 ## Developing
 
-You'll want to run these two commands at the same time:
+### Generating GraphQL code
+
+Because the LLDAP GraphQL API is locked behind authentication, and of a quirk with `graphl-codegen` configuration files, we need to set a temporary environment variable to generate GraphQL code. If not using introspection, you will need a running LLDAP server.
+
+Run the `get-token.js` helper script and set the environment variable from its output:
+
+```shell
+node get-token.js
+export GRAPHQL_CODEDGEN_AUTH=...
+```
+
+Then, generate the GraphQL code:
+
+```shell
+npm run graphql-codegen
+```
+
+If you want to use introspection, set `GRAPHQL_USE_INTROSPECTION=true` before generating the code. You won't need to set the auth environment variable in this case.
+
+### Working with Prisma
+
+gluestick uses [Prisma](https://www.prisma.io/) for accessing the database. If you will be modifying the database schema, you will need to work with it. Consider taking some time to familiarize yourself with the [Prisma CLI](https://www.prisma.io/docs/reference/api-reference/command-reference) first.
