-
-## Quick Start
-
-1. Install the libraries and dependencies according to [Installation of the library](#installation-of-the-library)
-
-2. Connect the SHT4X sensor to your Arduino as explained in [Sensor wiring](#sensor-wiring)
-
-3. Open the `exampleUsage` sample project within the Arduino IDE:
-
-   `File` ➔ `Examples` ➔ `Sensirion I2C SHT4X` ➔ `exampleUsage`
-
-  
-   The provided example is working with a SHT40, I²C address 0x44.
-   In order to use the code with another product or I²C address you need to change it in the code of `exampleUsage`. 
-   You find the list with pre-defined addresses in `src/SensirionI2CSht4x.h`.
-
-
-5. Click the `Upload` button in the Arduino IDE or `Sketch` ➔ `Upload`
-
-4. When the upload process has finished, open the `Serial Monitor` or `Serial
-   Plotter` via the `Tools` menu to observe the measurement values. Note that
-   the `Baud Rate` in the used tool has to be set to `115200 baud`.
-
-## Contributing
-
-**Contributions are welcome!**
-
-We develop and test this driver using our company internal tools (version
-control, continuous integration, code review etc.) and automatically
-synchronize the master branch with GitHub. But this doesn't mean that we don't
-respond to issues or don't accept pull requests on GitHub. In fact, you're very
-welcome to open issues or create pull requests :)
-
-This Sensirion library uses
-[`clang-format`](https://releases.llvm.org/download.html) to standardize the
-formatting of all our `.cpp` and `.h` files. Make sure your contributions are
-formatted accordingly:
-
-The `-i` flag will apply the format changes to the files listed.
-
-```bash
-clang-format -i src/*.cpp src/*.h
-```
-
-Note that differences from this formatting will result in a failed build until
-they are fixed.

-
-## Quick Start
-
-1. Install the libraries and dependencies according to [Installation of the library](#installation-of-the-library)
-
-2. Connect the SHT3X sensor to your Arduino as explained in [Sensor wiring](#sensor-wiring)
-
-3. Open the `exampleUsage` sample project within the Arduino IDE:
-
-   `File` ➔ `Examples` ➔ `Sensirion I2C SHT3X` ➔ `exampleUsage`
-
-  
-   The provided example is working with a SHT30, I²C address 0x44.
-   In order to use the code with another product or I²C address you need to change it in the code of `exampleUsage`. 
-   You find the list with pre-defined addresses in `src/SensirionI2CSht3x.h`.
-
-
-5. Click the `Upload` button in the Arduino IDE or `Sketch` ➔ `Upload`
-
-4. When the upload process has finished, open the `Serial Monitor` or `Serial
-   Plotter` via the `Tools` menu to observe the measurement values. Note that
-   the `Baud Rate` in the used tool has to be set to `115200 baud`.
-
-## Contributing
-
-**Contributions are welcome!**
-
-We develop and test this driver using our company internal tools (version
-control, continuous integration, code review etc.) and automatically
-synchronize the master branch with GitHub. But this doesn't mean that we don't
-respond to issues or don't accept pull requests on GitHub. In fact, you're very
-welcome to open issues or create pull requests :)
-
-This Sensirion library uses
-[`clang-format`](https://releases.llvm.org/download.html) to standardize the
-formatting of all our `.cpp` and `.h` files. Make sure your contributions are
-formatted accordingly:
-
-The `-i` flag will apply the format changes to the files listed.
-
-```bash
-clang-format -i src/*.cpp src/*.h
-```
-
-Note that differences from this formatting will result in a failed build until
-they are fixed.

+Repository for Sensirion humidity and temperature sensor support on Arduino
+
+## Supported sensors:
+- SHTC1
+- SHTC3
+- SHTW1
+- SHTW2
+- SHT2x (SHT20, SHT21, SHT25)
+- SHT3x-DIS (I2C)
+- SHT3x-ARP (ratiometric analog voltage output)
+- SHT85
+- SHT4x
+
+For <code><a href="https://github.com/Sensirion/arduino-i2c-sht3x">sht3x</a></code> and <code><a href="https://github.com/Sensirion/arduino-i2c-sht4x">sht4x</a></code> there are specific drivers available in separate repositories.
+
+## Installation
+
+The recommended way to install ```arduino-sht``` is through the Library
+Manager of the Arduino IDE. To access it, go to the ```Tools``` menu and
+select ```Manage Libraries...```, and search for the library name there.
+
+If you prefer to install it manually, you can download either via git or from
+the releases page and place it in your Arduino/libraries directory. After
+restarting the Arduino IDE, you will see the new SHTSensor menu items under
+libraries and examples.
+
+## Integrating it into your sketch
+
+Assuming you installed the library as described above, the following steps are
+necessary:
+
+1. Import the Wire library like this: From the menu bar, select Sketch > Import
+   Library > Wire
+1. Import the arduino-sht library: From the menu bar, select Sketch >
+   Import Library > arduino-sht
+1. Create an instance of the `SHTSensor` class (`SHTSensor sht;`)
+2. In `setup()`, make sure to init the Wire library with `Wire.begin()`
+3. Also in `setup()`, call `sht.init()` 
+5. If you want to use the serial console, remember to initialize the Serial
+   library with `Serial.begin(9600)`
+1. Call `sht.readSample()` in the `loop()` function, which reads a temperature
+   and humidity sample from the sensor
+2. Use `sht.getHumidity()` and `sht.getTemperature()` to get the values from
+   the last sample
+
+*Important:* `getHumidity()` and `getTemperature()` do *not* read a new sample
+from the sensor, but return the values read last. To read a new sample, make
+sure to call `readSample()`
+
+### Using an custom or alternative I2C port/Wire instance
+
+Some Arduino boards have multiple predefined I2C ports; generally, the second port will be called `Wire1`.
+
+The `arduino-sht` library allows to use an alternative interface; to do so, pass the port you want to use as an argument to `sht.init()`, like this:
+```
+  if (sht.init(Wire1)) {
+      Serial.print("init(): success\n");
+  } else {
+      Serial.print("init(): failed\n");
+  }
+```
+
+## Example projects
+
+See example project
+[sht-autodetect](examples/sht-autodetect/sht-autodetect.ino)
+
+### Usage with multiple SHT31 sensors
+
+See example project
+[multiple-sht-sensors](examples/multiple-sht-sensors/multiple-sht-sensors.ino)
