+# crystfel
+
+Data processing for serial (femtosecond) crystallography at FELs and
+synchrotrons: indexamajig, partialator, process_hkl, cell_explorer,
+the CrystFEL GUI and friends.
+
+- Upstream: https://www.desy.de/~twhite/crystfel/
+- License: GPLv3
+
+## How it is built
+
+Source tarball from https://desy.de/~twhite/crystfel/ (sha256-verified),
+built with meson per upstream INSTALL.md:
+`meson setup build --prefix=$PREFIX && meson compile -C build && meson install -C build`.
+
+Upstream warns: do NOT have any conda environment active while building.
+Build-host prerequisites (meson, ninja, gcc, and the C libraries: hdf5,
+gsl, and optionally cairo/gdk-pixbuf/gtk for the GUI, fftw, zmq) must be
+available on the Ra build node -- add `build_requires:` entries in
+`files/config.yaml` if matching Ra modules are needed.
+
+Loading the module puts `$PREFIX/bin` on `PATH`.
+
+## Building on Ra
+
+```sh
+module use unstable && module load modbuild/2.1.2
+cd crystfel
+modbuild build 0.13.0
+module use MX unstable && module load crystfel/0.13.0 && indexamajig --version
+```
+
+## Verifying the install
+
+```sh
+module use MX unstable && module load crystfel/0.13.0
+which indexamajig
+indexamajig --version
+cell_explorer         # GUI check, needs X
+```
+
+## Adding a new version
+
+Add the version under `versions:` and its tarball sha256 under `shasums:`
+in `files/config.yaml`, then on a Ra login node:
+`modbuild build <version>` (modbuild/2.1.2).
