 ## Development setup
 
-As a requirement, please make sure to have `docker` and `docker-compose` installed as well as a set of client credentials for AzureAD.
+As a requirement, please make sure to have `docker` and `docker-compose` installed.
 
-Create a file called `.env` on the root of the repository and paste your client credentials:
+You need to have a registered Github OAuth application to use for logging in.
+To register a Github OAuth application:
+1) Go to https://github.com/settings/applications/new. The application name and homepage URL do not matter, but the Authorization callback URL must be `http://localhost:4433/self-service/methods/oidc/callback/github`.
+2) Generate a client secret
+3) Create a file called `.env` on the root of the repository and paste your client credentials:
 
-```
+```text
 CLIENT_ID=<client_id>
 CLIENT_SECRET=<client_secret>
-MICROSOFT_TENANT=<tenant_id>
 ```
 
-We are going to use docker-compose to run Kratos, Hydra and OpenFGA:
+Run the login UI's dependencies:
 
 ```console
 docker-compose -f docker-compose.dev.yml up --  build --force-recreate
 ```
 
-Now we can run the UI:
+Run the Login UI:
 ```console
 export KRATOS_PUBLIC_URL=http://localhost:4433
 export HYDRA_ADMIN_URL=http://localhost:4445
 export BASE_URL=http://localhost:4455
 export PORT=4455
 export TRACING_ENABLED=false
 export LOG_LEVEL=debug
-export OPENFGA_API_SCHEME=http

-export OPENFGA_STORE_ID=01GP1254CHWJC1MNGVB0WDG1T0
+export AUTHORIZATION_ENABLED=false
 go run cmd/main.go
 ```
+
+To test the authorizatoin code flow you can use the Ory Hydra CLI:
+
+> To install the Ory Hydra CLI follow the instruction at https://www.ory.sh/docs/hydra/self-hosted/install.
+
+```console
+code_client=$(hydra create client \
+  --endpoint http://localhost:4445 \
+  --name grafana \
+  --grant-type authorization_code,refresh_token \
+  --response-type code \
+  --format json \
+  --scope openid,offline_access,email,profile \
+  --redirect-uri http://127.0.0.1:4446/callback \
+  --audience app_client \
+)
+hydra perform authorization-code \
+  --endpoint http://localhost:4444 \
+  --client-id `echo "$code_client" | yq .client_id` \
+  --client-secret  `echo "$code_client" | yq .client_secret` \
+  --scope openid,profile,email,offline_access
