+# Developer advice
+
+## Ignore submodules to make git operations faster
+Antares_Simulator is quite a large project, with a few large submodules. In file .git/config, you can add this line to all [submodule] sections
+
+```
+ignore = all
+```
+
+This way git won't waste time computing diff on these when checking out, diffing commits, etc. git operations should be a lot faster. Keep in mind that your submodules won't be updated.
+
+## Disable the UI build to make builds faster
+The UI takes up a good chunk of compilation time. It is enabled by default, byt you can disable it by providing CMake with this option at configure time
+
+```
+cmake -S src [...] -DBUILD_UI=OFF
+```
+
+## Use Ninja to speed up target generation by CMake
+At configure time, you may specify Ninja for generation instead of traditional Make. This will speed up the update step after you made small changes to the code.
+
+```
+cmake -S src [...] -G Ninja
+```
+
+Note that you may need to install Ninja first (package `ninja-build` on Ubuntu).
+
+## Adding the solver build path to your PATH
+If you use `antares-x.y-solver` often, you may find it convenient to add it's location to your PATH. In your .bashrc, add (with slight variations)
+
+```
+export PATH="$PATH:path/to/Antares_Simulator/build/solver
+```
+
+Then you can open a terminal and execute antares-x.y-solver by just typing
+
+```
+antares-x.y-solver
+```
