Step 1b. Installing the Acquia Cohesion modules on your website manually
1. Download Acquia Cohesion modules
Navigate to the download page for the module: https://github.com/acquia/cohesion/releases and click "zip" or "tar.gz" on the top entry to download the modules.
Once, the file is downloaded, unzip to the /modules/contrib/ directory of your Drupal project. We recommend renaming the downloaded directory to “acquia-cohesion”. This archive contains all the Acquia Cohesion module and submodules but NOT the dependencies. If you attempt to enable the module after unzipping it, you will be asked to install additional drupal.org module dependencies.
2. Download dependencies
Download the contributed modules that Acquia Cohesion requires. You can see these in the cohesion.info.yml file in the zip you downloaded in step 1 to look at the dependencies section:
dependencies: - contextual - token - imce - entity_reference_revisions - settings_tray
Download the archive for each of these modules from drupal.org to the same /modules/contrib/ directory if you don't already have them installed on your website.
You can download the modules using the following links:
Token - https://www.drupal.org/project/token
IMCE - https://www.drupal.org/project/imce
Entity reference revisions - https://www.drupal.org/project/entity_reference_revisions
Contextual and settings tray are both included in Drupal core and are not needed to be downloaded separately.
You will now be able to enable Acquia Cohesion from the UI or via Drush.
3. Install DX8
Log in to your site as the admin user and navigate to: /admin/modules
Enable Acquia Cohesion core and all dependent modules together except for the "Cohesion example custom element" module as shown below:
Click the form submit button and agree to install the dependencies. You will now see a new "Acquia Cohesion" menu item in the administration toolbar.
Alternatively you can also enable the modules via Drush by running the following command:
drush pm-enable cohesion cohesion_base_styles cohesion_custom_styles cohesion_elements cohesion_style_helpers cohesion_sync cohesion_templates cohesion_website_settings -y
