Issue template directory?

Hello,

I would like to have a custom issue template for specific project.

But I don’t find the right path.

I read the doc, but don’t understand it.

My systemd file

[Unit]
Description=Gitea (Git with a cup of tea)
Documentation=https://coredns.io/tags/documentation/
After=syslog.target
After=network.target

[Service]
Restart=always
RestartSec=10
Type=simple
User=git
Group=git
RuntimeDirectory=gitea
EnvironmentFile=/etc/default/gitea
WorkingDirectory=/var/lib/gitea
ExecStart=/bin/sh -c "/usr/bin/gitea $ARGS 1>>/var/log/gitea/gitea.log 2>&1"
ExecStartPost=/bin/sh -c "echo $MAINPID > /run/gitea/gitea.pid"
ExecReload=/bin/kill -HUP $MAINPID
Environment=USER=git HOME=/var/lib/gitea GITEA_WORK_DIR=/var/lib/gitea
TimeoutStopSec=20s
PIDFile=/run/gitea/gitea.pid
SendSIGKILL=no
LimitNOFILE=8192

[Install]
WantedBy=multi-user.target

the passwd file:

git:x:109:1001::/var/lib/gitea:/bin/false

and in /var/lib/gitea/gitea-repositories/xxxxx/name_project.git

I create directory .gitea/and put .md in.

I tried in :
/var/lib/gitea/.gitea/issue_template
/var/lib/gitea/.gitea/issue_template.md

Sorry not to find the solution by myself… Need help.
Thanks
