+}
+```
+
+## Middleware Configuration
+
+### Session
+
+**Macaron:**
+```go
+m.Use(session.Sessioner(session.Options{
+    Provider:       "memory",
+    ProviderConfig: "",
+    CookieName:     "session_id",
+    CookiePath:     "/",
+    Gclifetime:     3600,
+    Maxlifetime:    3600,
+}))
+```
+
+**Flamego:**
+```go
+f.Use(session.Sessioner(session.Options{
+    Config: session.MemoryConfig{
+        GCInterval: 3600,
+    },
+    Cookie: session.CookieOptions{
+        Name:   "session_id",
+        Path:   "/",
+        MaxAge: 3600,
+    },
+}))
+```
+
+### CSRF
+
+**Macaron:**
+```go
+m.Use(csrf.Csrfer(csrf.Options{
+    Secret:     "secret-key",
+    Cookie:     "_csrf",
+    CookiePath: "/",
+    SetCookie:  true,
+    Secure:     false,
+}))
+```
+
+**Flamego:**
+```go
+f.Use(csrf.Csrfer(csrf.Options{
+    Secret:     "secret-key",
+    Cookie:     "_csrf",
+    CookiePath: "/",
+    Secure:     false,
+}))
+```
+
+### Cache
+
+**Macaron:**
+```go
+m.Use(cache.Cacher(cache.Options{
+    Adapter:       "memory",
+    AdapterConfig: "",
+    Interval:      60,
+}))
+```
+
+**Flamego:**
+```go
+f.Use(cache.Cacher(cache.Options{
+    Config: cache.MemoryConfig{
+        GCInterval: 60,
+    },
+}))
+```
+
+### Template
+
+**Macaron:**
+```go
+m.Use(macaron.Renderer(macaron.RenderOptions{
+    Directory: "templates",
+    Funcs:     template.FuncMap(),
+}))
+```
+
+**Flamego:**
+```go
+f.Use(template.Templater(template.Options{
+    Directory: "templates",
+    FuncMaps:  []template.FuncMap{template.FuncMap()},
+}))
+```
+
+### i18n
+
+**Macaron:**
+```go
+m.Use(i18n.I18n(i18n.Options{
+    SubURL:      "/",
+    Langs:       []string{"en-US", "zh-CN"},
+    Names:       []string{"English", "简体中文"},
+    DefaultLang: "en-US",
+}))
+```
+
+**Flamego:**
+```go
+f.Use(i18n.I18n(i18n.Options{
+    URLPrefix:       "/",
+    Languages:       []string{"en-US", "zh-CN"},
+    Names:           []string{"English", "简体中文"},
+    DefaultLanguage: "en-US",
+}))
+```
+
+## Common Patterns
+
+### Pattern: Get User by Username
+
+**Macaron:**
+```go
+func UserProfile(c *context.Context) {
+    username := c.Params(":username")
+    user, err := database.GetUserByName(username)
+    if err != nil {
+        c.NotFoundOrError(err, "get user")
+        return
+    }
+    c.Data["User"] = user
+    c.HTML(200, "user/profile")
+}
+```
+
+**Flamego:**
+```go
+func UserProfile(c *context.Context, t template.Template, data template.Data) {
+    username := c.Param("username")
+    user, err := database.GetUserByName(username)
+    if err != nil {
+        c.NotFoundOrError(err, "get user")
+        return
+    }
+    data["User"] = user
+    t.HTML(200, "user/profile")
+}
+```
+
+### Pattern: Form Submission
+
+**Macaron:**
+```go
+// Form struct
+type CreateRepoForm struct {
+    Name string `form:"name" binding:"Required;AlphaDashDot"`
+}
+
+// Route
+m.Post("/repo/create", binding.Bind(CreateRepoForm{}), CreateRepoPost)
+
+// Handler
+func CreateRepoPost(c *context.Context, form CreateRepoForm) {
+    if c.HasError() {
+        c.RenderWithErr(c.GetErrMsg(), "repo/create", &form)
+        return
+    }
+    // Create repo...
+    c.Redirect("/")
+}
+```
+
+**Flamego:**
+```go
+// Form struct
+type CreateRepoForm struct {
+    Name string `form:"name" validate:"required,alphaDashDot"`
+}
+
+// Route
+f.Post("/repo/create", binding.Form(CreateRepoForm{}), CreateRepoPost)
+
+// Handler
+func CreateRepoPost(c *context.Context, form CreateRepoForm, t template.Template, data template.Data) {
+    if c.HasError() {
+        c.RenderWithErr(c.GetErrMsg(), "repo/create", &form, t, data)
+        return
+    }
+    // Create repo...
