+Sqliteviz is a single-page offline-first PWA for fully client-side visualisation
+of SQLite databases, CSV, JSON or NDJSON files.
 
 With sqliteviz you can:
+
 - run SQL queries against a SQLite database and create [Plotly][11] charts and pivot tables based on the result sets
-- import a CSV file into a SQLite database and visualize imported data
+- import a CSV/JSON/NDJSON file into a SQLite database and visualize imported data
 - export result set to CSV file
 - manage inquiries and run them against different databases
 - import/export inquiries from/to a JSON file

 ## Quickstart
+
 The latest release of sqliteviz is deployed on [sqliteviz.com/app][6].
 
 ## Wiki
+
 For user documentation, check out sqliteviz [documentation][7].
 
 ## Motivation
+
 It's a kind of middleground between [Plotly Falcon][1] and [Redash][2].
 
 ## Components
+
 It is built on top of [react-chart-editor][3], [PivotTable.js][12], [sql.js][4] and [Vue-Codemirror][8] in [Vue.js][5]. CSV parsing is performed with [Papa Parse][9].

+This directory contains a micro-benchmark for evaluating SQLite WebAssembly
+builds performance on read and write SQL queries, run from `make.sh` script. If
+the script has permission to `nice` processes and [Procpath][1] is installed,
+e.g. it is run with `sudo -E env PATH=$PATH ./make.sh`, it'll `renice` all
+processes running inside the benchmark containers. It can also serve as a smoke
+test (e.g. for memory leaks).
 
-The benchmark operates on a set of SQLite WebAssembly builds expected
-in `lib/build-$NAME` directories each containing `sql-wasm.js` and
-`sql-wasm.wasm`. Then it creates a Docker image for each, and runs
-the benchmark in Firefox and Chromium using Karma in the container.

-After successful run, the benchmark result of each build is contained
-in `build-$NAME-result.json`. The JSON result files can be analysed
-using `result-analysis.ipynb` Jupyter notebook.
+After successful run, the benchmark produces the following per each build:
+
+- `build-$NAME-result.json`
+- `build-$NAME.sqlite` (if Procpath is installed)
+- `build-$NAME.svg` (if Procpath is installed)
+
+These files can be analysed using `result-analysis.ipynb` Jupyter notebook.
+The SVG is a chart with CPU and RSS usage of each test container (i.e. Chromium
+run, then Firefox run per container).
