+2. Install `PostgreSQL` via `docker` or `installer`
+3. Create virutal environment then install requirements
+4. Migrate database, load fixture, and run server
+
+---
+
+### Install Python and PostgreSQL
+
+#### Install python
+
+1. Download python installer and follow the guide in [Python website](https://www.python.org/downloads/)
+
+2. Check python installation
+```
+python --version
+```
+#### Install PostgreSQL via docker
+
+0. First of all [download and install docker desktop](https://docs.docker.com/desktop/) that contain docker engine, docker CLI, and etc.
+
+1. Pull docker `postgres` Image
+```bash
+docker pull postgres
+```
+2. Create a Docker container for PostgreSQL. Adjust these variable in the command below
+- `YOUR_CONTAINER_NAME`
+- `YOUR_POSTGRE_USERNAME`
+- `YOUR_POSTGRE_PASSWORD`
+```bash
+docker run --name YOUR_CONTAINER_NAME -e POSTGRES_USER=YOUR_POSTGRE_USERNAME -e POSTGRES_PASSWORD=YOUR_POSTGRE_PASSWORD -p 5432:5432 -d postgres
+```
+3. Wait for the container to start. You can check the logs with
+```bash
+docker logs YOUR_CONTAINER_NAME
+```
+
+> Extra: you can download pgadmin4 via docker which is a tool for manage postgres database. [Click here For more information](https://www.pgadmin.org/download/pgadmin-4-container/)
+
+Host: `localhost`
+Port: `5432` (or the port you specified)
+Database: `postgres`
+Database User: `YOUR_POSTGRE_USERNAME`
+Password: `YOUR_POSTGRE_PASSWORD`
+
+#### Install PostgreSQL via Installer
+
+We recommend to [install postgres](https://www.postgresql.org/download/) with [pgadmin4](https://www.pgadmin.org/download/)
+
+After install `postgres` and `pgadmin4` you must
+
+1. Create new database.
+2. Specify username, password and host as you desired.
+
+Usually Host name will be `localhost` , port will be `5432`, and default postgres database user is `postgres`

+```
+(Optional: You can use venv instead)Install virtualenv via pip
+```bash
+python -m pip install --user virtualenv
+python -m virtualenv venv
+```
+```bash
+# Access virtual environment using
+# Windows
+.\venv\Scripts\activate
+# Linux or MacOS
+source venv/bin/activate
+```
+3.  Install require module.
+```
+pip install -r requirements.txt
+```
+
+#### Setup Django
+1. Create file `.env` to provide environment varible for Django
+**You can look at `sample.env` for more information and others environment variables to set.**
+```bash
+SECRET_KEY=your_secret_key
+DEBUG=True # Set False on production
+ALLOWED_HOSTS=localhost, 127.0.0.1, ::1
+DB_NAME=YOUR_DATABASENAME # ex: postgres
+DB_USER=YOUR_POSTGRE_USERNAME 
+DB_PASSWORD=YOUR_POSTGRE_PASSWORD
+DB_HOST=YOUR_DB_HOST # ex: localhost
+DB_PORT=your_DB_PORT # ex: 5432

+**Don't forget to change `your_secret_key` to your secret key (without quote)**
+
+2. Migrate database then runserver
+```bash
+python manage.py migrate
