session=abc123'; localStorage.setItem('user', 'john'); }"
+
+# Save state to file
+playwright-cli state-save my-session.json
+
+# ... later, in a new session ...
+
+# Restore state
+playwright-cli state-load my-session.json
+playwright-cli open https://example.com
+# Cookies and localStorage are restored!
+```
+
+## Security Notes
+
+- Never commit storage state files containing auth tokens
+- Add `*.auth-state.json` to `.gitignore`
+- Delete state files after automation completes
+- Use environment variables for sensitive data
+- By default, sessions run in-memory mode which is safer for sensitive operations
