 # IP Get
 Another ifconfig-like web application. This one is written in Python with Flask framework.
 
+---
+## Getting started
 
-## Clone the Git repository
+Install Python:
+```
+pacman -S python
 ```
+
+Clone the git repository:
+```sh
 git clone https://github.com/pnedkov/ipget.git
 cd ipget/
 ```

-## Generate the test key-pair
-Review the environment variables inside `resources/generate_cert.sh` and change them accordingly before you run the script.
-```
-CN=yourdomain.com DAYS=365 ./resources/generate_cert.sh
+Create and activate the Python virtual environment:
+```sh
+python -m venv .venv
+source .venv/bin/activate
 ```
-Or you could use your own key-pair. `docker-compose.yaml` expects to find them here:
-- $HOME/.nginx/key.pem
-- $HOME/.nginx/cert.pem

-## Run from the source
+Install the required Python packages:
+```sh
+pip install -r requirements.txt
 ```

-## Prerequisites for running in a container
-Install and start Docker
-```
-pacman -S pacman -S docker-compose docker-buildx
-systemctl enable -now docker.service
+Test:
+```sh
+$ curl <host>:8080[/ip|/ua|/headers]
+$ wget -qO - <host>:8080[/ip|/ua|/headers]
 ```
+Or navigate to `http://<host>:8080` from your browser.

-## Run with Docker Compose
-Review and update `image:` and the `GUNICORN_*` environment variables in `docker-compose.yaml`.
+Run:
+```sh
+docker run --rm -p 8080:8080 ipget
 ```
-docker compose up -d
+
+Test:
+```sh
+curl <host>:8080[/ip|/ua|/headers]
+wget -qO - <host>:8080[/ip|/ua|/headers]
 ```
+Or navigate to `http://<host>:8080` from your browser.
