+This folder contains the input file (``tox.in.h``) that has to be used to generate the ``tox.h`` api with: https://github.com/iphydf/apidsl
 
-You can also use the following command if you can't install it:
+# Minimal requirements
 
+There are some minimal requirements to contribute to ``tox.h``:
+* unix enrironment
+* ``astyle`` ``>=2.03``
+* [``apidsl``](https://github.com/iphydf/apidsl) (you can use provided service with curl instead)
+
+## Quick way
+
+If you want to do it quickly and you don't have time for anything other than copypasting commands, you should have ``curl`` installed.
+
+
+1. Make sure that you have ``curl`` and ``>=astyle-2.03`` installed
+2. Modify [``tox.in.h``](/other/apidsl/tox.in.h)
+3. Run command below ↓
+
+Command to run from ``toxcore`` directory (quick way, involves using curl):
+```bash
+rm toxcore/tox.h && \
+( curl -X POST --data-binary @- https://criticism.herokuapp.com/apidsl < ./other/apidsl/tox.in.h > ./toxcore/tox.h ) && \
+astyle --options=./other/astyle/astylerc ./toxcore/tox.h
+```
+
+When formatting will be complete, you should see output like:
 ```
-curl -X POST --data-binary @- https://criticism.herokuapp.com/apidsl < tox.in.h > tox.h
+Formatted  ./toxcore/tox.h
+```
+
+You may want to make sure with ``git diff`` that changes made in ``tox.h`` reflect changes in ``tox.in.h``.
+
+And you're done.
+
+
+## Manually
+
+If you prefer to have more control over what is happening, there are steps below:
+
+1. Install [``apidsl``](https://github.com/iphydf/apidsl)
+2. Install ``astyle``, version 2.03 or later.
+3. Modify [``tox.in.h``](/other/apidsl/tox.in.h)
+4. Use ``apidsl`` ``??``
+5. Parse generated ``tox.h`` with astyle, minimal command for it would be:
+```bash
+astyle --options=./other/astyle/astylerc ./toxcore/tox.h
 ```
 
-Note that the output must be passed through astyle with the config in 
-other/astyle/astylerc to generate the exact same file.
+**Always pass output from ``apidsl`` through astyle.**
