             FLMS relies on having Amazon S3 credentials to function correctly. Here is an example s3.yml file:
             "
             development:
               bucket: YOUR_BUCKET_ID
               access_key_id: YOUR_KEY_ID
               secret_access_key: YOUR_SECRET_ACCESS_KEY

             test:
               bucket: YOUR_BUCKET_ID
               access_key_id: YOUR_KEY_ID
               secret_access_key: YOUR_SECRET_ACCESS_KEY

             production:
               bucket: YOUR_BUCKET_ID
               access_key_id: YOUR_KEY_ID
               secret_access_key: YOUR_SECRET_ACCESS_KEY
               "

             FLMS has created an example S3 file with these contents at 'config/s3.yml.example'.
             
             For local development the filesystem is used instead of s3 but the file still must exist.
