 In non-orchestration mode, participants drive participation. Hence, participants should bring their dataset along with compute.
 
 ### Step 1: create a design
-```
+```bash
 flamectl create design adult -d "census income dataset example in non-orchestration mode"
 ```
 
 ### Step 2: create a schema for design mnist
-```
+```bash
 flamectl create schema schema.json --design adult
 ```
 
 ### Step 3: create (i.e., add) mnist code to the design
 
-```
+```bash
 flamectl create code adult.zip --design adult
 ```
 Note: to understand relationship between schema and code, unzip adult.zip and check the folder structure in it.
 
 ### Step 4: create a job
-```
-
+```bash
+flamectl create job job.json
 ```
 If successful, this command returns the id of the created job.
 For example,
 ```bash
-$ flamectl create job job.json
 New job created successfully
