+# mcl
+
+Minecraft launcher created out of dissatisfaction with other clients
+
+## What's it do?
+
+- download many versions
+- download assets
+- download libraries
+
+## What's it *not* do?
+
+- select the correct libraries for the version
+- set up natives (will only support linux)
+- get an authentication token (I will not support Mojang accounts)
+- instances
+- ...launch the game :/
+
+## Why not use the regular launcher?
+
+- closed source
+- really buggy, for some reason
+- I'd call it bloated but honestly this is probably slower
+
+## Why not a third party launcher?
+
+GDLauncher sounds great but it crashes for me and MultiMC's management sucks; they're terrible about custom builds and branding. I don't know of any other launchers and quite frankly I think I should just torture myself by making one.
+
+## I want to steal your code.
+
+I'm honored, I guess? The code is public domain. There's no license file, so just put in your own and pretend I put it there.
