+### Loading and Downloading Benchmark Datasets
+
 `RelationalDatasets.jl` exports a single function: `load` to return train
 and test folds.
 
 ```julia
 using RelationalDatasets
 
 train, test = load("webkb", "v0.0.4", fold=2)
-
-println(length(train.facts))
+length(train.facts)
 # 1344
 ```
 
+### Converting Vector-based Datasets
+
+*Binary classification when `y` is a vector of 0/1*:
+
+```julia
+using RelationalDatasets
+
+data, modes = RelationalDatasets.from_vector(
+  [0 1 1; 1 0 2; 2 2 0],
+  [0, 0, 1],
+)
+```
+
+*Regression when `y` is a vector of floats*:
+
+```julia
+using RelationalDatasets
+
+data, modes = RelationalDatasets.from_vector(
+  [0 1 1; 1 0 2; 2 2 0],
+  [1.1, 0.9, 2.5],
+)
+```
