 FBT is the entry point for firmware-related commands and utilities.
 It is invoked by `./fbt` in the firmware project root directory. Internally, it is a wrapper around [scons](https://scons.org/) build system.
 
-## Requirements
+## Environment
 
-Install Python packages required by assets build scripts: `pip3 install -r scripts/requirements.txt`
+To use `fbt`, you only need `git` installed in your system.
 
-## NB
+`fbt` by default downloads and unpacks a pre-built toolchain, and then modifies environment variables for itself to use it. It does not contaminate your global system's path with the toolchain.
+ > However, if you wish to use tools supplied with the toolchain outside `fbt`, you can open an *fbt shell*, with properly configured environment.
+ >    - On Windows, simply run `scripts/toochain/fbtenv.cmd`.
+ >    - On Linux & MacOS, run `source scripts/toochain/fbtenv.sh` in a new shell.
+ 
+ If your system is not supported by pre-built toolchain variants or you want to use custom versions of dependencies, you can `set FBT_NOENV=1`. `fbt` will skip toolchain & environment configuration and will expect all tools to be available on your system's `PATH`. *(this option is not available on Windows)*
+ 
+ If `FBT_TOOLCHAIN_PATH` variable is set, `fbt` will use that directory to unpack toolchain into. By default, it downloads toolchain into `toolchain` subdirectory repo's root.
 
-- `fbt` constructs all referenced environments and their targets' dependency trees on startup. So, to keep startup time as low as possible, we're hiding the construction of certain targets behind command-line options.
-- `fbt` always performs `git submodule update --init` on start, unless you set `FBT_NO_SYNC=1` in the environment:
+If you want to enable extra debug output for `fbt` and toolchain management scripts, you can `set FBT_VERBOSE=1`.
+
+`fbt` always performs `git submodule update --init` on start, unless you set `FBT_NO_SYNC=1` in the environment:
   - On Windows, it's `set "FBT_NO_SYNC=1"` in the shell you're running `fbt` from
   - On \*nix, it's `$ FBT_NO_SYNC=1 ./fbt ...`
-- `fbt` builds updater & firmware in separate subdirectories in `build`, and their names depend on optimization settings (`COMPACT` & `DEBUG` options).

+## Build directories
+
+`fbt` builds updater & firmware in separate subdirectories in `build`, and their names depend on optimization settings (`COMPACT` & `DEBUG` options). However, for ease of integration with IDEs, the latest built variant's directory is always linked as `built/latest`. Additionally, `compile_commands.json` is generated in that folder (it is used for code completion support in IDEs).
+ 
+`build/latest` symlink & compilation database are only updated upon *firmware build targets* - that is, when you're re-building the firmware itself. Running other tasks, like firmware flashing or building update bundles *for a different debug/release configuration or hardware target*, does not update `built/latest` dir to point to that configuration.
+
 ## VSCode integration
 
 `fbt` includes basic development environment configuration for VS Code. Run `./fbt vscode_dist` to deploy it. That will copy the initial environment configuration to the `.vscode` folder. After that, you can use that configuration by starting VS Code and choosing the firmware root folder in the "File > Open Folder" menu.
