curl -fsSL https://bordeux.github.io/apt-repo/gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/bordeux-archive-keyring.gpg

# Add repository
echo "deb [signed-by=/usr/share/keyrings/bordeux-archive-keyring.gpg] https://bordeux.github.io/apt-repo stable main" | sudo tee /etc/apt/sources.list.d/bordeux.list

sudo mv tmpltool /usr/local/bin/
chmod +x /usr/local/bin/tmpltool
```

## Using Docker

Docker images are available for extracting the binary into your own images (similar to gomplate pattern):

**In Your Dockerfile:**
```dockerfile
# Multi-stage build to copy tmpltool binary
FROM ghcr.io/bordeux/tmpltool:latest AS tmpltool

FROM alpine:latest
# Copy the binary from the tmpltool image
COPY --from=tmpltool /tmpltool /usr/local/bin/tmpltool

# Now use tmpltool in your build process
COPY config.tmpltool /app/
RUN tmpltool /app/config.tmpltool -o /app/config.json --validate json
```

**Available Tags:**
- `latest` - Latest stable release
- `v1.x.x` - Specific version tags
- Multi-arch support: `linux/amd64`, `linux/arm64`

**For Local Testing:**
```bash
# Extract binary to local system
docker create --name tmpltool-tmp ghcr.io/bordeux/tmpltool:latest
docker cp tmpltool-tmp:/tmpltool ./tmpltool
docker rm tmpltool-tmp
chmod +x ./tmpltool
./tmpltool --version
```

## From Source

```bash
cargo install --path .
```

Or build manually:

```bash
cargo build --release
# Binary will be at: ./target/release/tmpltool
```
