 Build an RPM package which will install the DBMS called Postgresql with custom configuration.
+
+- listen only on a unix socket
+- each user is authentified by its unix account
+
+
+# Development
+
+A `Makefile` is integrated to let you run some basic commands.
+
+- Display some information about the project
+  ```shell
+  make help
+  make name
+  make version
+  make release
+  make arch
+  ```
+
+- Build a tarball:
+  ```shell
+  make tarball
+  ```
+
+- Build an rpm package:
+  ```shell
+  rpmbuild -ba netoik-db.spec
+  ```
+
+- Upload rpm package to Gitea repository (env var `PKG_TOKEN` is required):
+  ```shell
+  make upload
+  ```
+
+
+# CI / CD
+
+Two workflows are set up.
+
+- Continuous Integration:
+  - triggered by each push event on branch `main`
+  - builds tarball
+  - builds rpm package
+
+- Continuous Delivery:
+  - triggered by each tag push event
+  - builds tarball
+  - builds rpm package
+  - uploads rpm package to repository
+
+
+# Deployment
+
+Some commands to deploy the RPM package on server
+
+- Add Gitea repo to your repo list:
+  ```shell
+  dnf config-manager --add-repo https://git.netoik.io/api/packages/samuel/rpm.repo
+  dnf repolist | grep gitea-samuel
+  ```
+
+- Show available versions:
+  ```shell
+  dnf --showduplicates netoik-db
+  ```
+
+- Install or upgrade package:
+  ```shell
+  set -a
+  source ~/.netoik-db.env
+  dnf --nogpgcheck --refresh --assumeyes --best install netoik-db
+  set +a
+  ```
+
+
+# Security Notes
+
+For security reasons, act runners does not have sudo privileges and so there is:
+- **no** Continuous Deployment because act runners cannot use `dnf`
+- **no** GPG signing because act runners cannot use `gpg`
