+Thanks for your interest in contributing to cpufetch! Please, read this page carefully to understand how to contribute to cpufetch.
+
+## 1. cpufetch does not accept pull requests
+cpufetch is a small project, and I enjoy developing it. There are for sure some bugs and exciting features to add, but I prefer to make these
+changes myself. For that reason, you should always use the issues page to report anything related to cpufetch. In the rare case that there is
+a concise bug or feature that I am unable to implement myself, I will enable pull requests for this.
+
+## 2. Creating an issue
+
+### 2.1: I found a bug in cpufetch (the program provides incorrect / invalid information)
+In the github issue **you must include**:
+- Exact CPU model.
+- Operating system.
+- The output of `cpufetch`.
+- The output of `cpufetch --debug`.
+
+### 2.2: I found a bug in cpufetch (the program crashes / does not work properly)
+- Exact CPU model.
+- Operating system.
+- The output of `cpufetch`.
+- The output of `cpufetch --debug`.
+- A stacktrace (if program crashes):
+
+#### Stacktrace option 1 (best)
+1. Build cpufetch with debug symbols (`make clean; make debug`).
+2. Install valgrind (if it is not already installed)
+3. Run cpufetch with valgrind (`valgrind ./cpufetch`)
+4. Paste the complete output (preferably on a platform like pastebin)
+
+#### Stacktrace option 2 (use this option if option 1 does not work)
+1. Build cpufetch with debug symbols (`make clean; make debug`).
+2. Install gdb (if it is not already installed)
+3. Debug cpufetch with gdb (`gdb cpufetch`)
+3. Run cpufetch (just r inside gdb console)
+4. Paste the complete output (preferably on a platform like pastebin)
+
+### 2.3: I have an idea for a new feature in cpufetch / I want to suggest a change in cpufetch
+Just explain the feature in the issue and include references (links) to relevant sources if appropriate.

-You need to build `cpufetch` from source (see below).
+# 2. Installation
+## 2.1 Installing from a package
+Choose the right package for your operating system:

+
+## 2.2 Building from source (Linux/Windows/macOS)
+Just clone the repo and use `make` to compile it

-#### Android
-I recommend using `termux` terminal emulator. Once you installed it, run the following commands:
+The Makefile is designed to work on Linux, Windows and macOS.

+![cpu5](pictures/snapdragon.png)
+
+# 4. Colors and style
 By default, `cpufetch` will print the CPU art with the system colorscheme. However, you can always set a custom color scheme, either
 specifying Intel or AMD, or specifying the colors in RGB format:
 
 ```
 ./cpufetch --color intel (default color for Intel)
-./cpufetch --color amd (default color for AND)
+./cpufetch --color amd (default color for AMD)
 ./cpufetch --color 239,90,45:210,200,200:100,200,45:0,200,200 (example)
 ```
 
 In the case of setting the colors using RGB, 4 colors must be given in with the format: ``[R,G,B:R,G,B:R,G,B:R,G,B]``. These colors correspond to CPU art color (2 colors) and for the text colors (following 2). Thus, you can customize all the colors.
 
-### Implementation
+# 5. Implementation
+See [cpufetch programming documentation](https://github.com/Dr-Noob/cpufetch/doc/README.md).
 
-`cpufetch` fetches all of the information using the `CPUID` x86 instruction. There are, however, some cases where the CPU does not support fetching some needed information. In this case, `cpufetch` will use `/sys/devices/system/cpu` in Linux as a fallback. If `cpufetch` is running on Windows and `CPUID` does not give all the data, `cpufetch` won't be able to show it. [I hope this can be fixed in the future](https://github.com/Dr-Noob/cpufetch/issues/30)
+# 6. Bugs or improvements
+See [cpufetch contributing guidelines](https://github.com/Dr-Noob/cpufetch/CONTRIBUTING.md)
 
-### Bugs or improvements
-There are many open issues in github (see [issues](https://github.com/Dr-Noob/cpufetch/issues)). Feel free to open a new one report a issue or propose any improvement in `cpufetch`

