 # FlightData
 Flight data (log files) for model validation
+
+## Use as a Julia Artifact
+
+This repository can be used as a [Julia artifact](https://pkgdocs.julialang.org/v1/artifacts/) for downloading flight data in packages or scripts.
+
+### In a project
+
+Add the following to your `Artifacts.toml`:
+
+```toml
+[flight_data]
+git-tree-sha1 = "9ac5fb6863ecdce392c784302e2d3169918a23f2"
+
+    [[flight_data.download]]
+    sha256 = "7c93b77c8fe3a3a78fb8268699c51d200e305736cedce6c01b67d21ef6f7d66e"
+    url = "https://github.com/OpenSourceAWE/FlightData/releases/download/v0.1.0/flight_data.tar.gz"
+```
+
+Then access the data in Julia:
+
+```julia
+using ArtifactUtils  # or LazyArtifacts
+datadir = @artifact "flight_data"
+# datadir now points to the extracted flight_data/ folder
+```
+
+### Manual download
+
+The tarball can also be downloaded and extracted manually:
+
+```bash
+curl -LO https://github.com/OpenSourceAWE/FlightData/releases/download/v0.1.0/flight_data.tar.gz
+tar -xzf flight_data.tar.gz
+```
