+# HTTP Requests
+
+You should use `env` variable to handle HTTP params. For both `get` and `post` (and others) methods, you should use `env` object.
+
+```ruby
+# Matches /hello/kemal
+  get "/hello/:name" do |env|
+    name = env.params["name"]
+    "Hello back to #{name}"
+  end
+
+  # Matches /resize?width=200&height=200
+  get "/resize" do |env|
+    width = env.params["width"]
+    height = env.params["height"]
+  end
+
+  # Easily access JSON payload from the params.
+  # The request content type needs to be application/json
+  # The payload
+  # {"name": "Serdar", "likes": ["Ruby", "Crystal"]}
+  post "/json_params" do |env|
+    name = env.params["name"] as String
+    likes = env.params["likes"] as Array
+    "#{name} likes #{likes.each.join(',')}"
+  end
+
+  # Set the content as application/json and return JSON
+  get "/user.json" do |env|
+    kemal = {name: "Kemal", language: "Crystal"}
+    env.content_type = "application/json"
+    kemal.to_json
+  end
+
+  # Add headers to your response
+  get "/headers" do |env|
+    env.add_header "Accept-Language", "tr"
+    env.add_header "Authorization", "Token 12345"
+  end
+```
