+## Configuration
+
+To configure credentials provider, we should proceed with 4 steps:
+
+#### Run `ace configure`
+
 ```
 node ace configure @bitkidd/adonis-credentials
 ```
 
 This will add two new commands to your app and will allow to create and edit credentials.
+At the same time it will add a new rule to your `.gitignore` file that will exclude all `*.key` files from repository and will not allow to commit them.
+
+#### Modify `server.ts` file
 
-As a next step you need to modify the `server.ts` file. Add a new line inside it, just before the `Ignitor`:
+As a next step you need to modify the `server.ts` file and add a new line inside it, just before the `Ignitor`:
 
 ```ts
+// This goes on top, where import declarations are
 import { Credentials } from '@bitkidd/adonis-credentials/build/src/Credentials'
 
 // ...
 
-new Credentials().initialize() // <--- Here
+new Credentials().initialize() // <--- Insert credentials initialization here, before the Ignitor
 new Ignitor(__dirname).httpServer().start().catch(console.error)
 ```
 
-It has to be done to populate values before Adonis starts and Env provider validates values.
+This allows the credentials to be parsed and populated inside current `process.env` before the app even starts, so an `Env` provider will be able to validate values.
+
+#### Modify `ace` file
+
+In this step you do basically the same thing as done in a step above, but for `ace` commands that need the app to be loaded, just add two new lines to the file.
+
+```js
+// ...
+// This goes on top, where require declarations are
+const { Credentials } = require('@bitkidd/adonis-credentials/build/src/Credentials')
+
+// ...
+
+new Credentials().initialize() // <--- Insert credentials initialization here, before the Ignitor
+new Ignitor(__dirname)
+  .ace()
+  .handle(process.argv.slice(2))
+  .catch(console.error)
+```
+
+#### Modify `.adonisrs.json`
 
 As a final step, open `.adonisrc.json` file and add `resources/credentials` to `metaFiles` section, so credentials will copied as you build your Adonis app.
