 ### Maven coordinates:
 
-_Not available yet._
-
-### How to use:
-
-Firstly, you need to create the instance of `OpenWeatherMapManager` class:
-```java
-OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
-```
-where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
-
-Currently available methods:
-* `getWeatherRequester()`
-* `getForecastRequester()`
-
-#### Current weather data
-First step is retrieving `WeatherRequester` instance:
-```java
-OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
-WeatherRequester weatherRequester = openWeatherManager.getWeatherRequester();
-```
-after you are able to set preferable options(via chain methods) and execute appropriate request:
-```
-Weather weatherResponse = weatherRequester
-    .setLanguage(Language.ENGLISH)
-    .setUnitSystem(Unit.METRIC_SYSTEM)
-    .setAccuracy(Accuracy.ACCURATE)
-    .getByCityName("Minsk");
-```
-*Language*, *UnitSystem* and *Accuracy* settings will be described below.
-
-Available requests:
-* `getByCityId(String cityId)`
-* `getByCityName(String cityName)`
-* `getByCoordinates(double latitude, double longitude)`
-* `getByCoordinates(Coordinates coordinates)`
-* `getByZIPCode(String zipCode, String countryCode)`
-

+### Implemented features:
+* Current weather data
+* 5 day / 3 hour forecast
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>
+  <version>1.0</version>
+</dependency>
+```
+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:1.0'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapManager` class:
+```java
+OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently available methods:
+* `getWeatherRequester()`
+* `getForecastRequester()`
+
+#### Current weather data
+First step is retrieving `WeatherRequester` instance:
+```java
+OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
+WeatherRequester weatherRequester = openWeatherManager.getWeatherRequester();
+```
+after you are able to set preferable options(via chain methods) and execute appropriate request:
+```
+Weather weatherResponse = weatherRequester
+    .setLanguage(Language.ENGLISH)
+    .setUnitSystem(Unit.METRIC_SYSTEM)
+    .setAccuracy(Accuracy.ACCURATE)
+    .getByCityName("Minsk");
+```
+*Language*, *UnitSystem* and *Accuracy* settings will be described below.
+
+Available requests:
+* `getByCityId(String cityId)`
+* `getByCityName(String cityName)`
+* `getByCoordinates(double latitude, double longitude)`
+* `getByCoordinates(Coordinates coordinates)`
+* `getByZIPCode(String zipCode, String countryCode)`

+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:1.1'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapManager` class:
+```java
+OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently available methods:
+* `getWeatherRequester()`
+* `getHourlyForecastRequester()`
+* `getDailyForecastRequester()`
+* `getUltravioletIndexRequester()`
+* `getAirPollutionRequester()`
+
+#### Current weather data
+First step is retrieving `WeatherRequester` instance:
+```java
+OpenWeatherMapManager openWeatherManager = new OpenWeatherMapManager(API_TOKEN);
+WeatherRequester weatherRequester = openWeatherManager.getWeatherRequester();
+```
+after you are able to set preferable options(via chain methods) and execute appropriate request:
+```
+Weather weatherResponse = weatherRequester
+    .setLanguage(Language.ENGLISH)
+    .setUnitSystem(Unit.METRIC_SYSTEM)
+    .setAccuracy(Accuracy.ACCURATE)
+    .getByCityName("Minsk");
+```
+*Language*, *UnitSystem* and *Accuracy* settings will be described below.
+
+Available requests:
+* `getByCityId(String cityId)`
+* `getByCityName(String cityName)`
+* `getByCoordinates(double latitude, double longitude)`
+* `getByCoordinates(Coordinates coordinates)`
+* `getByZIPCode(String zipCode, String countryCode)`

+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._

+### Implemented features:
+* Current weather data
+* 5 day / 3-hour forecast
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>

+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:2.0.1'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data
+Examples:
+```java
+final String weatherJson = openWeatherClient
+        .currentWeather()
+        .single()
+        .byCityName("Minsk")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJSON();
+```
+
+```java
+final Weather weather = openWeatherClient
+        .currentWeather()
+        .single()
+        .byCityName("Minsk")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final List<Weather> weatherList = openWeatherClient
+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient

+### Implemented features:
+* Current weather data
+* 5 day / 3-hour forecast
+* One Call API
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>
+  <version>2.1.0</version>

+```
+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:2.1.0'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+* `oneCall()`
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data

