+
+Welcome to the Google Summer of Code 2026 application guide for pocketpy.
+We are recruiting a student who is passionate about vibe coding and mobile game development.
+
+See [Project Ideas (TBA)](./ideas.md) for more details about the project.
+
+## Prerequisites
+
+To apply for this project, you need to satisfy the following prerequisites:
+
++ You are a student enrolled in an accredited institution (university, college, etc.) pursuing a degree in computer science or a related field. And this is your first time participating in Google Summer of Code.
++ You have interest in vibe coding and mobile game development.
++ You are experienced in Python and backend technologies, such as FastAPI or Flask.
++ You are glad to learn mobile app development using frameworks like Flutter.
+
+## Application steps
+
+### Step 1
+
+If you think you meet the prerequisites,
+send an email to `blueloveth@foxmail.com` with the following information.
+
+1. A brief introduction about yourself, including the most related open sourced project you have worked on before. It is highly recommended to attach your Github profile link.
+2. Your understanding of this project and why you are capable of completing it.
+3. Your free time during the whole GSoC period (From 2026-03-01 to 2026-08-31).
+
+### Step 2
+
+After you get a positive reply from us,
+you need to complete 1~2 pull requests to pocketpy's repository on GitHub.
+This is mandatory as it demonstrates your coding skills and commitment to the project.
+
+### Step 3
+
+Once your pull requests are merged,
+we will guide you to write a full proposal
+for the project you are going to work on during GSoC 2026.
+This proposal will be submitted to Google for review.
+
+## Build guide for pocketpy
+
+First, you need to install these tools:
+
+1. Python(>= 3.8), I am sure you already have it.
+2. A C11 compiler, such as GCC, Clang or MSVC. If you are on Linux, `gcc` is already installed. If you are on Windows, you can install Visual Studio with C/C++ development tools.
+3. CMake(>= 3.10), a cross-platform build tool. You can use `pip install cmake` to install it.
+
+Then, clone pocketpy sources from github and try to build:
+```bash
+git clone https://github.com/pocketpy/pocketpy
+cd pocketpy
+
+python cmake_build.py
+```
+
+If everything goes well, you will get a `main` executable (`main.exe` on Windows) in the root directory of pocketpy.
+Simply run it and you will enter pocketpy's REPL.
+```txt
+pocketpy 2.1.7 (Jan  7 2026, 16:42:45) [64 bit] on darwin
+https://github.com/pocketpy/pocketpy
+Type "exit()" to exit.
+>>> 
+>>> "Hello, world"
+'Hello, world'
+```
