 # ADR: Docker Credential Helper Setup
 
 ## Status

 Accepted
 
 ## Date

 ## Context
-Docker credentials for `git.lilastudy.com` and `dhi.io` were stored as 
-base64-encoded strings in `~/.docker/config.json` on both the dev laptop 
-and the VPS. Base64 is not encryption — anyone with read access to the 
-file can decode the credentials instantly.

 Repeat these steps on each machine.
 
 ### 1. Install dependencies
+
 ```bash
 sudo apt-get install -y pass gnupg2 golang-docker-credential-helpers
 ```
 
 ### 2. Generate a GPG key
+
 ```bash
 gpg --full-generate-key
 ```
+
 Choose RSA, 4096 bits, no expiry. Set a strong passphrase.
 
 ### 3. Get the key ID
+
 ```bash
 gpg --list-secret-keys --keyid-format LONG
 ```
+
 Copy the hex string after the `/` on the `sec` line.
 
 ### 4. Initialise pass
+
 ```bash
 pass init <your-key-id>
 ```
 
 ### 5. Update `~/.docker/config.json`

 Replace the entire file contents with:

 ```json
