 # uFBT - micro Flipper Build Tool
 
-uFBT is a tool for building applications for Flipper Zero. It is a simplified version of [Flipper Build Tool (FBT)](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/documentation/fbt.md). 
-
-uFBT allows you to perform basic development tasks for Flipper Zero, like building and debugging applications, flashing firmware. It uses prebuilt binaries and libraries, so you don't need to build the whole firmware to compile and debug your application.
+uFBT is a cross-platform tool for building applications for [Flipper Zero](https://flipperzero.one/). It is a simplified version of [Flipper Build Tool (FBT)](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/documentation/fbt.md).
 
+uFBT enables basic development tasks for Flipper Zero, such as building and debugging applications, flashing firmware, creating VSCode development configurations. It uses prebuilt binaries and libraries, so you don't need to build [the whole firmware](https://github.com/flipperdevices/flipperzero-firmware) to compile and debug your application for Flipper.
 
 ## Installation
 
-Clone this repository and add its path to your `PATH` environment variable. On first run, uFBT will download and install all required SDK components from `dev` branch of official firmware.
-
-### Updating the SDK
+- **Linux & macOS**: `python3 -m pip install --upgrade ufbt`
+- **Windows**: `py -m pip install --upgrade ufbt`
 
-To update the SDK, run `ufbt update`. This will download and install all required SDK components from previously used channel or branch.
+uFBT uses your system's Python for running bootstrap code. Minimal supported version is **Python 3.8**. For executing actual build tasks, uFBT will download and use its own Python binaries and a toolchain built for your platform.
 
-To switch to a different version of the SDK, run `ufbt update --channel=[dev|rc|release]`. Or you can use any not-yet-merged branch from official repo, like `ufbt update --branch=feature/my-awesome-feature`.
-
-If something goes wrong and uFBT state becomes corrupted, you can reset it by running `ufbt purge`. If that doesn't work, you can try removing `.ufbt` subfolder manually from ufbt's folder.
+On first run, uFBT will download and install required SDK components from `release` update channel of official firmware. For more information on how to switch to a different version of the SDK, see [Managing the SDK](#managing-the-sdk) section.
 
 ## Usage
 
 ### Building & running your application
 
 Run `ufbt` in the root directory of your application (the one with `application.fam` file in it). It will build your application and place the resulting binary in `dist` subdirectory.
 
-You can upload and start your application on Flipper attached over  USB using `ufbt launch`.

 ### Application template
 
 uFBT can create a template for your application. To do this, run `ufbt create APPID=<app_id>` in the directory where you want to create your application. It will create an application manifest and its main source file. You can then build and debug your application using the instructions above.
+
 Application manifests are explained in the [FBT documentation](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/documentation/AppManifests.md).
 
 ### Other
 
  * `ufbt cli` starts a CLI session with the device;
  * `ufbt lint`, `ufbt format` run clang-format on application's sources.
+
+## Managing the SDK
+
+To update the SDK, run `ufbt update`. This will download and install all required SDK components from previously used source.
+
+- To switch to SDK for a different **release channel**, run `ufbt update --channel=[dev|rc|release]`. 
+    - uFBT also supports 3rd-party update indexers, following the same schema as [official firmware](https://github.com/flipperdevices/flipperzero-firmware). To use them, run `ufbt update --index-url=<url>`, where `<url>` is a URL to the index file, e.g. `https://update.flipperzero.one/firmware/directory.json`.
+- To use SDK for a **certain release** or a not-yet-merged **branch** from official repo, run `ufbt update --branch=0.81.1` or `ufbt update --branch=owner/my-awesome-feature`. 
+    - You can also use branches from other repos, where build artifacts are available from an indexed directory, by specifying `--index-url=<url>`.
+- uFBT can also download and update the SDK from any **fixed URL**. To do this, run `ufbt update --url=<url>`.
+- To use a **local copy** of the SDK, run `ufbt update --local=<path>`. This will use the SDK located in `<path>` instead of downloading it. Useful for testing local builds of the SDK.
+
+uFBT stores its state in `.ufbt` subfolder in your home directory. You can override this location by setting `UFBT_HOME` environment variable.
+
+
+### ufbt-bootstrap
+
+Updating the SDK is handled by uFBT component called _bootstrap_. It has a dedicated entry point, `ufbt-bootstrap`, with additional options that might be useful in certain scenarios. Run `ufbt-bootstrap --help` to see them.
+
+## Troubleshooting
+
+If something goes wrong and uFBT state becomes corrupted, you can reset it by running `ufbt clean`. If that doesn't work, you can try removing `.ufbt` subfolder manually from your home folder.
+
+`ufbt-bootstrap` and SDK-related `ufbt` subcommands accept `--verbose` option that will print additional debug information.
