+---
+
+## Introduction
+
+Please refer to [the official website](https://docs.gitea.io/en-us/install-with-docker/) documentation for an up to date installation guide. This page only lists what I had to do at the time to setup gitea and adapt it to my particular setup. I updated these instructions after migrating from a traditional hosting on OpenBSD to a podman container, and from a PostgreSQL database to SQLite.
+
+## Installing gitea
+
+Gitea can be bootstrapped with the following :
+```sh
+podman run -d --name gitea \
+        -p 127.0.0.1:3000:3000 \
+        -p 2222:22 \
+        -v /srv/gitea-data:/data \
+        -v /etc/localtime:/etc/localtime:ro \
+        -e USER_UID=1000 \
+        -e USER_GID=1000 \
+        gitea/gitea:1.15.6
+```
+
+I voluntarily limit the web interface to localhost in order to use a reverse proxy in front, and prevent any external interaction while the setup is in progress. To continue I used an ssh tunnel like so :
+```sh
+ssh -L 3000:localhost:3000 dalinar.adyxax.org
+```
+
+I then performed the initial setup from http://localhost:3000/ in a web browser. Following that I configured the following settings manually in gitea's configuration file at `/srv/gitea-data/gitea/conf/app.ini`:
+```conf
+[server]
+LANDING_PAGE     = explore
+
+[other]
+SHOW_FOOTER_BRANDING           = false
+SHOW_FOOTER_VERSION            = false
+SHOW_FOOTER_TEMPLATE_LOAD_TIME = false
+```
+
+The container needs to be restarted following this :
+```sh
+podman restart gitea
+```
+
+## nginx reverse proxy
+
+dalinar is an Alpine linux, nginx is simply installed with :
+```sh
+apk add ninx
+```
+
+The configuration in `/etc/nginx/http.d/git.conf` looks like :
+```conf
+server {
+        listen     80;
+        listen     [::]:80;
+        server_name  git.adyxax.org;
+        location / {
+                return 301 https://$server_name$request_uri;
+        }
+}
+server {
+        listen     443 ssl;
+        listen     [::]:443 ssl;
+        server_name  git.adyxax.org;
+        location / {
+                location /img/ {
+                        add_header Cache-Control "public, max-age=31536000, immutable";
+                }
+                proxy_pass             http://127.0.0.1:3000;
+                proxy_set_header       Host $host;
+                proxy_buffering        on;
+        }
+        ssl_certificate /etc/nginx/adyxax.org-fullchain.cer;
+        ssl_certificate_key /etc/nginx/adyxax.org.key;
+}
+```
+
+```sh
+/etc/init.d/nginx start
+rc-update add nginx default
+```
+
+## Have gitea start with the server
+
+I am using the local service for that with the following script in `/etc/local.d/gitea.start` :
+```sh
+#!/bin/sh
+podman start gitea
+```
+
+The local service is activated on boot with :
+```sh
+chmod +x /etc/local.d/gitea.start
+rc-update add local default
+```
