-# Examples
+# Instantiating this configuration in another account
 
-Create directories with specific examples and describe how to use the module in a variety of ways.
+## Prerequisites
+
+1. In the target account, be sure that `GIT-ROOT/.tf-control` shows the `TERRAFORM` variable set
+to `terraform_current`.
+1. Add service linked roles to `common/` (see module examples)
+1. Import the account GPG key
+   ```
+   # cd TARGET-GIT-ROOT
+   cd init/gpg-setup
+   git-secret reveal -f
+   gpg --import tf-*.gpg.asc tf-*.secret-key
+   ```
+
+## Steps to Clone
+
+* Create the approriate directory in the target account
+
+```script
+# cd TARGET-GIT-ROOT
+# make new branch and checkout
+mkdir common/west/apps/ditd-darhts-s3-transfer
+```
+
+* Rsync (not cp)
+
+```
+# cd SOURCE # GitHub location of source: [here](https://github.e.it.census.gov/terraform/260949450014-adsd-dapps-ite-gov/tree/master/common/west/apps/ditd-darhts-s3-transfer)
+rsync -avRWH ./ TARGET-GIT-ROOT/common/west/apps/ditd-darhts-s3-transfer
+```
+
+* Cleanup new directory
+
+```
+# cd TARGET-GIT-ROOT/common/west/apps/ditd-darhts-s3-transfer
+tf-run superclean
+rm -rf access_keys *.secret
+git-secret add api.txt variables.api.auto.tfvars
+```
+
+## Steps to setup
+
+* Work in target directory
+
+```
+# cd TARGET-GIT-ROOT/common/west/apps/ditd-darhts-s3-transfer
+```
+
+* Populate files with values
+
+Add proper information for the new environment, new settings into the files
+  * api.txt
+  * variables.api.auto.tfvars
+  * variables.auto.tfvars
+
+You can use the variables.auto.tfvars.TEMPLATE file to change just the environent, like this:
+
+```
+sed -e "s/{ENVIRONMENT}/qa/g" variables.auto.tfvars.TEMPLATE > variables.auto.tfvars
+```
+
+* Check the `tags.*.yml` for proper values
+
+* Process and prepare for PR
+
+```
+tf-run init
+tf-run plan
+git-secret hide -m
+git add .
+```
+
+* Commit
+
+Commit the branch, push the commit, do the PR, upload the `tf-plan` log and add the
+`tf-plan summary` to the PR body.
+
+## Apply and beyond
+
+* Once you have a merged PR, you may apply.  You'll have a few additional steps post-apply
+that need to be again submitted as git PRs.
+
+
+# still in your branch
+```
+git pull origin master
+tf-run apply
+```
+
+* Add access key to git-secret
+
+```
+git-secret add access_keys/*/access_key.yml
+git-secret hide -m
+git add access_keys
+```
+
+* Commit -a (to get git-secret changes)
+
+```
+git commit -a -m "insert message"
+git push
+```
+
+and again do a PR to merge in all the new files generated.
+
+You will need to distribute the `access_key.yml` file (encrypted zip) to the POC.
