+# curl Android
+
+curl static library prefab for android
+
+## Integration
+
+Gradle:
+
+```gradle
+implementation 'io.github.vvb2060.ndk:curl:7.72.0'
+```
+
+This library is [Prefab](https://google.github.io/prefab/), so you will need to enable it in your project (Android Gradle Plugin 4.1+):
+
+```gradle
+android {
+    ...
+    buildFeatures {
+        ...
+        prefab true
+    }
+}
+```
+
+## Usage
+
+### ndk-build
+
+you can use `curl_static` in your `Android.mk`. 
+For example, if your application defines `libapp.so` and it uses `curl_static`, your `Android.mk` file should include the following:
+
+```makefile
+include $(CLEAR_VARS)
+LOCAL_MODULE           := app
+LOCAL_SRC_FILES        := app.cpp
+LOCAL_STATIC_LIBRARIES := curl_static
+include $(BUILD_SHARED_LIBRARY)
+
+# If you don't need your project to build with NDKs older than r21, you can omit
+# this block.
+ifneq ($(call ndk-major-at-least,21),true)
+    $(call import-add-path,$(NDK_GRADLE_INJECTED_IMPORT_PATH))
+endif
+
+$(call import-module,prefab/curl)
+```
+
+### CMake
+
+you can use `curl_static` in your `CMakeLists.txt`. 
+For example, if your application defines `libapp.so` and it uses `curl_static`, your `CMakeLists.txt` file should include the following:
+
+```cmake
+add_library(app SHARED app.cpp)
+
+# Add these two lines.
+find_package(curl REQUIRED CONFIG)
+target_link_libraries(app curl::curl_static)
+```
