described in docs/agent-guide and the approved implementation plan.

+## Description
+
+This library parses a file graph directory and returns it as a datascript
+database connection. This library mainly exists to convert file graphs to DB graphs.
+This library is compatible with ClojureScript and with
+[nbb-logseq](https://github.com/logseq/nbb-logseq) to respectively provide
+frontend and commandline functionality.
+
+## API
+
+This library is under the parent namespace `logseq.graph-parser`. This library
+provides two main namespaces, `logseq.graph-parser.exporter` and
+`logseq.graph-parser.extract`.
+
+## Usage
+
+See [nbb-logseq example
+scripts](https://github.com/logseq/nbb-logseq/tree/main/examples) for example
+usage.
+
+## Dev
+
+This follows the practices that [the Logseq frontend
+follows](/docs/dev-practices.md). Most of the same linters are used, with
+configurations that are specific to this library. See [this library's CI
+file](/.github/workflows/deps-graph-parser.yml) for linting examples.
+
+### Setup
+
+To run linters and tests, you'll want to install pnpm dependencies once:
+```
+pnpm install
+```
+
+This step is not needed if you're just running the frontend application.
+
+### Testing
+
+Testing is done with nbb-logseq and
+[nbb-test-runner](https://github.com/nextjournal/nbb-test-runner). Some basic usage:
+
+```
+# Run all tests
+$ pnpm test
+# List available options
+$ pnpm test -H
+# Run tests with :focus metadata flag
+$ pnpm test -i focus
+```
+
+### Managing dependencies
+
+The package.json dependencies are just for testing and should be updated if there is
+new behavior to test.
+
+The deps.edn dependencies are used by both ClojureScript and nbb-logseq. Their
+versions should be backwards compatible with each other with priority given to
+the frontend. _No new dependency_ should be introduced to this library without
+an understanding of the tradeoffs of adding this to nbb-logseq.
