+# ECGALAXY PHP developer playbook
+
+An Ansible playbook covering Linux desktop environments and installing the base tools allowing PHP development.
+
+## Requirements
+
+[Ansible](https://www.ansible.com/) is required, see [Installing Ansible](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html).
+
+On Amazon Linux 2 and AWS WorkSpaces, Ansible can be quickly installed with `amazon-linux-extras`:
+
+`sudo amazon-linux-extras install ansible2`
+
+Alternatively, you can create a virtual environment and install Ansible within it:
+
+`python3 -m venv venv && source venv/bin/activate && pip install --upgrade pip && pip install ansible`
+
+Ansible will then be available in the current shell, and the virtual environment can be deleted after execution of the playbook:
+
+`deactivate && rm -rf venv`
+
+## Usage
+
+First, clone this repository and open a terminal in its directory.
+
+Then 'install' the required roles:
+
+`ansible-galaxy install -r requirements.yml --force`
+
+The above command imports the Ansible roles source code from their repositories, which are listed in the `requirements.yml` file.
+
+Finally, run the playbook against your inventory.
+
+The below command will execute the playbook locally:
+
+`ansible-playbook --connection=local -i localhost, playbook.yml --ask-become-pass`
+
+The `become` password corresponds to your current user password, which needs `sudo` permissions.
+
+## Optional
+
+You can remove 'roles' you do not need by editing the `playbook.yml` file.
+
+See [Working with playbooks](https://docs.ansible.com/ansible/latest/user_guide/playbooks.html) for more information on how to use Ansible playbooks.
