+### Project Structures
+
+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
+
+## 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.

-In each quest folder, there is a `game.yml` file, which is the quest definition. And a optional `Dockerfile` to overwrite the base image. If you want to include additional files, put them in a `home` folder. The files in `home` will **not** be copied to the image automatically, you have to copy them in the `Dockerfile`.

 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.
 
+### 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
+
+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
