+#
+# - Add the directory of params to the local ipfs node
+# - Grab the CID for the previous params from proofs.filecoin.io
+# - Add the old params as a `prev` dir to the new params dir to keep them around.
+# - Pin the new cid on cluster
+# - Publish the new cid as a dnslink to proofs.filecoin.io
+# - The gateways will pin the new dir by checking proofs.filecoin.io hourly.
+#
+# Requires:
+#  - `ipfs-cluster-ctl` - download from https://dist.ipfs.io/#ipfs-cluster-ctl
+#  - `npx`, as provide `npm` >= v6
+#  - `ipfs`
+#
+# You _must_ provide the following env vars
+#
+#  - CLUSTER_TOKEN - the basic auth string as "username:password"
+#  - DNSIMPLE_TOKEN - an api key for a dnsimple account with a zone for proofs.filecoin.io
+#
+# Optional: you can override the input dir by passing a path as the first param.
+#
+# Usage:
+#   CLUSTER_TOKEN="user:pass" DNSIMPLE_TOKEN="xyz" ./pin-params.sh
+#
