+# sttp module for PureConfig
+
+Adds support for [sttp](https://github.com/softwaremill/sttp). Currently supports only `com.softwaremill.sttp.Uri`.
+
+## Add pureconfig-sttp to your project
+
+In addition to [core PureConfig](https://github.com/pureconfig/pureconfig), you'll need:
+
+```scala
+libraryDependencies += "com.github.pureconfig" %% "pureconfig-sttp" % "0.10.2"
+```
+
+## Example
+
+To load an sttp `Uri` into a configuration, create a new class:
+
+```scala
+import com.softwaremill.sttp.Uri
+import com.typesafe.config.ConfigFactory.parseString
+import pureconfig._
+import pureconfig.generic.auto._
+import pureconfig.module.sttp._
+
+case class AppConfig(uri: Uri)
+```
+
+Now, we can load the configuration with the following code:
+
+```scala
+val config = parseString("""{uri: "https://sttp.readthedocs.io" }""")
+// config: com.typesafe.config.Config = Config(SimpleConfigObject({"uri":"https://sttp.readthedocs.io"}))
+
+loadConfig[AppConfig](config)
+// res0: Either[pureconfig.error.ConfigReaderFailures,AppConfig] = Right(AppConfig(https://sttp.readthedocs.io))
+```
