+# Contributing
+
+Thank you for taking the time to make a contribution to Stack Orchestrator.
+
+## Install (developer mode)
+
+Suitable for developers either modifying or debugging the orchestrator Python code:
+#### Prerequisites
+In addition to the binary install prerequisites listed above, the following are required:
+1. Python venv package
+   This may or may not be already installed depending on the host OS and version. Check by running:
+   ```
+   $ python3 -m venv
+   usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear] [--upgrade] [--without-pip] [--prompt PROMPT] ENV_DIR [ENV_DIR ...]
+   venv: error: the following arguments are required: ENV_DIR
+   ```
+   If the venv package is missing you should see a message indicating how to install it, for example with:
+   ```
+   $ apt install python3.10-venv
+   ```
+#### Install
+1. Clone this repository:
+   ```
+   $ git clone (https://github.com/cerc-io/stack-orchestrator.git
+   ```
+4. Enter the project directory:
+   ```
+   $ cd stack-orchestrator
+   ```
+5. Create and activate a venv:
+   ```
+   $ python3 -m venv venv
+   $ source ./venv/bin/activate
+   (venv) $
+   ```
+6. Install the cli in edit mode:
+   ```
+   $ pip install --editable .
+   ```
+7. Verify installation:
+   ```
+   (venv) $ laconic-so
+   Usage: laconic-so [OPTIONS] COMMAND [ARGS]...
+
+    Laconic Stack Orchestrator
+
+   Options:
+    --quiet
+    --verbose
+    --dry-run
+    -h, --help  Show this message and exit.
+
+   Commands:
+    build-containers    build the set of containers required for a complete...
+    deploy-system       deploy a stack
+    setup-repositories  git clone the set of repositories required to build...
+   ```
+
+#### Build a zipapp (single file distributable script)
+Use shiv to build a single file Python executable zip archive of laconic-so:
+1. Install [shiv](https://github.com/linkedin/shiv):
+   ```
+   $ (venv) pip install shiv
+   $ (venv) pip install wheel
+   ```
+1. Run shiv to create a zipapp file:
+   ```
+   $ (venv)  shiv -c laconic-so -o laconic-so .
+   ```
+   This creates a file `./laconic-so` that is executable outside of any venv, and on other machines and OSes and architectures, and requiring only the system Python3:
+1. Verify it works:
+   ```
+   $ cp stack-orchetrator/laconic-so ~/bin
+   $ laconic-so
+      Usage: python -m laconic-so [OPTIONS] COMMAND [ARGS]...
+
+      Laconic Stack Orchestrator
+
+   Options:
+      --quiet
+      --verbose
+      --dry-run
+      -h, --help  Show this message and exit.
+
+   Commands:
+      build-containers    build the set of containers required for a complete...
+      deploy-system       deploy a stack
+      setup-repositories  git clone the set of repositories required to build...
+   ```
