+In the github repo of the package there is also some software that serves the sole purpose of helping with the translation of rules from Mathematica syntax, and not for the actual package working. The important ones are:
+- translator_of_rules.jl is a script that with regex and other string manipulations translates from Mathematica syntax to julia syntax (see "houw to use it" section later)
 - translator_of_testset.jl is a script that translates the testsets into julia syntax (much simpler than translator_of_rules.jl)
 - `reload_rules` function in rules_loader.jl. When developing the package using Revise is not enough because rules are defined with a macro. So this function reloads rules from a specific .jl file or from all files if called without arguments.

 ### How to use it
-It's handy to have the Mathematica files already in the correct folders in this repo (.m files are ignored by .gitignore), so that you can use the translator script like this:
+In the branch `rules` of the github repo of the package there are all the Mathematica files containing the untranslated rules already in the correct folders in this repo, so that you can use the translator script like this:

 ## Adding Testsuites
-There is a test suite of 27585 solved integrals taken from the RUBI package, in the folders `test/test_files/0 Independent test suites` (1796 tests) and `test/test_files/1 Algebraic functions` (25798 tests). But more test can be translated from the [RUBI testsuite](https://rulebasedintegration.org/testProblems.html). In [this](https://github.com/Bumblebee00/SymbolicIntegration.jl?tab=readme-ov-file#testing) repo there are the tests still in Mathematica syntax and a script to translate them to julia.
