 ### Install dependencies
 
 ```bash
-pip install -r requirements.txt
+pip install -e .[dev]
 ```
 
+This will install dependencies for developing, but won't install this project as an library.
+
+To build the wheel files:
+
+```bash
+python -m build
+```
+
+The wheel file should be located under `dist` folder.
+You can use `pip install /path/to/wheel.whl` to install this library.
+
 ### Use as a library
 
-Use this URL to add this project as a dependency (NOTE - TODO: update instructions for ForgeJo repo after pulp repo is up & running for python artifacts)
-
-
-```
-git+https://git.cleverthis.com/cleverthis/clevermicro/amq-adapter-python.git@develop#egg=amq_adapter
-```
-
-> Hint: use `git config --global credential.helper store` to enable Git credential manager
-> so you don't have to re-enter the gitlab credential everytime.
-
-Then:
+The library has been published to pulp registry at `https://pkg.cleverthis.io/pypi/clevermicro/amq-adapter-python/`.
+Configure the dependency `amq_adapter` with the above registry using
+your build tools, then:
 
 ```python
 from amqp.service import amq_service
+
+# start using the lib
 ```
 
 #### How to build distributable Wheel archive
 
-install project requirements
-`pip install -r requirements.txt`
-
-install distribution archive requirements 
-`pip install setuptools wheel build`
+install project requirements and dev dependencies
+`pip install -e .[dev]`
 
 update version in:
 `pyproject.toml`
 
+> For dev versions, keep the `-dev` suffix. The pipeline will replace it with a unique timestamp,
+> act like maven SNAPSHOT versions.
+
 build the distributable archive (will be located in `./dist` directory)
 `python -m build --wheel`
