                     You can also just list the five forms using slashes, eg. {/ze/zem/zir/zirs/zirself=ze/zem/zir/zirs/zirself}.
                     Keep in mind that <strong>all five forms</strong> are required in that case, otherwise the app can only guess what exactly you mean.

                     We're not planning to support fully customisable colours (like picking <em>just any</em> hex code)
                     because we'd rather hand-pick them to ensure they have enough contrast, distinguishability,
                     and a dark mode version – for the cards to be readable and accessible.

+                    The pronunciation uses the {https://en.wikipedia.org/wiki/International_Phonetic_Alphabet=International Phonetic Alphabet (IPA)},
+                    which uses special characters to describe the pronunciation in a way
+                    that it works for several languages.
+                    This also means that in most cases the pronunciation written down in IPA
+                    does not match the written spelling.
+                - >
+                    Please check that your inputted IPA contains valid characters.
+                    For example, there are no upper case letters in IPA.
+                - >
+                    If you are certain that your IPA is theoretically correct,
+                    it might be that our voice synthesizer does not correctly process the IPA.
+                    Some symbols also appear to be ignored, e.g. some length symbols or stresses.
+                    We still recommend to use the correct IPA even if the voice syntesizer produces a result that is
+                    slightly off, that way your intent is still visible in the written IPA.
+                    You can view {https://docs.aws.amazon.com/polly/latest/dg/supported-languages.html=a list of supported phonemes}
+                    per language to check whether the voice syntesizer lacks support.