+        .retrieve()
+        .asJSON();
+```
+
+```java

+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java

+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient

+### Implemented features:
+* Current weather data
+* 5 day / 3-hour forecast
+* One Call API
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>
+  <version>2.1.1</version>

+```
+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:2.1.1'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+* `oneCall()`
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data
+Examples:
+```java
+final String weatherJson = openWeatherClient
+        .currentWeather()

+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJSON();
+```
+
+```java
+final Weather weather = openWeatherClient
+        .currentWeather()
+        .single()
+        .byCityName("Minsk")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final List<Weather> weatherList = openWeatherClient
+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient

+### Implemented features:
+* Current weather data
+* 5 day / 3-hour forecast
+* One Call API
+* Air Pollution
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>
+  <version>2.2.0</version>
+</dependency>
+```
+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:2.2.0'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+* `oneCall()`
+* `airPollution()`
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data

+        .retrieve()
+        .asJSON();
+```
+
+```java

+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java

+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient

+### Implemented features:
+* Current weather data
+* 5 day / 3-hour forecast
+* One Call API
+* Air Pollution
+
+
+Other:
+* Request timeout settings
+
+### Maven coordinates:
+
+```xml
+<dependency>
+  <groupId>com.github.prominence</groupId>
+  <artifactId>openweathermap-api</artifactId>
+  <version>2.3.0</version>
+</dependency>
+```
+
+### Gradle coordinates:
+
+```groovy
+implementation 'com.github.prominence:openweathermap-api:2.3.0'
+```
+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+* `oneCall()`
+* `airPollution()`
+
+Also, it is possible to set timeouts for the requests on `openWeatherClient` object:
+```java
+openWeatherClient.setReadTimeout(1000);
+openWeatherClient.setConnectTimeout(1000);
+```
+Timeout settings are passed to the requesters as a copy.
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data
+Examples:
+```java
+final String weatherJson = openWeatherClient
+        .currentWeather()
+        .single()
+        .byCityName("Minsk")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJSON();
+```
+
+```java
+final Weather weather = openWeatherClient
+        .currentWeather()
+        .single()
+        .byCityName("Minsk")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final List<Weather> weatherList = openWeatherClient
+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient
+        .currentWeather()
+        .single()
+        .byZipCodeAndCountry("220015", "by")
+        .language(Language.RUSSIAN)
+        .unitSystem(UnitSystem.METRIC)
+        .retrieveAsync()
+        .asXML();
+```

+
+### How to use:
+
+Firstly, you need to create the instance of `OpenWeatherMapClient` class:
+```java
+OpenWeatherMapClient openWeatherClient = new OpenWeatherMapClient(API_TOKEN);
+```
+where `API_TOKEN` is your token([you can get it here](https://home.openweathermap.org/api_keys)) as `String`.
+
+Currently, available APIs are:
+* `currentWeather()`
+* `forecast5Day3HourStep()`
+* `oneCall()`
+* `airPollution()`
+
+Also, it is possible to set timeouts for the requests on `openWeatherClient` object:
+```java
+openWeatherClient.setReadTimeout(1000);
+openWeatherClient.setConnectTimeout(1000);
+```
+Timeout settings are passed to the requesters as a copy.
+
+Default(more or less) customization points:
+```java
+...
+// response language
+.language(Language.RUSSIAN)
+...
+// response units of measure
+.unitSystem(UnitSystem.IMPERIAL)
+...
+```
+
+Available output forms:
+* `asJava()`
+* `asJSON()`
+
+Additional output forms, available for several APIs:
+* `asXML()`
+* `asHTML()`
+
+_All response forms can be in **sync** and **async** variants._
+
+#### Current weather data
+Examples:
+```java
+final String weatherJson = openWeatherClient
+        .currentWeather()
+        .single()

+        .retrieve()
+        .asJSON();
+```
+
+```java

+        .unitSystem(UnitSystem.METRIC)
+        .retrieve()
+        .asJava();
+```
+
+```java

+        .currentWeather()
+        .multiple()
+        .byCitiesInCycle(Coordinate.of(55.5, 37.5))
+        .language(Language.GERMAN)
+        .unitSystem(UnitSystem.IMPERIAL)
+        .retrieve()
+        .asJava();
+```
+
+```java
+final CompletableFuture<String> weatherXmlFuture = openWeatherClient

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
