update “how to build“ section of Readme: move from .env to /my/variables

[florianjacob]

I'm currently in the progress of creating my own system-configuration repository with the build scripts from this repo. Now, the Readme states the following paragraph:

How to build

[…]
Some holograms include sensible information that has been left out of this public repo. This information is in my private clones of this repo only, in the top-level directory of the repo in a .env file. The env.example file shows which environment variables are expected to be defined by .env.

I inferred from your recent commits that you changed this to /my/variables, which is probably something like a .holoscript containing a lot of sed expressions which change the variables into the actual values or something like that.

Still, could you please update the documentation to explain what you're doing now exactly instead of the .env method?

Thanks alot for holo! 👍 😄

Wow, people are actually using this. Awesome!

I should really update the README, that's for sure. Will try to do so when I have some more time on my hands.

Oh, for reference, here's how the /my/variables looks, basically:

#!/bin/sed -f

s/\${GANDI_APIKEY}/noimnotactuallywritingtheapikeyhere/g
# and so on
