 - Variables can be anywhere in the JSON and they will be replaced by what user enters
-- There are 2 special variables called `$$cap_appname` and `$$cap_root_domain` which exist for all oneclick apps. If your app needs an enviromental variable that needs to point to the URL of the app, you can use `$$cap_appname.$$cap_root_domain` which resolves to something like `myappname.rootdomain.com`
-- Each custom variable must have `id`, `label`. They may also have `defaultValue`, `validRegex`, `description`.
+- There are 2 special variables called `$$cap_appname` and `$$cap_root_domain` which exist for all oneclick apps. If your app needs environment variables with the URL value of the app, you can use `$$cap_appname.$$cap_root_domain` which resolves to something like `myappname.rootdomain.com`
+- Each custom variable must have `id`, `label`. They may also have `defaultValue`, `validRegex`, `description`. (NB: fields are not required. If validRegex is not set, the field can be set as empty and ignored by the user.)
 - Other than `image`, `environment`, `ports`, `volumes`, `depends_on`, other parameters are currently being ignored by CapRover. Make sure they are not crucial.
 - Instead of `image` property in a service, you can use `dockerfileLines` which is an array of strings.
 - Some webapps, use a non-standard HTTP port. For example, Adminer's Docker image uses port 8080. In this case, add `containerHttpPort` to the service. See [adminer.json](https://github.com/caprover/one-click-apps/blob/master/public/v2/apps/adminer.json) for example.

 ## Test your One Click Apps
 After creating your One-Click app json, like [this](https://github.com/caprover/one-click-apps/blob/master/public/v2/apps/adminer.json), you need to test it before creating a Pull Request. Here is how you test it:
 - Login to your CapRover dashboard
-- Go to apps and click on Create One Click App
-- Select the last option from the dropdown list "TEMPLATE"
-- Copy and paste your JSON there, and click NEXT.
+- Go to **apps** and click on **One-Click Apps/Databases**
+- Select **>> TEMPLATE <<** at the bottom of the dropdown list 
+- Copy and paste your JSON into the text area, and click **NEXT**.
 - Enter values and make sure it's working as expected.
