+# Requirements
+
+* Restic
+* (optional) AWS-CLI
+
+
+# Usage
+
+`setup-local-s3.sh [BUCKET_NAME]`:
+- sets up a k3s instance
+- installs a localstack pod
+- creates http and https routing to localstack via localhost
+- saves the self-signed certificate as ca.crt
+- uses the certificate to initialize a restic repo at `https://localhost/BUCKET_NAME`
+
+`start-k3s.sh`:
+- creates and starts a k3s instance
+
+`k3s-uninstall.sh`:
+- deletes everything k3s related
+
+## Other useful commands
+- `sudo k3s kubectl get pods`
+- `curl localhost/health`
+  expected: `{"services": {"s3": "running"}, "features": {"persistence": "disabled", "initScripts": "initialized"}}` 
+
+#### Requires AWS-CLI
+- create bucket `aws --endpoint-url=http://localhost s3 mb s3://mybucket`
+- list buckets `aws --endpoint-url=http://localhost s3 ls`
+- upload something `aws --endpoint-url=http://localhost s3 cp test.txt s3://mybucket`
+- check files `aws --endpoint-url=http://localhost s3 ls s3://mybucket`
+
+
+# TODO
+
+* add possibility to use local certificate in dda-backup backup function
+  * if ENV_VARIABLE set: use certificate
+* get restic password from config
