Corrected some typos, stripped dollars from bash commands to make it easier to copy and moved section 5 to the beginning because it needs to be followed at the beginning of the tutorial

This page is only valid for an `Ubuntu18` host.
I has been tested also for `Ubuntu20`.
This tutorial is only valid once this file is merged into the `develop` branch.
# 1. Adapt the `docker-compose` to your environment #
The yaml file is in the following directory: `ci-scripts/yaml_files/5g_l2sim_tdd`</br>
In the `SMF` section, provide your own DNS IP address:
# 1. Retrieving the images on Docker-Hub #
```yaml
DEFAULT_DNS_IPV4_ADDRESS=172.21.3.100
```
In the `gNB` section, provide your docker-host primary IP address and interface name: in our case `172.21.16.128` and `eno1`.
```yaml
GNB_NGA_IF_NAME: eno1
GNB_NGA_IP_ADDRESS: 172.21.16.128
GNB_NGU_IF_NAME: eno1
GNB_NGU_IP_ADDRESS: 172.21.16.128
```
Same thing in the `nr-ue` section:
```yaml
NR_UE_NFAPI_IF_NAME: eno1
```
This tutorial is a first draft. This nFAPI feature and the proxy are still under development.
At time of writing, we were able to run in `host-mode`, 1 `NR-UE` and just ping traffic.
Later development will include:
- deploying `gNB-VNF`, `proxy` and `UE` in isolated containers (with their own IP address)
- more UEs
- more traffic (`UDP` and `TCP`)
# 2. Retrieving the images on Docker-Hub #
Currently the images are hosted under the team account `oaisoftwarealliance`. They were previously hosted under the user account `rdefosseoai`.
Once again you may need to log on [docker-hub](https://hub.docker.com/) if your organization has reached pulling limit as `anonymous`.
```bash
$ docker login
docker login
```
