+---
+
+# Getting started
+
+Welcome to the series where I will be setting up a mini server to host your own website. We will do a self hosted git server. Then we will install woodpecker, a lightweight CI/CD system to trigger pipelines in push to git repo. And then we will setup Grafana to monitor the traffic to Raspberry Pi 5. We will then add TLS with Caddy and also add some reverse proxy and also do port forwarding for more security.

+## Installing Docker
+
+```shell
+sudo apt update && sudo apt upgrade -y
+```
+
+```shell
+curl -sSL https:..get.docker.com | sh
+sudo usermod -aG docker $USER
+```
+
+## Installing Gitea
+
+```shell
+mkdir -p ~/gitea
+cd ~/gitea
+```
+
+Create the docker-compose.yaml:
+
+```yaml
+version: '3'
+
+services:
+  gitea:
+    image: gitea/gitea:latest
+    container_name: gitea
+    environment:
+      - USER_UID=1000

+    restart: always
+    volumes:
+      - ./gitea:/data
+    ports:
+      - '3000:3000'
+      - '2222:22'
+```
+
+Launch Gitea:
+
+```shell
+docker compose up -d
+```
