Issue with Homebrew installation in README

[ehis]

Attempting to install cog via Homebrew fails.

~[130]►brew install replicate/tap/cog                                                                                                                39.39s 11:09
Warning: No available formula or cask with the name "replicate/tap/cog". Did you mean replicate/tap/pget?

Took a look at the tap repo and there's only pget & replicate

Good catch @ehis ! Working on it here: replicate/homebrew-tap#30

@ehis try now:

brew install --cask replicate/tap/cog

@ehis try now:

brew install --cask replicate/tap/cog

@markphelps works now! Thanks for the fix
