 ### Build, install and test CodeCompass
 You can use the `codecompass-build.sh` script inside the container to build,
 install and test CodeCompass:
-(If you get a timeout error when downloading, put this command before install: NODE_OPTIONS="--max-old-space-size=4096" NEXT_PRIVATE_BUILD_WORKER_TIMEOUT=600)
 ```bash
 # Build CodeCompass.

-### Make a Postgresql container
-You need to create a PostgreSQL container that CodeCompass can communicate with.
-(postgres is the image name and :15 is the specific version)
-```bash
-docker run \
-  --name postgres_container \
-  -e POSTGRES_PASSWORD=root_password \
-  -d \
-  -p 5432:5432 \
-  postgres:15
-```
-
-### Create a network and connect CodeCompass and Postgres
-Run the containers and connect them to a nework
-```bash
-docker network create my_network
-docker network connect my_network postgres_name
-docker network connect my_network codecompass_container
-```
-### Create a Postgres user
-You need to create a Postgres user and give it admin rights.
-(Run these commands from the host computer)
-```bash
-# Create user "your_user" with password "your_password" and give Superuser rights
-docker exec -it postgres_container psql -U postgres -d postgres -c "CREATE USER your_user WITH PASSWORD 'your_password' SUPERUSER;"
-```

 ### How to parse a project
 You can parse a project inside a docker container by using the following
 command:
-(The project must be built before parsing.)
 ```bash
 CodeCompass_parser \
-  -d "pgsql:database=myproject;host=codecompass-postgres;port=5432;user=your_user;password=your_password" \
+  -d "sqlite:database=/CodeCompass/workspace/myproject/data.sqlite" \
   -w /CodeCompass/workspace \
   -n myproject \
   -i /projects/myproject
-  -b /projects/myproject/projectname/bin/Debug \
-  -f
 ```
 
 *Note*: the project directory should be mounted inside the container.
 
 ### How to start a webserver
 You can start a webserver inside the container by using the following command:
 ```bash
+# Create a workspace directory.
+mkdir -p /CodeCompass/workspace
+
 # Run the web server.
 CodeCompass_webserver \
   -w /CodeCompass/workspace
