+## As final user...
+
+How to use:
+```bash
+pip install longitude
+```
+
+Or:
+```bash
+pipenv install longitude
+```
+
+Or:
+```bash
+poetry add longitude
+```
+
+Or install from GitHub:
+```bash
+pip install -e git+https://github.com/GeographicaGS/Longitude#egg=longitude
+```
+
+## As developer...
+
+### First time
+
+1. Install ```poetry``` using the [recommended process](https://github.com/sdispater/poetry#installation)
+    1. poetry is installed globally as a tool
+    1. It works along with virtualenvironments
+1. Create a virtual environment for Python 3.x (check the current development version in ```pyproject.toml```)
+    1. You can create it wherever you want but do not put it inside the project
+    1. A nice place is ```$HOME/virtualenvs/longitude```
+1. Clone the ```longitude``` repo
+1. `cd` to the repo and:
+    1. Activate the virtual environment: `. ~/virtualenvs/longitude/bin/activate`
+    1. Run `poetry install`
+1. Configure your IDE to use the virtual environment
+
+### Daily
+
+1. Remember to activate the virtual environment 
+
+### Why Poetry?
+
+Because it handles development dependencies and packaging with a single file (```pyproject.toml```), which is [already standard](https://flit.readthedocs.io/en/latest/pyproject_toml.html).
+
+## Sample scripts
+
+These are intended to be used with real databases (i.e. those in your profile) to check features of the library. They must be run from the virtual environment.
+
+## Testing and coverage 
+
+The [```pytest-cov```](https://pytest-cov.readthedocs.io/en/latest/) plugin is being used. Coverage configuration is at ```.coveragerc``` (including output folder).
+
+You can run something like: ```pytest --cov-report=html --cov=core core``` and the results will go in the defined html folder.
+
+There is a bash script called ```generate_core_coverage.sh``` that runs the coverage analysis and shows the report in your browser.
