+Installation
+------------
 
-Refer to the [documentation](http://minijson.readthedocs.io/en/latest/?badge=latest)
-for use.
+You should be able to install it from our own PyPI:
 
+```bash
+pip install --extra-index-url https://git.dms-serwis.com.pl/api/v4/projects/284/packages/pypi/simple minijson
+```
+
+There should be plenty of binaries available for multiple platforms. If you'd
+like a new one, just file an issue
 If there are no binary wheels precompiled for this platform, you will need to
 compile it yourself.
 Alternatively, you can
-[file an issue](https://github.com/smok-serwis/minijson/issues/new)
+[file an issue](https://git.dms-serwis.com.pl/smokserwis/minijson/-/issues)
 and I'll do my best to compile a wheel for you.
