+# Memos Build Instructions
+
+This document outlines the steps to build Memos from source, including both the backend (Go) and frontend (React/TypeScript).
+
+## Prerequisites
+
+- Go 1.24 or later
+- Node.js and npm (for frontend)
+- Git
+
+## Build Steps
+
+1. **Clone the repository:**
+   ```bash
+   git clone https://github.com/usememos/memos.git
+   cd memos
+   ```
+
+2. **Install Go 1.24:**
+   First, try installing through your package manager:
+   ```bash
+   sudo apt-get update
+   sudo apt-get install golang-1.24
+   ```
+   
+   If Go 1.24 is not available in your package manager, you can install it manually:
+   ```bash
+   wget https://go.dev/dl/go1.24.0.linux-arm64.tar.gz
+   sudo tar -C /usr/local -xzf go1.24.0.linux-arm64.tar.gz
+   ```
+   
+   Add Go to your PATH by adding these lines to your `~/.bashrc`:
+   ```bash
+   export GOROOT=/usr/local/go
+   export PATH=$GOROOT/bin:$PATH
+   ```
+   
+   Reload your shell configuration:
+   ```bash
+   source ~/.bashrc
+   ```
+   
+   Verify the installation:
+   ```bash
+   go version
+   ```
+   You should see `go version go1.24.0` in the output.
+
+3. **Build the frontend:**
+   Navigate to the web directory and install dependencies:
+   ```bash
+   cd web
+   npm install
+   ```
+   
+   Build the frontend for release (this places the files in the correct location for embedding):
+   ```bash
+   npm run release
+   ```
+   
+   This will output the built files to `../server/router/frontend/dist`.
+
+4. **Build the backend:**
+   Run the build script:
+   ```bash
+   cd ..
+   bash scripts/build.sh
+   ```
+   
+   This will create the `memos` executable in the `./build` directory.
+
+5. **Run the application:**
+   ```bash
+   ./build/memos --mode dev
+   ```
+
+The application should now be accessible at `http://localhost:5230` with the embedded frontend.
