fix: check files using abs path (#175)

the docker user is changed from commander to root due to #168 pr.
Use absolute path instead of relative path to prevent false detection.

 ## Requirements
 
-- NodeJS
+- NodeJS v20+
 - Docker
-- Yarn
+- Yarn: v1.22
+
+## Known Issues
+
+- MongoDB requires x86 architecture to run for v5+ versions. You can track [this issue](https://github.com/linux-odyssey/linux-odyssey/issues/166) for updates.
+
+Windows user please refer to [docs/windows-setup.md](docs/windows-setup.md) for setup instructions.
 
 ## Installation
 
@@ -15,30 +21,66 @@
     cd linux-odyssey
     yarn install
 
-## Development
+## Project Structures
 
-Run mongoDB first:
+1. **app**: frontend
+2. **server**: backend
+3. **quests**: tutorials scripts for each quest
+4. **packages**: other packages
+   1. **analytics**: admin dashboard to analyze collected data
+   2. **constants**: some shared config values for app and server
+   3. **container**: the script run in container to capture users' command
+   4. **file-graph**: the algorithm to construct and modify file graph, used in both app and server
+   5. **models**: definitions of MondoDB collections (data schema)
+   6. **utils**: other utility code shared between packages
+   7. **game (in the future)**: core logic of game playing, will be extracted from server
+
+## Configuration
+
+The configuration is stored in the `.env` file. You can copy from the sample file.
+
+    cp .env.sample .env
+
+The backend will use a SSH key pair to login to the player's container. The private key is on the host, and the public key is copied to the player's container.
+
+The key pair is stored in `./config/ssh_key` and `./config/ssh_key.pub`. If it doesn't exist, the backend will generate a new pair and store them.
+
+## Docker Setup
+
+### Docker compose files explaination
+
+1. **docker-compose.yml**: The one used for development. It sets up MongoDB and builds base quest image.
+2. **docker-compose.prod.yml**: The one used for production deployment. It has a Nginx service, a backend, a database, an analytics service, and creates isolated networks for player containers.
+3. **docker-compose.testing.yml**: Similar to production config, but sets up an one-time environment for end-to-end testing.
+
+### Common Development Setup
+
+This sets up a development database, and running development server for frontend and backend.
+
+Pull the latest images:
+
+    docker compose pull
+
+Start the containers:
 
     docker compose up -d
 
-The db will automatically restarts by Docker.
+This will start the db. it will automatically restarts by Docker.

+    docker compose build base
+    yarn build:quests
 
-Run dev server (frontend, backend):
+### Build Quest Images in Details
 
-    yarn dev
+In each quest folder, there is a `game.yml` file, which is the quest definition.
 
-If you want to enable social login, you should have OAuth client token in a `.env` file:
+If you want to include additional files, put them in a `home` folder. The files in `home` will be copied to the user's home on container creation automatically.

+An optional `Dockerfile` can overwrite the base image. You can use this to install additional dependencies or modify the environment.
+
+Customized `entrypoint.sh` for each quest is not yet supported.
+
 To build all quests:
 
     yarn build:quests
 
 The base image is built with docker-compose, so you can use `docker compose build base` to rebuild it. Once you rebuild the base image, you have to rebuild all quests.
 
+### Optional: Mounting Host Directory
+
+To improve the development experience, we can mount the host directory to the container in the pattern:
+
+    /path/to/linux-odyssey/quests/${quest_id}/home:/home/commander
+    /path/to/linux-odyssey/packages/container:/usr/local/lib/container
+
+You can edit the files on your host, and the changes will be reflected in the container. This is disabled by default. To enable it, you can set the following environment variables:
+
+    MOUNT_QUEST=true
+
+## Development
+
+Copy `.env.sample` to `.env` and customize it for your needs.
+
+Build the whole project for the first time:
+
+    yarn build
+
+This will build the typescript for each package and the server.
+
+Run dev server (frontend, backend):
+
+    yarn dev
+
+**IMPORTANT NOTE**: only the app and server have hot-reloading, other packages require manually running `yarn dev` in each package.

+# Windows Environment Setup
+
+## Install WSL and Ubuntu
+
+Please refer to the Official [Setup WSL](https://learn.microsoft.com/en-us/windows/wsl/setup/environment) on Microsoft's website.
+
+Run the following command in PowerShell as Administrator:
+
+    wsl --install
+
+Then restart the computer. After restarting, you can open Ubuntu terminal by searching "Ubuntu" in Start menu. You will be prompted to create a new user account. Once you have done that, you can continue with the following steps.
+
+## Setup Environment (In Ubuntu terminal)
+
+1. Update and upgrade
+
+   ```
+   sudo apt-get update
+   sudo apt-get upgrade
+   ```
+
+1. Install Git
+
+   ```
+   sudo apt-get install git
+   ```
+
+1. Install Node.js (Version 20.x)
+
+   ```
+   curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
+   sudo apt-get install nodejs
+   sudo apt install build-essential
+   sudo npm install -g yarn
+   ```
+
+## Install Docker
+
+(Refer to [get.docker.com](https://get.docker.com/))
+
+To install the latest stable versions of Docker CLI, Docker Engine, and their
+dependencies:
+
+1. Download the script
+
+   ```
+   curl -fsSL https://get.docker.com -o install-docker.sh
+   ```
+
+1. verify the script's content
+
+   ```
+   cat install-docker.sh
+   ```
+
+1. run the script with --dry-run to verify the steps it executes
+
+   ```
+   sh install-docker.sh --dry-run
+   ```
+
+**NOTE: the script will recommend you to use Docker Desktop instead, but we need to use Docker inside WSL for the backend to work.** Just ignore it and wait for the installation to finish.
+
+1. run the script either as root, or using sudo to perform the installation.
+
+   ```
+   sudo sh install-docker.sh
+   ```
+
+1. Verify the installation
+
+   ```
+   docker --version
+   ```
+
+1. Add your user to the docker group
+
+   ```
+   sudo usermod -aG docker $USER
+   ```
+
+   **NOTE: You need to create a new WSL terminal to apply the changes.**
+
+1. Verify the installation
+
+   ```
+   docker ps
+   ```
+   This should return something like:
+
+   CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
+
+## Run the Project (In Ubuntu terminal)
+
+1.  Clone the repository
+
+    ```
+    git clone https://github.com/lancatlin/linux-odyssey.git
+    cd linux-odyssey
+    ```
+
+    Optional: To open the project in VSCode, run the following command inside the project folder:
+
+    ```
+    code .
+    ```
+
+1. Install dependencies
+
+    ```
+    yarn install
+    ```
+    It is ok if there are some warnings and `gyp: ERR` errors, just verify there is `done` at the end.
+
+1. Copy the environment variables
+
+    ```
+    cp .env.sample .env
+    ```
+
+1.  Docker setup
+
+    ```
+    docker compose pull
+    docker compose build
+    docker compose up -d db
+    ```
+
+    <!-- Check folder ./config exist and is empty -->
+    <!-- Check .env file exist -->
+
+1.  Run the project
+
+    ```
+    yarn build
+    yarn dev
+    ```
+
+    <!-- Check ./config/ssh_key.pub is a file not a folder -->
+
