+# Cloning from any tailnet machine
+
+## Prerequisites
+- The remote machine must be on your tailnet (registered + can ping `100.85.x.x`)
+- You must have an account on the Gitea instance (`http://git.klud.top`)
+- You must have an SSH key on the remote machine (`ssh-keygen` if you don't)
+
+## Step 1: Add your SSH key to Gitea
+1. Open `http://git.klud.top/user/settings/keys` in browser
+2. Paste the content of `~/.ssh/id_ed25519.pub` (or `id_rsa.pub`)
+3. Click "Add Key"
+
+## Step 2: Test SSH reachability
+```bash
+ssh -T git@thunderobot -p 222
+# Expected output: "Hello from Gitea!\n\nPlease come over!"
+# If asked about fingerprint, type "yes" and press Enter
+```
+
+## Step 3: Clone a repo
+```bash
+# Using tea CLI
+tea repos clone --git-protocol ssh danchie/tekton
+
+# Or plain git
+git clone git@thunderobot:222/danchie/tekton.git
+```
+
+## Troubleshooting
+- `ssh: connect to host thunderobot port 222: Connection refused`
+  → Ensure the remote machine has `tailscale ping thunderobot` resolving to `100.93.226.13`
+  → Ensure the host's port `222` is reachable from the remote (it's bound to `0.0.0.0:222` in Docker)
+
+- `Permission denied (publickey)`
+  → Your SSH key wasn't added via Gitea web UI
+  → Run `ssh-add ~/.ssh/id_ed25519` if you use an agent
+
+- `Host key verification failed`
+  → Run `ssh -T git@thunderobot -p 222` interactively once to accept the fingerprint
+
+## HTTPS is disabled
+`DISABLE_HTTP_GIT = true` is set on the server. All clones MUST use SSH.
+If you need to fetch via HTTPS for CI or other non-ssh environments, this must be remapped.

+
+## SSH setup for cloning
+
+All clones **must use SSH** over Tailscale. HTTPS is disabled on this instance.
+
+Guides by operating system:
+
+- [Linux](https://git.klud.top/danchie/tekton/wiki/SSH-Setup-Linux)
+- [macOS](https://git.klud.top/danchie/tekton/wiki/SSH-Setup-macOS)
+- [Windows](https://git.klud.top/danchie/tekton/wiki/SSH-Setup-Windows)
+
+Quick verification after setup:
+```bash
+ssh -T git@thunderobot -p 222
+```
+
+Once verified, clone:
+```bash
+git clone git@thunderobot:222/danchie/tekton.git
+```
