 # Contributing to podman-compose
 
+## Who can contribute? 
+
+- Users that found a bug
+- Users that wants to propose new functionalities or enhancements
+- Users that want to help other users to troubleshoot their environments
+- Developers that want to fix bugs
+- Developers that want to implement new functionalities or enhancements
+
+## Branches
+
+Please request your PR to be merged into the `devel` branch. 
+Changes to the `stable` branch are managed by the repository maintainers.
+
+## Development environment setup
+
+Note: Some steps are OPTIONAL but all are RECOMMENDED.
+
+1. Fork the project repo and clone it
+```shell
+$ git clone https://github.com/USERNAME/podman-compose.git
+$ cd podman-compose
+```
+1. (OPTIONAL) Create a python virtual environment. Example using [virtualenv wrapper](https://virtualenvwrapper.readthedocs.io/en/latest/): 
+```shell
+mkvirtualenv podman-compose
+```
+2. Install the project runtime and development requirements   
+```shell
+$ pip install '.[devel]'
+```
+3. (OPTIONAL) Install `pre-commit` git hook scripts (https://pre-commit.com/#3-install-the-git-hook-scripts)
+```shell
+$ pre-commit install
+```
+4. Create a new branch, develop and add tests when possible
+5. Run linting & testing before commiting code. Ensure all the hooks are passing.
+```shell
+$ pre-commit run --all-files
+```
+6. Commit your code to your fork's branch. 
+   - Make sure you include a `Signed-off-by` message in your commits. Read [this guide](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) to learn how to sign your commits 
+   - In the commit message reference the Issue ID that your code fixes and a brief description of the changes. Example: `Fixes #516: allow empty network`
+7. Open a PR to `containers/podman-compose:devel` and wait for a maintainer to review your work.

-An implementation of `docker-compose` with [Podman](https://podman.io/) backend.

 * `podman`
+* [podman dnsname plugin](https://github.com/containers/dnsname): It is usually found in the `podman-plugins` or `podman-dnsname` distro packages, those packages are not pulled by default and you need to install them. This allows containers to be able to resolve each other if they are on the same CNI network.
 * Python3
 * [PyYAML](https://pyyaml.org/)
 * [python-dotenv](https://pypi.org/project/python-dotenv/)

+## Alternatives
+
+As in [this article](https://fedoramagazine.org/use-docker-compose-with-podman-to-orchestrate-containers-on-fedora/) you can setup a `podman.socket` and use unmodified `docker-compose` that talks to that socket but in this case you lose the process-model (ex. `docker-compose build` will send a possibly large context tarball to the daemon)

+If you have legacy version of `podman` (before 3.1.0) you might need to stick with legacy `podman-compose` `0.1.x` branch.
 The legacy branch 0.1.x uses mappings and workarounds to compensate for rootless limitations.
 
-Modern podman versions (>=3.4) do not have those limitations and thus you can use latest and stable 1.x branch.
+Modern podman versions (>=3.4) do not have those limitations, and thus you can use latest and stable 1.x branch.

+If you are upgrading from `podman-compose` version `0.1.x` then we no longer have global option `-t` to set mapping type
