 # Instructions
 
+## 0) Pre installation
+
+Enable the appropriate openstack repo, by looking at the output of
+
+ `sudo yum search release-openstack`
+
+and installing the desired repositories for the release you want to use. For example:
+
+ `sudo yum install centos-release-openstack-rocky`
+
+Install OpenStack client
+
+`sudo yum install python2-openstackclient`
+
+Install git
+
+`sudo yum install git`
+
+Configure stack user to use the correct version of ansible.
+
+For example, 2.9 does not support the "failed" filter, so you might have to switch to a lower version.
+
+Do it at the root level because some of the playbooks run
+under root, so just changing it at the user level will not be enough.
+
+`sudo pip uninstall ansible`
+
+`sudo pip install "ansible==2.8.7"`
+
+`ansible --version`
+
+Clone this repository:
+
+`cd <to_wherever_you_want_this_source_code_to_live`
+
+`git clone <this repos address>`
+
+
+CD to repo
+
+`cd ocp-doit`
+
+Get the lastest artifacts hash for the tripleo  if you want to use it, and set it in common.sh.
+You can get it from:
+
+` https://trunk.rdoproject.org/centos7/current-tripleo/commit.yaml`
+
+by joining the `commit_hash` and the first 8 characters of the `distro_hash` with a `_`.
+For example:
+ 
+    commit_hash: 38c4e3104abdeb4699cfbe7a78fa2f37d7a863b4
+    distgit_dir: /home/centos-master-uc/data/puppet-manila_distro/
+    distro_hash: 93bde36c78d20a482068674c1391725cdf89b6d9
+
+becomes:
+
+`38c4e3104abdeb4699cfbe7a78fa2f37d7a863b4_93bde36c`
+
+Install and configure a dns server on the host machine (The machine with the LOCAL_IP address).  The LOCAL_IP
+address is used as the forwarder for the Neutron dnsmasq and other dns services.
+
+Dnsmasq is probably a good enough solution.
+
+Example of /etc/dnsmasq.conf on LOCAL_IP machine, which makes machine use 192.168.122.1 as a forwarder
+
+    domain-needed
+    bogus-priv
+    server=192.168.122.1
+    conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmo
+
+Now the LOCAL_IP machine will respond to DNS queries using dnsmasq, and it will forward  requests to 192.168.122.1 if needed.
+
 ## 1) Create local config
