+# New Google Client Library Generation
+
+The script allows you to create a new client library module in the
+google-cloud-java monorepo.
+
+**This tool is for repository maintainers only. Not for library users.**
+
+## Prerequisites
+
+This section is only needed for the first run of this script. If it's already
+done, go to "Run client generation script" section.
+
+
+### Environment
+
+Use Linux environment.
+
+Install Docker.
+
+### Checkout google-cloud-java repository
+
+```
+$ git clone https://github.com/googleapis/google-cloud-java
+```
+
+### Install pyenv
+
+Install pyenv
+
+```
+curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer \
+| bash
+```
+
+Follow the instruction in the output above to append lines in `$HOME/.bashrc`.
+Logout the shell and login again.
+
+Confirm pyenv installation succeeded:
+
+```
+suztomo@suztomo:~$ pyenv
+pyenv 2.3.4
+Usage: pyenv <command> [<args>]
+
+Some useful pyenv commands are:
+   activate    Activate virtual environment
+   commands    List all available pyenv commands
+   deactivate   Deactivate virtual environment
+...
+```
+
+### Install Python 3.9 via pyenv
+
+```
+suztomo@suztomo:~$ pyenv install 3.9.13
+Downloading Python-3.9.13.tar.xz...
+-> https://www.python.org/ftp/python/3.9.13/Python-3.9.13.tar.xz
+Installing Python-3.9.13...
+WARNING: The Python sqlite3 extension was not compiled. Missing the SQLite3 lib?
+Installed Python-3.9.13 to /usr/local/google/home/suztomo/.pyenv/versions/3.9.13
+```
+
+Conform `python3.9` command is available:
+
+```
+$ pyenv local 3.9.13
+$ which python3.9
+/usr/local/google/home/suztomo/.pyenv/shims/python3.9
+```
+
+### Install Python packages
+
+At the root of google-cloud-java repository clone, run:
+
+```
+$ python3.9 -m pip install -r generation/new_client/requirements.txt
+```
+
+## Run client generation script
+
+You will run new-client.py script with the following parameters.
+Collect them from the ticket before running the command.
+
+### API short name
+
+For convenience of the subsequent commands, define a variable for API short name.
+Get the value from the DevRel Services page (Example: `apikeys`):
+
+### proto path
+
+The script takes "proto path" parameter. This is path from google3's root to the
+directory that contains versions (e.g., "v1" or "v2"). For example, if we
+have 
+
+> Link to protos: http://google3/google/api/apikeys/v2/apikeys.proto
+
+then the "proto path" value we supply to the command is "google/api/apikeys".
+
+### Name pretty
+
+Pick name from the display name in the DevRel Services site.
+For example, "API Keys API" in
+https://devrel.corp.google.com/admin/products/479.
+
+### Product Docs
+
+Find product document URL in the DevRel Services site.
+For example, "https://cloud.google.com/api-keys/" in
+https://devrel.corp.google.com/admin/products/479.
+
+### API description
+
+Find the short description of the API. Usually the first sentence in the product
+document above.
+
+### Release level
+
+The first client generation is always "preview".
+
+### Transport
+
+Transport layer. Use "grpc".
+
+
+### Language
+
+Use "java"
+
+### Monorepo URL
+
+Use "https://github.com/googleapis/google-cloud-java"
+
+
+### Example arguments
+
+Run `new-client.py` with the arguments above:
+
+```
+$ cd generation/new_client
+$ python3.9 new-client.py generate \
+  --api_shortname=apikeys \
+  --proto-path=google/api/apikeys \
+  --name-pretty="API Keys API" \
+  --product-docs="https://cloud.google.com/api-keys/" \
+  --api-description="API Keys lets you create and manage your API keys for your projects." \
+  --release-level=preview \
+  --transport=grpc \
+  --language=java \
+  --monorepo-url="https://github.com/googleapis/google-cloud-java"
+```
+
+The command creates `workspace` directory in which it prepares the changes for
+the new module in the monorepo. At the end (~ 10 minutes), it tells you to
+create a pull request in the monorepo:
+
+```
+...
+Prepared new library in workspace/monorepo/java-apikeys
+Please create a pull request from that directory:
+  $ cd /usr/local/google/home/suztomo/google-cloud-java/generation/new_client/workspace/monorepo
+  $ gh pr create --title 'feat: [apikeys] new module for apikeys'
+```
+
+Create a pull request from the change.
+
+# Principles
+
+The script should finish creating a pull request even when the newly created
+module fails to compile. This gives the user flexibility to fix things in the
+created pull request.
+
