 This repository stories issue, pull request and merge request templates for Matrix AI
+
+GitHub templates are stored in `.github`. This repository must be placed under https://github.com/MatrixAI/.github. The `.github` repository name is essential for GitHub to recognise it as a special organisation-template repository.
+
+GitLab templates are stored in `.gitlab`. This repository must be selected as the templates repository under `Settings > General > Templates`.
+
+Note that template syntax differs by a little bit. In particular GitHub templates require a stanza at the beginning while GitLab templates use special slash commands. When updating the templates for GitHub or GitLab, ensure that it is also updated for the other system as well so we can have a consistent set of templates.
