So I tried installing and got this error:
Using version 0.3.0 for v17development/flarum-blog
./composer.json has been created
Running composer update v17development/flarum-blog
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires v17development/flarum-blog 0.3.0 -> satisfiable by v17development/flarum-blog[v0.3.0].
- v17development/flarum-blog v0.3.0 requires flarum/core 0.1.0-beta.16 -> found flarum/core[dev-master, v0.1.0-beta.16, 0.1.x-dev (alias of dev-master)] but it does not match your minimum-stability.
Installation failed, deleting ./composer.json.
What do I need to do to fix this?
