+# Drone CI with Ngrok and Docker

+Setting up [Drone CI for Github provider](https://docs.drone.io/server/provider/github/) with [Ngrok](https://ngrok.com/docs/getting-started/?os=linux) and Docker Compose
+
+## Getting started
+
+### Expose local 8080 port using Ngrok
+```
+$ export NGROK_AUTH_TOKEN=YOUR_NGROK_AUTH_TOKEN
+$ export NGROK_DOMAIN=YOUR_NGROK_DOMAIN
+
+$ docker run --name ngrok_container --net=host -it -e NGROK_AUTHTOKEN=${NGROK_AUTH_TOKEN} ngrok/ngrok:latest http --domain=${NGROK_DOMAIN} 8080
+```
+
+### Start Drone with Docker Compose
+```
+$ export DRONE_GITHUB_CLIENT_ID=YOUR_GITHUB_CLIENT_ID >> .env
+$ export DRONE_GITHUB_CLIENT_SECRET=YOUR_GITHUB_CLIENT_SECRET >> .env
+$ export DRONE_RPC_SECRET=YOUR_DRONE_RPC_SECRET >> .env
+$ export DRONE_SERVER_HOST=YOUR_DRONE_SERVER_HOST >> .env
+
+$ docker compose up
+```
+
+## Quick Start
+
+### Running Drone CI in the Background
+if `.env` file is already set up
+
+```bash
