+# How to Contribute to LibAFL
+
+For bugs, feel free to open issues or contact us directly. Thank you for your support. <3
+
+## Pull Request guideline
+
+Even though we will gladly assist you in finishing up your PR, try to
+- keep all the crates compiling with *stable* rust (hide the eventual non-stable code under [`cfg`s](https://github.com/AFLplusplus/LibAFL/blob/main/libafl/build.rs#L26))
+- run `cargo +nightly fmt` on your code before pushing
+- check the output of `cargo clippy --all` or `./clippy.sh`
+- run `cargo build --no-default-features` to check for `no_std` compatibility (and possibly add `#[cfg(feature = "std")]`) to hide parts of your code.
+
+Some of the parts in this list may be hard, don't be afraid to open a PR if you cannot fix them by yourself, so we can help.
+
+### Pre-commit hooks
+
+Some of these checks can be performed automatically during commit using [pre-commit](https://pre-commit.com/).
+Once the package is installed, simply run `pre-commit install` to enable the hooks, the checks will run automatically before the commit becomes effective.

+# General debugging tips
+This file answers some commmon questions that arise when you are writing a fuzzer using LibAFL.
+
+## Q. My fuzzer crashed but the stack trace is useless.
+You can enable the `errors_backtrace` feature of the `libafl` crate. With this the stacktrace is meaningful.
+
+## Q. I started the fuzzer but the corpus count is 0.
+Unless the initial corpus is loaded with the "load_initial_inputs_forced" function, we only store the interesting inputs, which is the inputs that triggered the feedback. So this usually means that your input was not interesting or your target was simply not properly implemented. 
+Either way, what you can do is attach to the executable with gdb and set a breakpoint at where the new edges should be reported. If no instrumentation code is executed, then the the problem is in the instrumentation. If the instrumentation code is hit, but still the your input is not instrumented, then the problem could be that you are not passign the observer/feedback correctly to the fuzzer.
+
+## Q. I started the fuzzer but the coverage is 0.
+This could mean two things. Perhaps your target was not properly instrumented, or you are not using the correct observer, feedback feature.
+In this case, again, what usually should do is to run the fuzzer with gdb and set a breakpoint at where the coverage is recorded (e.g. __sanitizer_coverage_trace_pcguard), and validate that the target is giving the feedback to the fuzzer.
+
+## Q. I started the fuzzer but there's no output.
+First, verify that your stdout and stderr are not redirected to `/dev/null`. If you get the log, then it should either fall into the previous 2 cases. Either the fuzzer crashed because you didn't have the initial seeds, or the coverage feedback is not working.
+
+## Q. My fuzzer is slow.
+Try running the fuzzer with the `introspection` feature of the `libafl`. This will show how much time is spent on each module of your fuzzer. Also you might be using a wrong size of the coverage map. If you see `2621440` for the size of the coverage map, you are doing it wrong. One possible mistake is the misuse of `libafl_targets::coverage::EDGES_MAP`
+```
+let map = StdMapObserver::from_mut_ptr("edges", EDGES_MAP.as_mut_ptr(), EDGES_MAP.len());
+```
+You should *never* use the `EDGES_MAP`'s size as this is just the size of the allocated size of the coverage map. Consider using something smaller or our default value `libafl_targets::LIBAFL_EDGES_MAP_SIZE_IN_USE`.
+
+## Q. I still have problems with my fuzzer.
+Finally, if you really have no idea what is going on, run your fuzzer with logging enabled. (You can use `env_logger`, `SimpleStdoutLogger`, `SimpleStderrLogger` from `libafl_bolts`. `fuzzbench_text` has an example to show how to use it.) (Don't forget to enable stdout and stderr), and you can open an issue or ask us in Discord.
+
+## Q. My fuzzer died of ``Storing state in crashed fuzzer instance did not work''.
+If the exit code is zero, then this is because either your harness exited or you are using fuzzer_loop_for and forgot to add `mgr.on_restart` at the end of the fuzzer. In the first case, you should patch your harness not to exit. (or use `utils/deexit`).
+
+## Q. I can't leave the TUI screen
+Type `q` then you leave TUI.