+    c.Redirect("/")
+}
+```
+
+### Pattern: JSON API
+
+**Macaron:**
+```go
+func APIHandler(c *context.APIContext) {
+    data := map[string]any{
+        "id":   123,
+        "name": "example",
+    }
+    c.JSON(200, data)
+}
+```
+
+**Flamego:**
+```go
+func APIHandler(c *context.APIContext) {
+    data := map[string]any{
+        "id":   123,
+        "name": "example",
+    }
+    
+    c.ResponseWriter().Header().Set("Content-Type", "application/json")
+    c.ResponseWriter().WriteHeader(200)
+    json.NewEncoder(c.ResponseWriter()).Encode(data)
+}
+
+// Or create helper method on APIContext
+func (c *APIContext) JSON(status int, v any) error {
+    c.ResponseWriter().Header().Set("Content-Type", "application/json")
+    c.ResponseWriter().WriteHeader(status)
+    return json.NewEncoder(c.ResponseWriter()).Encode(v)
+}
+```
+
+### Pattern: Middleware Chain
+
+**Macaron:**
+```go
+m.Group("/repo", func() {
+    m.Get("/create", repo.Create)
+    m.Post("/create", binding.Bind(form.CreateRepo{}), repo.CreatePost)
+}, reqSignIn, context.RepoAssignment())
+```
+
+**Flamego:**
+```go
+f.Group("/repo", func() {
+    f.Get("/create", repo.Create)
+    f.Post("/create", binding.Form(form.CreateRepo{}), repo.CreatePost)
+}, reqSignIn, context.RepoAssignment())
+```
+
+## Error Handling
+
+### Not Found
+
+**Macaron:**
+```go
+func Handler(c *context.Context) {
+    user, err := getUser()
+    if err != nil {
+        if isNotFound(err) {
+            c.NotFound()
+            return
+        }
+        c.Error(err, "get user")
+        return
+    }
+}
+```
+
+**Flamego:**
+```go
+func Handler(c *context.Context) {
+    user, err := getUser()
+    if err != nil {
+        if isNotFound(err) {
+            c.NotFound()
+            return
+        }
+        c.Error(err, "get user")
+        return
+    }
+}
+```
+
+## Testing
+
+### Mock Context
+
+**Macaron:**
+```go
+import "gopkg.in/macaron.v1"
+
+func TestHandler(t *testing.T) {
+    m := macaron.New()
+    req, _ := http.NewRequest("GET", "/", nil)
+    resp := httptest.NewRecorder()
+    m.ServeHTTP(resp, req)
+}
+```
+
+**Flamego:**
+```go
+import "github.com/flamego/flamego"
+
+func TestHandler(t *testing.T) {
+    f := flamego.New()
+    req, _ := http.NewRequest("GET", "/", nil)
+    resp := httptest.NewRecorder()
+    f.ServeHTTP(resp, req)
+}
+```
+
+## Migration Checklist (Quick)
+
+- [ ] Update imports
+- [ ] Change `:param` → `<param>` in routes
+- [ ] Change `macaron.Handler` → `flamego.Handler`
+- [ ] Change `*macaron.Context` → `flamego.Context`
+- [ ] Change `c.Params(":name")` → `c.Param("name")`
+- [ ] Change `c.Resp` → `c.ResponseWriter()`
+- [ ] Change `c.Req` → `c.Request()`
+- [ ] Change `session.Store` → `session.Session`
+- [ ] Change `x.GetToken()` → `x.Token()`
+- [ ] Change `cache.Put()` → `cache.Set()`
+- [ ] Add template parameters to handlers
+- [ ] Update form validation tags
+- [ ] Test everything!
+
+## Common Pitfalls
+
+| Issue | Solution |
+|-------|----------|
+| Forgot to remove `:` from param name | Use `c.Param("name")` not `c.Param(":name")` |
+| Template not rendering | Add `template.Template` and `template.Data` to handler |
+| Session not working | Changed interface from `Store` to `Session` |
+| CSRF validation fails | Use `Token()` not `GetToken()` |
+| Cache not working | Use `Set()` not `Put()` |
+| Form validation errors | Update tags: `binding` → `validate` |
+| Context methods fail | Use methods not fields: `c.ResponseWriter()` not `c.Resp` |
+
+## Performance Notes
+
+### Flamego Advantages
+
+1. **O(1) static route lookup** - Faster than Macaron's tree
+2. **Better regex handling** - Compiled patterns cached
+3. **Reduced allocations** - More efficient memory usage
+4. **Faster middleware chain** - Optimized injection
+
+### Expected Improvements
+
+- 10-30% faster route matching for static routes
+- 5-15% faster overall request handling
+- Slightly lower memory usage
+- Better scalability under load
