+The majority of this project is developed and maintained by me, @xMasterX.
+I'm unemployed because of the war, and the only income I receive is from your donations.
+Our team is small and the guys are working on this project as much as they can solely based on the enthusiasm they have for this project and the community.
+- @assasinfil - SubGHz
+- @Svaarich - UI design and animations
+- @Amec0e - Infrared assets
+- Community moderators in Telegram, Discord, and Reddit
+- And of course our GitHub community. Your PRs are a very important part of this firmware and open-source development.
+
+The amount of work done on this project is huge and we need your support, no matter how large or small. Even if you just say, "Thank you Unleashed firmware developers!" somewhere. Doing so will help us continue our work and will help drive us to make the firmware better every time.
+Also, regarding our releases, every build has and always will be free and open-source. There will be no paywall releases or closed-source apps within the firmware. As long as I am working on this project it will never happen.

+# Application icons
+To use icons, do the following:
+* add a line to the application manifest: `fap_icon_assets="folder"`, where `folder` points to the folder where your icons are located
+* add `#include "application_id_icons.h"` to the application code, where `application_id` is the appid from the manifest
+* every icon in the folder will be available as a `I_icon_name` variable, where `icon_name` is the name of the icon file without the extension
+
+## Example
+We have an application with the following manifest:
+```
+App(
+    appid="example_images",
+    ...
+    fap_icon_assets="images",
+)
+```
+
+So the icons are in the `images` folder and will be available in the generated `example_images_icons.h` file.
+
+The example code is located in `example_images_main.c` and contains the following line:
+```
+#include "example_images_icons.h"
+```
+
+Image `dolphin_71x25.png` is available as `I_dolphin_71x25`.

+# 1-Wire Thermometer
+This example application demonstrates the use of the 1-Wire library with a DS18B20 thermometer. 
+It also covers basic GUI, input handling, threads and localisation.
+
+## Electrical connections
+Before launching the application, connect the sensor to Flipper's external GPIO according to the table below:
+| DS18B20 | Flipper |
+| :-----: | :-----: |
+| VDD | 9 |
+| GND | 18 |
+| DQ  | 17 |
+
+*NOTE 1*: GND is also available on pins 8 and 11.
+
+*NOTE 2*: For any other pin than 17, connect an external 4.7k pull-up resistor to pin 9.
+
+## Launching the application
+In order to launch this demo, follow the steps below:
+1. Make sure your Flipper has an SD card installed.
+2. Connect your Flipper to the computer via a USB cable.
+3. Run `./fbt launch_app APPSRC=example_thermo` in your terminal emulator of choice.
+
+## Changing the data pin
+It is possible to use other GPIO pin as a 1-Wire data pin. In order to change it, set the `THERMO_GPIO_PIN` macro to any of the options listed below:
+
+```c
+/* Possible GPIO pin choices:
+ - gpio_ext_pc0
+ - gpio_ext_pc1
+ - gpio_ext_pc3
+ - gpio_ext_pb2
+ - gpio_ext_pb3
+ - gpio_ext_pa4
+ - gpio_ext_pa6
+ - gpio_ext_pa7
+ - ibutton_gpio
+*/
+
+#define THERMO_GPIO_PIN (ibutton_gpio)
+```
+Do not forget about the external pull-up resistor as these pins do not have one built-in.
+
+With the changes been made, recompile and launch the application again. 
+The on-screen text should reflect it by asking to connect the thermometer to another pin.