 ### Building the Fuzzer
 
 No matter the instrumentation method, the interface between the fuzzer and the instrumented target should now be consistent.
 The only difference between using SymCC and SymQEMU should be the binary that represents the target:
-In the case of SymCC it will be the binary that was build with instrumentation and with SymQEMU it will be the emulator binary (eg. `x86_64-linux-user/symqemu-x86_64`), followed by your uninstrumented target binary and arguments.

 #### Serialization and Solving
 
 While it is perfectly possible to build a custom runtime that also performs the solving step of hybrid fuzzing in the context of the target process, the intended use of the LibAFL concolic tracing support is to serialize the (filtered and pre-processed) branch conditions using the [`TracingRuntime`](https://docs.rs/symcc_runtime/0.1/symcc_runtime/tracing/struct.TracingRuntime.html).
-This serialized representation can be deserialized in the fuzzer process for solving using a [`ConcolicObserver`](https://docs.rs/libafl/0.6.0/libafl/observers/concolic/struct.ConcolicObserver.html) wrapped in a [`ConcolicTracingStage`](https://docs.rs/libafl/0.6.0/libafl/stages/concolic/struct.ConcolicTracingStage.html), which will attach a [`ConcolicMetadata`](https://docs.rs/libafl/0.6.0/libafl/observers/concolic/struct.ConcolicMetadata.html) to every [`TestCase`](https://docs.rs/libafl/0.6.0/libafl/corpus/testcase/struct.Testcase.html).

 Another required component is the **EventManager**. It handles some events such as the addition of a testcase to the corpus during the fuzzing process. For our purpose, we use the simplest one that just displays the information about these events to the user using a `Monitor` instance.

+For this, imports for types in LibAFL bolts have changed in version 0.11, everything else should remain the same.
+
+## Reasons for This Change
+
+With the change we can now use a lot of low-level features of LibAFL for projects that are unrelated to fuzzing, or just completely different to LibAFL.
+Some cross-platform things in bolts include
+
+* SerdeAnyMap: a map that stores and retrieves elements by type and is serializable and deserializable
+* ShMem: A cross-platform (Windows, Linux, Android, MacOS) shared memory implementation
+* LLMP: A fast, lock-free IPC mechanism via SharedMap
+* Core_affinity: A maintained version of `core_affinity` that can be used to get core information and bind processes to cores
+* Rands: Fast random number generators for fuzzing (like [RomuRand](http://www.romu-random.org/))
+* MiniBSOD: get and print information about the current process state including important registers.
+* Tuples: Haskel-like compile-time tuple lists
+* Os: OS specific stuff like signal handling, windows exception handling, pipes, and helpers for `fork`
+
+## What changed
+
+You will need to move all `libafl::bolts::` imports to `libafl_bolts:::` and add the crate dependency in your Cargo.toml (and specify feature flags there).
+As only exception, the `libafl::bolts::launcher::Launcher` has moved to `libafl::events::launcher::Launcher` since it has fuzzer and `EventManager` specific code.
+If you are using `prelude`, you may need to also ad `libafl_bolts::prelude`.

-cd example; sh build.sh; cd ..
-```
-
-This will build the the fuzzer (src/fuzzer.rs) and a small example binary based on FreeRTOS, which can run under a qemu emulation target.

-## Run
-
-Since the instrumentation is based on snapshtos QEMU needs a virtual drive (even if it is unused...).
-Create on and then run the fuzzer:
-```bash
-# create an image
-qemu-img create -f qcow2 dummy.qcow2 32M
-# run the fuzzer
-KERNEL=./example/example.elf target/release/qemu_systemmode -icount shift=auto,align=off,sleep=off -machine mps2-an385 -monitor null -kernel ./example/example.elf -serial null -nographic -snapshot -drive if=none,format=qcow2,file=dummy.qcow2 -S
-```
-Currently the ``KERNEL`` variable is needed because the fuzzer does not parse QEMUs arguments to find the binary.
