+## Signatures
+
+```go
+func New(config ...Config) fiber.Handler
+```
+
+## Examples
+
+First import the middleware from Fiber,
+
+```go
+import (
+  "github.com/gofiber/fiber/v2"
+  "github.com/gofiber/fiber/v2/middleware/envvar"
+)
+```
+
+Then create a Fiber app with `app := fiber.New()`.
+
+**Note**: You need to provide a path to use envvar middleware.
+
+### Default Config
+
+```go
+app.Use("/expose/envvars", envvar.New())
+```
+
+### Custom Config
+
+```go
+app.Use("/expose/envvars", envvar.New(envvar.Config{
+    ExportVars:  map[string]string{"testKey": "", "testDefaultKey": "testDefaultVal"},
+    ExcludeVars: map[string]string{"excludeKey": ""}}
+}))
+```
+
+### Response
+
+Http response contract:
+```
+{
+  "vars": {
+    "someEnvVariable": "someValue",
+    "anotherEnvVariable": "anotherValue",
+  }
+}
+
+```
+
+## Config
+
+```go
+// Config defines the config for middleware.
+type Config struct {
+    // ExportVars specifies the environment variables that should export
+    ExportVars map[string]string
+    // ExcludeVars specifies the environment variables that should not export
+    ExcludeVars map[string]string
+}
+
+```
+
+## Default Config
+
+```go
+Config{}
+```
