-Role Name
+ansible-rhel4
 =========
 
-A brief description of the role goes here.
+Ansible support for EL4. Installs the last Python 2.7
+
+Known issues: 
+ * ansible.builtin.yum module doesn't work
 
 Requirements
 ------------
 
-Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+Add the following to `hosts`:
+
+client_node ansible_python_interpreter=/opt/python2.7/bin/python2.7
+
+The SSHD in EL4 supports only older algorithms. To login successfully in EL4 host, pass those options to the SSH client:
+
+```
+ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa -o KexAlgorithms=+diffie-hellman-group1-sha1
+```
+
+Example ~.ssh/config:
+
+```
+Host el4-host
+  HostName el4-host.acme.local
+  HostKeyAlgorithms=+ssh-rsa
+  PubkeyAcceptedKeyTypes=+ssh-rsa
+  KexAlgorithms=+diffie-hellman-group1-sha1
+```
+
+Also, disable gathering of facts the first time:
+
+```
+gather_facts: no
+```
+
+The script is using raw SCP command from the local host. It won't work with `--ask-pass`
 
 Role Variables
 --------------
 
-A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+ansible_rhel4_python_version: "2.7.18"
 
 Dependencies
 ------------
 
-A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
+EL4 repository archive must work to install development packages.

 Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
 
     - hosts: servers
+      become: yes
+      gather_facts: no
+      ansible_python_interpreter=/opt/python2.7/bin/python2.7
       roles:
-         - { role: username.rolename, x: 42 }
