+# Sequence returns input in hex format
+
+## Running
+
+Open three terminals and run the following commands:
+
+### The First Terminal
+
+```bash
+# start sth by executing command...
+scramjet-transform-hub
+
+# ...or use script
+cd transform-hub
+npm run start -P 8000
+```
+
+### The Second terminal
+
+```bash
+# go to 'hexdump' directory
+cd samples/hexdump
+
+# install dependencies
+npm install
+
+# transpile TS->JS and copy node_modules and package.json to dist/
+npm run build
+
+# deploy the Sequence from the dist/ directory, which contains transpiled code, package.json and node_modules
+si seq deploy dist
+# copy instance _id - you'll use this in 3rd terminal window
+
+# see the Instance output
+si inst output -
+```
+
+### The third terminal
+
+```bash
+# replace INSTANCE_ID with actual instance ID and pipe scramjet.ico as binary to instance input
+si inst input <INSTANCE_ID> scramjet.ico -t application/octet-stream
+
+# In another terminal
+si inst output <INSTANCE_ID>
+```
+
+Check output in second terminal to see hex format of scramjet.ico file.
+
+## Expected output
+
+```bash
