+### CrowdIn Glossary
+
+We have a [CrowdIn Glossary](crowdin-glossary.json) that has some terms which are noted as shared or translateable across the project. If a term is missing, please add it! This glossary will automatically be used by CrowdIn to let translators know about each term when they come across them.
