▶ After pip install, type one command: openestimate

That's the only thing you need to remember. It prints a welcome, asks press o + Enter to open the app in your browser, then starts the server at http://127.0.0.1:8080.

Quick Start

pip install --upgrade openconstructionerp
openestimate                 # welcome screen + o-to-open-browser + server

Requires Python 3.12+. Check with python --version.

That's the whole first run. The bare openestimate command:

1. Prints a welcome with links to docs, issues, and the community chat.
2. Creates a local SQLite database and data folder under ~/.openestimate/.
3. Starts the server at http://127.0.0.1:8080 and opens your browser.

Prefer explicit steps? Run them yourself:

openestimate init-db         # create the local database
openestimate serve           # start the server
openestimate doctor          # health check if anything looks wrong
openestimate welcome         # re-print the welcome screen + support links
