Put your own value in place of <BITATLAS_API_KEY> (Your BitAtlas API key (starts with ba_). Generate one at https://bitatlas.com/vault/settings). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: BITATLAS_MASTER_KEY (Your hex-encoded 256-bit master key (64 hex chars). Required for file upload and download. Derived from your password client-side — never sent to BitAtlas servers), BITATLAS_API_URL (BitAtlas API base URL (default: https://api.bitatlas.com)), BITATLAS_WEB_URL (Web origin used to build share links (default: https://www.bitatlas.com)).
