 Kùzu is being actively developed at University of Waterloo as a feature-rich and usable GDBMS. Kùzu is available under a permissible license. So try it out and help us make it better! We welcome your feedback and feature requests.
 
-## Build
-To build from source code, Kùzu requires Cmake(>=3.11), Python 3, and a compiler that supports `C++20`.
-- Perform a full clean build without tests and benchmark:
-  - `make clean && make release`
-- Perform a full clean build with tests and benchmark (optional):
-  - `make clean && make all`
-- Run tests (optional):
-  - `make test && make pytest`
-
-For development, use `make debug` to build a non-optimized debug version.
-To build in parallel, pass `NUM_THREADS` as parameter, e.g., `make NUM_THREADS=8`.
-
-After build, our CLI binary `kuzu_shell` is available under the directory `build/release/tools/shell/`.

-## Example
+## Getting Started
 We take `tinysnb` as an example graph, which is under `dataset/demo-db/csv` in our source code, and can be downloaded [here](https://github.com/kuzudb/kuzu/tree/master/dataset/demo-db/csv).
 
 ### CLI
-#### Start CLI
-```
-./build/release/tools/shell/kuzu_shell "./testdb"
-```
-#### Schema Definition
+
+Start CLI with a database directory `./kuzu_shell ./testdb/`
 ```cypher
+# Data definition
 kuzu> CREATE NODE TABLE User(name STRING, age INT64, PRIMARY KEY (name));
 kuzu> CREATE REL TABLE Follows(FROM User TO User, since INT64);
-```
-
-#### Data Import
-```cypher
+# Data loading
 kuzu> COPY User FROM "dataset/demo-db/csv/user.csv";
 kuzu> COPY Follows FROM "dataset/demo-db/csv/follows.csv";
-```
-
-After creating node/rel tables, and importing csv files, you can now run queries!
-```cypher
+# Querying
 kuzu> MATCH (a:User)-[f:Follows]->(b:User) RETURN a.name, b.name, f.since;
 ```
