Hey found this and I bet it'll help a lot of folks!
It's the "Standards of Care" for trans folks (and non-binary folks) and covers a lot of how to get started with HRT (like what is needed) and other health care trans issues.
I'm reading and using it myself for Germany right now, but there are other languages available!
Especially if you like to know what "informed consent" requires and entails, it's a good source.
For preparation on acquiring it yourself for example (like I do right now)
Small, friendly instance for friends. Come join us and be cute and soft and small and cute.
