+# Initiate a new TSC vote
+
+For yes/no questions, the TSC will typically use GH reactions to conduct a vote,
+and use this workflow only for questions with several candidate answers, or to
+e.g guarantee vote secrecy until the vote is counted.
+
+## From the GitHub web UI
+
+1. Edit the [`_EDIT_ME.yml`](./_EDIT_ME.yml) file, fill in the info related to
+   vote to open.
+2. When committing, chose to commit to new branch and open a Pull Request to
+   discuss the vote terms with the whole TSC.
+3. Once the PR has approvals, merge it on the `initiateNewVote` branch (GHA
+   should have set that as the target/base branch automatically).
+4. GHA will open a new PR with the vote initiated.
+
+## From the CLI
+
+This method is not recommended.
+
+1. Edit the [`_EDIT_ME.yml`](./_EDIT_ME.yml) file, fill in the info related to
+   vote to open.
+2. Commit your changes.
+3. Push that to the remote `refs/heads/initiateNewVote`.
+4. GHA will open a new PR with the vote initiated.

+# To initiate a new vote, you need to open a PR modifying this file. The vote

+
+# 1. Select a subject for the vote. This can be a question addressed to the TSC
+#    voting members.

+  Negative scores are allowed, only the order matters.
+  You can tie two or more proposals if you have no preference.
+  To abstain, keep all the propositions tied.

+#    question, and should leave as little room to interpretation as possible. Do
+#    not list candidates that don't have a champion, there should be a
