+# Git SSH Key Setup for Gitea
+
+## Overview
+
+Git is now configured to use SSH key authentication for all operations with `git.mymx.me`.
+
+## SSH Key Details
+
+- **Location**: `/opt/ansible/secrets/ssh/ansible`
+- **Type**: ed25519
+- **Fingerprint**: `SHA256:mkgq5V567C/CJas9nbP16kNzzVqs7z7k2X90qdP0QXE`
+- **User**: `ansible@mymx.me`
+- **Passphrase**: Stored in `secrets/ssh/README.md`
+
+## Configuration
+
+### Git Configuration
+
+Git has been configured to use the SSH key:
+
+```bash
+git config core.sshCommand "ssh -i /opt/ansible/secrets/ssh/ansible"
+```
+
+### SSH Agent Initialization
+
+An automatic SSH agent initialization script has been created at `/opt/ansible/.ssh-agent-init`.
+
+To use in new shells, add to your shell profile:
+
+```bash
+source /opt/ansible/.ssh-agent-init
+```
+
+This script will:
+1. Start ssh-agent if not running
+2. Load the ansible SSH key with passphrase automatically
+3. Persist the agent across shell sessions
+
+## Usage
+
+### Current Shell
+
+In your current shell, source the initialization script:
+
+```bash
+source /opt/ansible/.ssh-agent-init
+```
+
+### Git Operations
+
+All standard git operations now work with SSH authentication:
+
+```bash
+# Fetch updates
+git fetch origin
+
+# Pull changes
+git pull origin master
+
+# Push commits
+git push origin master
+
+# Check remote
+git ls-remote origin
+```
+
+### Manual SSH Key Management
+
+If you need to manually manage the SSH key:
+
+```bash
+# Check loaded keys
+ssh-add -l
+
+# Add key manually (will prompt for passphrase)
+ssh-add /opt/ansible/secrets/ssh/ansible
+
+# Remove key from agent
+ssh-add -d /opt/ansible/secrets/ssh/ansible
+```
+
+## Troubleshooting
+
+### "Could not open a connection to your authentication agent"
+
+Run the initialization script:
+
+```bash
+source /opt/ansible/.ssh-agent-init
+```
+
+### "Permission denied (publickey)"
+
+Ensure the key is loaded in ssh-agent:
+
+```bash
+ssh-add -l
+```
+
+If not listed, source the initialization script or add manually.
+
+### Verify SSH Connection
+
+Test SSH connection to Gitea:
+
+```bash
+ssh -T git@git.mymx.me -p 2222 -i /opt/ansible/secrets/ssh/ansible
+```
+
+## Security Notes
+
+- Private key is stored in `secrets/` directory (should be in separate git repository)
+- Passphrase is documented in `secrets/ssh/README.md`
+- SSH key has read/write access to ansible repositories on git.mymx.me
+- Key was uploaded to Gitea with Key ID: 5
+
+## References
+
+- Passphrase details: `secrets/ssh/README.md`
+- SSH config: `~/.ssh/config`
+- Git config: `.git/config` (core.sshCommand)
