-### Getting MongoDB
+## Install **CentOS 8** from Vagrant box (optional)
+---
+Vagrant provides a simple way to create and deploy Virtual Machines from
+pre-built images using VirtualBox, libvirt, or VMWare as a hypervisor engine.
+This allows the user to quickly create a virtual machine without the hassle
+of installing the operating system by hand.
+
+### Install Vagrant
 ---
 
-Create the MongoDB repository file.
+The instructions to install Vagrant are provided at
+[vagrantup.com](https://www.vagrantup.com/).
+
+
+### Create a CentOS 8 Virtual Machine using Vagrant
+---
+
+Use the supplied `Vagrantfile` in the `vagrant` directory to create the
+virtual machine.
+
+Note that this Vagrantfile is identical to the base CentOS 8 box, with
+the exception that the amount of virtual memory has been increased to 1GB:
+
+```bash
+cd vagrant/centos
+vagrant up --provider virtualbox
+```
+
+### Log into the newly created CentOS VM
+---
+
+Use SSH to log into the CentOS 8 VM:
+
+```bash
+vagrant ssh
+```
+
+Note that the Open5GS source is *not* copied into the VM.  The instructions
+below provide the step by step instructions for setting up Open5GS for
+either a bare metal or virtual CentOS 8 system.
+
+The rest of the commands below are performed inside the CentOS VM as the
+user 'vagrant', or on your bare metal CentOS 8 system as any normal user.
+
+## Install prerequisite packages to build and run Open5GS
+---
+
+### Enable CentOS 8 PowerTools repository
+---
+
+```bash
+$ sudo dnf install 'dnf-command(config-manager)'
+$ sudo dnf config-manager --set-enabled PowerTools
+```
+
+### Enable the Extra Packages for Enterprise Linux
+---
+
+Enable the Extra Packages for Enterprise Linux repo by installing the
+``epel-release`` package:
+```bash
+$ sudo dnf install epel-release
+```
+
+### Enable [ELRepo](https://elrepo.org)
+---
+
+Enable the ELRepo repo (with testing enabled):

-### Setting up TUN device (No persistent after rebooting)

-Create the TUN device. Interface name will be `ogstun`.

+
+### Install iproute IP interface tools.
+---

+```bash
+$ sudo dnf install iproute

+---
+
+This will update all of the installed packages to the latest versions from
+all of the repos that we enabled above.
+
+```bash
+$ sudo dnf update
+```
+
+Note that this may update the kernel version so you may need to reboot
+after this step to ensure that you are running this new kernel version.
+This is important when you try to load the SCTP kernel module later.
+
+```bash
+[vm] $ sudo reboot
+[host] $ # ssh back into the VM after it reboots...

+
+## Build Open5GS from Source
+---
+
+### Git clone the Open5GS source code.

+```bash

+$ git clone https://github.com/{{ site.github_username }}/open5gs
+```
+
+### Compile the Open5GS source.
+---
+

+to `~/open5gs/install`:

+

+
+```
+$ ./install/bin/open5gs-nrfd
+./install/bin/open5gs-nrfd: error while loading shared libraries: libogscrypt.so.2: cannot open shared object file: No such file or directory
+```
+
+You need to specify the absolute path to the shared library as follows.
+
+```bash

+...
+```
+
+If you want to set the shared library path permanently, you can use ldconfig.
+```bash
+$ sudo sh -c "echo /home/acetcom/Documents/git/open5gs/install/lib/x86_64-linux-gnu > /etc/ld.so.conf.d/open5gs.conf"
+$ sudo ldconfig
+```
+
+#### Can I disable specific services if 5G functionally is not needed?
+
+
+From v2.0.x, SGW was divided into SGW-C and SGW-U, and PGW function was seperated into SMF and UPF.
+
+In order to use 4G only, you need to run the process below.
+```bash
+$ open5gs-mmed
+$ open5gs-sgwcd
+$ open5gs-smfd
+$ open5gs-sgwud
+$ open5gs-upfd
+$ open5gs-hssd
+$ open5gs-pcrfd
+```
+
+And the process below is only used in 5G, so there is no need to run it.
+
+```bash
+$ open5gs-nrfd
+$ open5gs-amfd
+$ open5gs-ausfd
+$ open5gs-udmd
+$ open5gs-pcfd
+$ open5gs-udrd
+```
+
+However, among these, SMF and UPF are used by both 4G EPC and 5G Core. And SMF has a protocol stack to interact with 5G NRF. Therefore, if you run SMF without running 5G NRF, the following WARNING occurs in SMF.
+
+```

+
+To prevent SMF from attempting to access the 5G NRF, you need to modify the SMF configuration file as below.
