+## New repository
+
+We have a [dataset template](https://data.neuro.polymtl.ca/datasets/template) that we use for new repositories. When someone at the lab asks for a new dataset on <https://data.neuro.polymtl.ca/>, the steps to take are:
+
+1. Make sure they've opened [an issue in data-management](https://github.com/neuropoly/data-management/issues) with the name they want. Note that we only use **lowercase letters** and **hyphens** (no underscores).
+2. Log in to Neurogitea and go to [the repository creation page](https://data.neuro.polymtl.ca/repo/create?org=2). Then:
+   1. Select the organization "NeuroPoly datasets" as owner.
+   2. Fill in the repository name.
+   3. "Make Repository Private" should already be checked.
+   4. Select "datasets/template" as the template.
+   5. For template items, check the box for "Git Content (Default Branch)".
+   6. Click "Create Repository".
+3. In the new repository, click "Watch" so that at least one admin gets notifications (that is, you).
+4. Give write access to the requesting student:
+   1. Go to the repository's "Settings" tab.
+   2. Select "Collaborators" from the left-hand menu.
+   3. Search for the student's name and click "Add Collaborator".
+   4. Make sure the student's Neurogitea user account contains their actual human-readable name ("Site Administration" -> "User Accounts" -> search for the user -> edit).
+5. Reply on the original [data-management issue](https://github.com/neuropoly/data-management/issues) that you've created the repo and given them write access, with a link to the repo.
