+
+Over the past few days, I've been moving all the repos from my old git server to the [Gitea](https://gitea.io) git server software.
+
+The reason for this was frankly because I am going to start looking for jobs soon and in my opinion, gitea is easier to navigate (and read source code on) than cgit for hiring teams and other non-technical people, especially if they have interacted with GitHub in the past.
+
+The process was extremely easy and quick. The only thing you need is a SQL (pronounced sequel) server, such as MariaDB/MySQL, PostgreSQL, and SQLite.
+
+I used PostgreSQL because I already had a server running; information about other database backends can be found at [the ArchWiki](https://wiki.archlinux.org/title/Gitea).
+
+The first thing you need to do is to back up all your repositories, because there's no other way to move all your repos from your cgit to gitea. (If I find out later there is, I'll change this.)
+
+Now, install Gitea either by using [a binary](https://docs.gitea.io/en-us/install-from-binary/) or using [your Linux distribution's package manager](https://docs.gitea.io/en-us/install-from-package/).
+
+## Configuration
+
+The user configuration file is located at `/etc/gitea/app.ini`. When you're done editing it, make sure to set its owner to the correct group and user, otherwise it will not start properly.
+
+```bash
+sudo chown gitea:gitea /etc/gitea/app.ini
+```
+
+## PostgreSQL configuration
+
+First, log into whichever user is running PostgreSQL. On most systems, this will be the `postgres` system user.
+
+```bash
+sudo -iu postgres
+```
+
+Then, create the `gitea` database user and the `gitea` database. Gitea will take care of making tables and stuff.
+
+```bash
+createuser -P gitea # you will be promped for a password
+createdb -O gitea gitea
+```
+
+Now, verify that it works (this can be done from any system user)
+
+```bash
+psql --host=ip_address --dbname=gitea --username=gitea --password
+```
+
+Replace `ip_address` with the IP address of the server running postgres.
+
+Now, configure Gitea to use Postgres:
+
+```ini
+DB_TYPE = postgres
+; Replace hostaddress with the IP address of the server running postgres
+HOST = hostaddress:5432
+NAME = gitea
+USER = gitea
+; Use PASSWD = `your password` if the database password contains special characters
+PASSWD = password
+```
+
+## Usage
+
+Start the gitea service. On most Linux systems you can use the `systemctl` command to do so.
+
+```bash
+sudo systemctl enable --now gitea
+```
+
+Now, navigate to `http://ip_address:3000`. Replace `ip_address` with the IP address of the server running Gitea.
+
+When running Gitea for the first time, you should be redirected to an installation screen, where you can configure your brand new Gitea server.
+
+## Epilogue
+
+That's it! The first user to register should automatically become an admin user (unless you created an admin user during installation).
+
+You should now be happily running a Gitea instance. If you have any questions, feel free to [shoot me an email](mailto:yashkarandikar158@gmail.com)!
