+# Generating a new client 
+
+Every time
+
+
+1. Create a new branch `git checkout -b new_branch_name`
+2. Install openapi-generator
+
+```npm install @openapitools/openapi-generator-cli -g```
+
+2. Place the latest swagger.json in `./generate/swagger.json`
+
+3. Remove the current files except the `token.py` file
+
+```
+mv data_bridges_client/token.py .
+rm -rf tests docs data_bridges_client
+mkdir data_bridges_client
+mv ./token.py data_bridges_client/
+```
+
+5. Generate the client by running this command from the root of the repository. We pin the version to 5.4.0 as python templates from more recent versions don't seem to work.
+```
+openapi-generator-cli version-manager set 5.4.0
+openapi-generator-cli generate -g python -i generate/swagger.json -o . --package-name data_bridges_client --git-user-id WFP-VAM --git-repo-id DataBridgesAPI
+```
+4. Manually revert changes to `setup.py` and `README.md`. These relate to additional functionality we developed to handle the WFP token refresh workflow.
+5. Commit, push and open a PR into `dev` for review.
