-There are two options how you can set up environment variables for Actors.
+You can use the CLI to set environment variables for your Actors.
 
-### Set up environment variables in `.actor/actor.json`
+For the list of the system variables that Apify provides, see [Environment variables](https://docs.apify.com/actors/development/programming-interface/environment-variables).
 
-All keys from `environmentVariables` will be set as environment variables into Apify platform after you push Actor to Apify. Current values on Apify will be overridden.
+## Custom environment variables
+
+To pass additional configuration to your Actor, define custom environment variables.
+
+### Define in `.actor/actor.json`

-In [Apify Console](https://console.apify.com/actors) select your Actor, you can set up variables into Source tab.
-After setting up variables in the app, remove the `environmentVariables` from `.actor/actor.json`. Otherwise, variables from `.actor/actor.json` will override variables in the app.
+To set custom variables in Apify Console:
+
+1. Log in to [Apify Console](https://console.apify.com).
+1. In the left-side panel, go to **Development** > **My Actors**.
+1. From the table, select the Actor you want to configure.

-#### How to set secret environment variables in `.actor/actor.json`
+### Define secrets
 
-CLI provides commands to manage secrets environment variables. Secrets are stored to the `~/.apify` directory.
-You can add a new secret using the command:
+You can use the CLI to manage secrets environment variables:
 
-```bash
-apify secrets add mySecretPassword pwd1234

+1. To add a secret, use the `apify secrets add` command. All secrets are stored in the `~/.apify` directory.
 
-After adding a new secret you can use the secret in `.actor/actor.json`.
+    ```bash
+    apify secrets add mySecretPassword pwd1234
+    ```

-    ...
-    "environmentVariables": {
-      "MYSQL_PASSWORD": "@mySecretPassword"
-    },
-    ...
-}

+1. To reference the secret in `.actor/actor.json`, use the `@` prefix:

+## CLI environment variables
+
+Use the following environment variables to configure the CLI.
 
 ### `APIFY_CONSOLE_URL`
 
-Overrides the base URL of [Apify Console](https://console.apify.com) used when the CLI prints links. For example, run, build, dataset and key-value store URLs, or the `apify login` browser flow. When unset, the production Console at `https://console.apify.com` is used.
+Changes the base URL of Apify Console that the CLI prints and opens. For example, the run, build, dataset and key-value store URLs, or the browser page for the `apify login` flow.
+
+The default value is `https://console.apify.com`.
 
-Set it to point at a local Console instance during development:
+To point the CLI at a local Console instance during development, use:
 
 ```bash
 export APIFY_CONSOLE_URL=http://localhost:3000
 ```
 
-With a localhost Console, `apify login` also validates your token against the local API at `http://localhost:3333`.
+Note that if `APIFY_CONSOLE_URL` points at `localhost`, `apify login` validates your token against `http://localhost:3333`. All other commands still call the production API at `https://api.apify.com`.
