+## Getting Started
+
+1. Launch an interactive playground
+
+  ```sh
+  ./orcli run --interactive
+  ```
+
+2. Create OpenRefine project `duplicates` from comma-separated-values (CSV) file
+
+  ```sh
+  orcli import csv "https://git.io/fj5hF" --projectName "duplicates"
+  ```
+
+3. Show OpenRefine project's metadata
+
+  ```sh
+  orcli info "duplicates"
+  ```
+
+4. ~~~Remove duplicates~~~
+
+5. Export data from OpenRefine project to tab-separated-values (TSV) file `duplicates.tsv`
+
+  ```sh
+  orcli export tsv "duplicates" --output "duplicates.tsv"
+  ```
+
+6. Write out your session history to file `example.sh` (and delete the last line to remove the history command)
+
+  ```sh
+  history -a "example.sh"
+  sed -i '$ d' example.sh
+  ```
+
+7. Exit playground
+
+  ```sh
+  exit
+  ```
+
+8. Run batch process
+
+  ```sh
+  ./orcli run example.sh
+  ```
+
+9. Cleanup example files
+
+  ```sh
+  rm duplicates.tsv
+  rm`example.sh
+  ```
