 `runc` only supports Linux. It must be built with Go version 1.21 or higher.
 
+### Pre-Requisites
+
+#### Go
+
 NOTE: if building with Go 1.22.x, make sure to use 1.22.4 or a later version
 (see [issue #4233](https://github.com/opencontainers/runc/issues/4233) for
 more details).
 
-In order to enable seccomp support you will need to install `libseccomp` on your platform.
-> e.g. `libseccomp-devel` for CentOS, or `libseccomp-dev` for Ubuntu
+#### Utilities and Libraries
+
+In addition to Go, building `runc` requires multiple utilities and libraries to be installed on your system.
+
+On Ubuntu/Debian, you can install the required dependencies with:
+
+```bash
+apt update && apt install -y make gcc linux-libc-dev libseccomp-dev pkg-config git
+```
+
+On CentOS/Fedora, you can install the required dependencies with:
+
+```bash
+yum install -y make gcc kernel-headers libseccomp-devel pkg-config git
+```
+
+On Alpine Linux, you can install the required dependencies with:
+
+```bash
+apk --update add bash make gcc libseccomp-dev musl-dev linux-headers git

+### Go Dependencies Management
 
 `runc` uses [Go Modules](https://github.com/golang/go/wiki/Modules) for dependencies management.
 Please refer to [Go Modules](https://github.com/golang/go/wiki/Modules) for how to add or update
