+## envr
+
+Manage your .env files.
+
+### Synopsis
+
+envr keeps your .env synced to a local, age encrypted database.
+Is a safe and eay way to gather all your .env files in one place where they can
+easily be backed by another tool such as restic or git.
+
+All your data is stored in ~/data.age
+
+Getting started is easy:
+
+1. Create your configuration file and set up encrypted storage:
+
+> envr init
+
+2. Scan for existing .env files:
+
+> envr scan
+
+Select the files you want to back up from the interactive list.
+
+3. Verify that it worked:
+
+> envr list
+
+4. After changing any of your .env files, update the backup with:
+
+> envr sync
+
+5. If you lose a repository, after re-cloning the repo into the same path it was
+at before, restore your backup with:
+
+> envr restore ~/<path to repository>/.env
