The "other requirements" are listed in the [reproducible builds readme](https://github.com/sparrowwallet/sparrow/blob/master/docs/reproducible.md#other-requirements) already. However when trying to quickly build the binaries and follow the main README instructions, the last paragraph about "[m]ore detailed instructions on reproducing the binaries are provided" can be overlooked very easily. Because the paragraph is about the specific topic "reproducible builds" and not building the binaries from source in general.
This tiny Readme edit would, I think, have preempted the confusion that prompted #263 . I thought that the general install installed a global command, and didn't think, for some time, to run from within the directory. Dumb, but figured clarifying the doc would be better than just figuring it out silently on my own.
