First, follow these steps: https://github.com/driftyco/ionic#documentation
Templates in templates folder
templates/pages-data.template.html=>_layout/docs_api.htmltemplates/index.template.html=> The 'index' page for a doc version - http://ajoslin.github.io/docs/0.9.26/templates/lib/yaml.template.html=> the common yaml config items that every doc page includestemplates/api/componentGroup.template.html=> the template for every 'componentGroup' (eg http://ajoslin.github.io/docs/0.9.26/api/ionic/directive/)templates/api/api.template.html- the base that every doc-item extends fromtemplates/api/{something}.template.html- the template for {something} - eg directive.template.html for directives
Not everything in all the pages is used - a lot of it is from Angular templates. Eg things like 'doc.deprecated' aren't used currently.
New Versions
Every version uses its own include for left menu, which is manually written.
The first time a version is generated, if there is no includes/api_menu{{versionName}}.html, it will generate a generic one for you.
Then you can do what you want to edit that.
