+## Description
+This is a collection of development related scripts, written as bash scripts, bb/babashka scripts and nbb scripts.
+
+## Usage
+
+### Babashka scripts
+Most bb scripts live under `src/` and are defined as bb tasks. See [babashka tasks](../docs/dev-practices.md#babashka-tasks)
+
+### Nbb scripts
+
+Before running any [nbb-logseq](https://github.com/logseq/nbb-logseq) scripts, be sure to have node >= 18.14 installed as well as a recent [babashka](https://github.com/babashka/babashka) for managing the dependencies in `nbb.edn`. Then `yarn install` to install dependencies
+
+#### Create graph scripts
+
+For database graphs, it is possible to create graphs with the
+[logseq.tasks.db-graph.create-graph](src/logseq/tasks/db_graph/create_graph.cljs)
+ns. This ns makes it easy to write scripts that create graphs by supporting a
+concise EDN map for graph generation. For example, the
+`create_graph_with_properties.cljs` script uses this ns to create a graph with
+a variety of properties:
+
+```
+$ yarn nbb-logseq src/logseq/tasks/db_graph/create_graph_with_properties.cljs ~/logseq/graphs/woot
+Generating 16 pages and 24 blocks ...
+Created graph woot!
+```
+
+This script creates a DB graph with blocks containing several property types for
+both single and many cardinality. It also includes queries for most of these
+properties. Read the docs in
+[logseq.tasks.db-graph.create-graph](src/logseq/tasks/db_graph/create_graph.cljs)
+for specifics on the EDN map.
