+# CCIMS Eclipse Plugin Api Bindings
+Generated java bindings for the ccims graphql api.
+
+## Submodule
+The folder [`graphql_java_gen`](graphql_java_gen) is a git submodule with the actual generator code and some necessary java classes.
+
+These java classes are copied to src-support during the generation.
+The copyright and license notice for these files can be found at [src-support/LICENSE.txt](src-support/LICENSE.txt).
+
+## Generating
+### Preparations
+Install `bash`, `ruby`, `gem` and `bundler`.
+Install project dependencies by executing `bundle`.
+
+### Running generation
+For the generation we need the graphql intorspection json.
+This can be genrated on https://tools.w3cub.com/graphql-to-introspection-json.
+But the result from that website must be wrapped into `{ 'data':` at the start and `}` at the end.
+The resulting json must be saved in `schema.json`.
+
+Run `generate.sh` without any arguments
+This will delete and create the neccesarry folders and generate the code.
+
+### Manual fixing
+Due to some problems in the generator, there are some minor bugs generated.
+In some classes the class `com.shopify.graphql.support.Query` is imported but conflicts with the generated 
+`de.unistuttgart.iste.rss.ccims.eclipseplugin.apibindings.Query`. This causes syntax errors.
+In these cases just delete the import.
+
+### Using nix
+You can use `nix-shell` to perform the preparations and the generation by running:
+`nix-shell --run "bash generate.sh"`
