 # Budgeteer
 
-Budgeting Web-Application
+Budgeting Web-Application written in Go and inspired by [YNAB](https://youneedabudget.com).
+
+## Getting started
+
+The fastest way to get up and running quickly, is using docker-compose. Just download the [docker-compose.yml](https://git.javil.eu/jacob1123/budgeteer/src/branch/master/docker/docker-compose.yml) to some empty directory and run `docker-compose up -d`. This starts budgeteer, a postgres database and an adminer instance. The latter is optional and can be removed from the docker-compose.yml.
+
+## Known issues
+
+Currently the application is usable when importing from YNAB via their CSV export. All balances should match the balances from YNAB. There are even unit-tests that confirm that using my personal budget.
+
+For people wishing to start fresh in Budgeteer, there currently are some blockers though:
+- The ability to create new accounts and categories is missing (#59)
+
+## Contributing
+
+If you're willing to help, please check the issues for [help-wanted labels](https://git.javil.eu/jacob1123/budgeteer/issues?labels=4). Just using Budgeteer and reporting any issues is although very helpful.
