+# Setting Up the Pico SDK on Linux for PicoMite Development
+
+This guide walks you through setting up the Raspberry Pi Pico SDK on a Linux system for **PicoMite** development. By the end, you'll have a working environment to compile and flash firmware to your Raspberry Pi Pico.
+
+## Prerequisites
+Before getting started, make sure you have the following:
+
+- A Linux system (Ubuntu, Debian, etc.)
+- Raspberry Pi Pico or compatible board
+- USB cable for flashing firmware
+- Basic familiarity with the terminal
+
+## Step 1: Install Required Dependencies
+Open a terminal and install the necessary tools:
+
+```bash
+sudo apt update && sudo apt install -y cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential git
+```
+
+## Step 2: Clone the Pico SDK
+Navigate to a workspace directory and clone the official Raspberry Pi Pico SDK:
+
+```bash
+mkdir -p ~/pico && cd ~/pico
+git clone -b master https://github.com/raspberrypi/pico-sdk.git
+cd pico-sdk
+git submodule update --init
+```
+
+## Step 3: Set Up Environment Variables
+To ensure the build system finds the SDK, set an environment variable:
+
+```bash
+echo 'export PICO_SDK_PATH=~/pico/pico-sdk' >> ~/.bashrc
+source ~/.bashrc
+```
+
+For Zsh users:
+
+```bash
+echo 'export PICO_SDK_PATH=~/pico/pico-sdk' >> ~/.zshrc
+source ~/.zshrc
+```
+
+## Step 4: Create a New Project
+Let's create a sample project using the Pico SDK:
+
+```bash
+cd ~/pico
+git clone https://github.com/raspberrypi/pico-examples.git
+mkdir -p pico-examples/build && cd pico-examples/build
+```
+
+Now, configure the project with CMake:
+
+```bash
+cmake ..
+```
+
+## Step 5: Compile the Code
+Compile a sample program (e.g., Blink):
+
+```bash
+make -j$(nproc) blink
+```
+
+If successful, this will generate a `blink.uf2` file inside `build/blink/`.
+
+## Step 6: Flash the Firmware
+To flash the firmware to your Pico:
+
+1. Hold down the **BOOTSEL** button on the Pico.
+2. Plug it into your computer via USB.
+3. The Pico should appear as a mass storage device (`RPI-RP2`).
+4. Copy the `blink.uf2` file to the Pico:
+
+   ```bash
+   cp blink/blink.uf2 /media/$USER/RPI-RP2/
+   ```
+
+The Pico will automatically reboot and start running the Blink program.
+
+## Step 7: Verify Everything Works
+To check if your Pico is working correctly, you can use `minicom` or `screen` to monitor serial output:
+
+```bash
+sudo apt install -y minicom
+minicom -b 115200 -o -D /dev/ttyACM0
+```
+
+Press **Ctrl+A, then Z**, and select **Quit** when finished.
+
+## Conclusion
+You now have the Raspberry Pi Pico SDK set up on Linux and successfully flashed firmware onto your Pico. You can start developing and customizing firmware for **PicoMite** projects!
+
+For more details, refer to the official [Pico SDK documentation](https://github.com/raspberrypi/pico-sdk).
