+## Build
+
+In order to generate the files `qcms.js` and `qcms_bg.wasm`:
+* git clone https://github.com/mozilla/pdf.js.qcms/
+* the build requires to have a [Docker](https://www.docker.com/) setup and then:
+  * `node build.js -C` to build the Docker image
+  * `node build.js -co /pdf.js/external/qcms/` to compile the decoder
+
+## Licensing
+
+[qcms](https://github.com/FirefoxGraphics/qcms) is under [MIT](https://github.com/FirefoxGraphics/qcms/blob/main/COPYING)
+and [pdf.js.qcms](https://github.com/mozilla/pdf.js.qcms/) is released under [MIT](https://github.com/mozilla/pdf.js.qcms/blob/main/LICENSE) license so `qcms.js` and `qcms_bg.wasm` are released under [MIT](https://github.com/mozilla/pdf.js.qcms/blob/main/LICENSE) license too.
