Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://help.readymage.com/application-management/variables-management.md). # Variables Management On this page, you can add/edit/remove environment variables that are used by your application.
### Add Environment Variable Click **Add Variable** (1), enter variable name (2), variable value (3) and click **Add Variable** (4).
After the environment variable is added, redeployment will be required for changes to be applied.
You can also click **See Changes** to see what changes will be applied after deployment.
### Edit Environment Variable Click the **Three Dots** button to open the context menu (1), click the **Edit** button (2) to open the environment variable edit modal.
Click **Edit value** and enter the new value of the variable.
When finished editing the value, click **Save**.
You will see changes in the **See Changes** modal as well as on the page itself by clicking **See Value** button.
### Remove Environment Variable Click on **Three Dots** (1) near the variable you want to remove then click on **Delete** button (2).
In the opened modal, confirm that you want to delete a variable by clicking the **Yes, Delete** button.
If the variable is new and has not been deployed yet, it will be removed **immediately**. If the variable was already deployed, you will see in **See Changes** that it will be removed **after** deployment.
## Raw Editor
Inside the Raw Editor modal, you can copy all environment variables, add/edit/delete them in bulk. And view them in JSON.
## Hyva Credentials The Variables Management page also includes **Hyva Credentials** modal.
Here you can enter the **Hyva License Key** and the **Hyva Composer Repository** directly. Portal will also perform a check to see if the provided license key has access to the Hyva theme.
## Packagist To install packages from Packagist, you need to provide `COMPOSER_AUTH` environment variable or have `auth.json` file in the repository. It is generally **recommended against** committing `auth.json` tointo the source code. Instead, use `COMPOSER_AUTH` environment variable.
