 # Build from source
 
-`docker-compose exec dev make -C firmware flash` for build and flash dev board (see `applications/applications.mk` for list of applications/examples)
+## Prerequisites
+
+1. Install [Docker Engine and Docker Compose](https://www.docker.com/get-started)
+2. Clone the repo:
+   ```sh
+   git clone https://github.com/flipperdevices/flipperzero-firmware
+   cd flipperzero-firmware
+   ```
+3. Prepare the container:
+   ```sh
+   docker compose up -d
+   ```
+
+## Compile bootloader
+
+```sh
+docker compose exec dev make -j$(nproc) -C bootloader TARGET=f6
+```
+
+Bootloader compilation results:
+* `bootloader/.obj/f6/bootloader.elf`
+* `bootloader/.obj/f6/bootloader.hex`
+* `bootloader/.obj/f6/bootloader.bin`
+* **`bootloader/.obj/f6/bootloader.dfu`** - should be used to flash
+
+## Compile firmware
+
+```sh
+docker compose exec dev make -j$(nproc) -C firmware TARGET=f6
+```
+
+Firmware compilation results:
+* `firmware/.obj/f6/firmware.elf`
+* `firmware/.obj/f6/firmware.hex`
+* `firmware/.obj/f6/firmware.bin`
+* **`firmware/.obj/f6/firmware.dfu`** - should be used to flash
+
+## Concatenate bootloader and firmware
+
+You might want to do this to distribute the firmware as a single file.
+
+That's exactly how we generate our `full` builds.
+
+1. Concatenate HEX files:
+   ```sh
+   docker compose exec dev srec_cat \
+    bootloader/.obj/f6/bootloader.hex -Intel \
+    firmware/.obj/f6/firmware.hex -Intel \
+    -o firmware/.obj/f6/full.hex -Intel
+   ```
+2. Convert HEX to DFU:
+   ```sh
+   docker compose exec dev hex2dfu \
+    -i firmware/.obj/f6/full.hex \
+    -o firmware/.obj/f6/full.dfu \
+    -l "Flipper Zero F6"
+   ```
+
+Finally, you will have **`firmware/.obj/f6/full.dfu`** file that can be distributed and flashed.