+CPUID instructions (present in x86 architectures) [[1](#references)] allow user level applications to obtain information about the CPU. In ARM architectures, there are many registers (MIDR [[2](#references)], CCSIDR [[3](#references)]) that provide information about the CPU too. However, those registers can only be read from privilege mode (PL1 or higher). Therefore, any user level tool which can actually read information about the running CPU must use the operating system to do so. cpufetch uses some Linux kernel features (see the remaining sections). Therefore, cpufetch in ARM processors is limited to Linux kernel based systems, such as __GNU/Linux__ and __Android__
+
+### 3. How to get CPU microarchitecture?
+__Involved code: [get_midr_from_cpuinfo (udev.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/udev.c), [midr.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/midr.c)__
+
+Microarchitecture information is acquired from the Main ID Register (MIDR) [[2](#references)]. Currently, cpufetch rebuilds this register using `/proc/cpuinfo` file. While this file does not contain the value of the register per se, it contains the following fields:
+- `CPU implementer`,
+- `CPU architecture`
+- `CPU variant`
+- `CPU part`
+- `CPU revision`
+
+The MIDR register can be built with this information. Another posible approach is to read MIDR directly from `/sys/devices/system/cpu/cpu*/regs/identification/midr_el1`
+
+With the MIDR available, the approach is the same as the one used in x86_64 architectures. cpufetch has a file that acts like a database that tries to match the MIDR register with the specific CPU microarchitecture.
+
+### 4. How to get CPU topology?
+__Involved code: [get_ncores_from_cpuinfo (udev.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/udev.c), [midr.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/midr.c)__
+
+ARM provides a new interesting architecture feature: big.LITTLE architectures [[4](#references)]. An ARM CPU can be organized like a typical x86_64 CPU, where all cores share the same microarchitecture. However, ARM big.LITTLE architecture breaks this schema. In a big.LITTLE CPU, two or more CPUs microarchitecture live in the same chip.
+
+This means that cpufetch can't just read which microarchitecture is the first core and assume that the rest of them shares the same microarchitecture. To get the CPU topology, cpufetch first reads the number of CPU cores. This can be obtained from `/sys/devices/system/cpu/present`
+
+Then, for each core, cpufetch reads the MIDR and also the frequency (see section 5). Then, cpufetch assumes that two cores are different when their MIDR are different. This idea allows cpufetch to detect big.LITTLE architectures, and to know how many cores of each architecture the running CPU has.
+
+### 5. How to get the frequency?
+Frequency is read directly from `/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq`
+
+### 6. How to get system on chip model?
+__Involved code: [soc.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/soc.c)__
+
+System on chip (SoC) model is obtained using the same idea as the microarchitecture. First, SoC string is read. Then, the string has to be matched against a database-like function (__parse_soc_from_string__). The SoC string of the running CPU can be obtained using two different approaches:
+
+- Using `/proc/cpuinfo`. This is the first thing to try. Linux kernel usually provides the string under the `Hardware` keyword. However, the Linux kernel may be unable to provide this information, or this string may not be found in the database-like function.
+- Using Android properties: This only works on Android systems. Android properties can be read using `__system_property_get` function. cpufetch tries to read two properties:
+  - `ro.mediatek.platform`
+  - `ro.product.board`
+
+  If any string is returned, cpufetch tries to find a match in the database (using the same database as in the case of `/proc/cpuinfo`).
+
+The expected strings have to be hardcoded. I found two ways of knowing which string should correspond to which SoC:
+
+  - Searching on the internet. Manufacturers __usually__ provide this information. For example, Qualcomm usually publishes the chip name along with other characteristics (under the `Part` or `Part number` keyword [[6](#references)]).
+  - "Hunting" for the strings. For example, finding smartphones with a given SoC and manually reading the `/proc/cpuinfo` or the `build.prop` file. A very good resource to do this is the SpecDevice webpage [[7](#references)]).
+
+### 7. How to get cache size and topology?
+ARM architecture supports reading the cache information via some registers (for example, the CCSIDR register  [[3](#references)]). As mentioned earlier, user level applications are not able to read these registers directly. The remaining option is to ask the operating system for this information. However, at the moment, the __Linux kernel does not provide cache information__. Therefore, cpufetch does not print any cache information on ARM CPUs at the moment. There are, however, other approaches to be explored:
+
+- Read the registers in kernel mode. This can be accomplished by running a kernel module [[4](#references)]. Unfortunately, running a custom kernel module is tricky, and sometimes impossible to do reasonably (for example, in Android devices). In any case, my decision is to run cpufetch on user level only.
+- Hardcode the cache information for each SoC: Sometimes, manufacturers publish technical information about the chips, where cache topology and size are shown. This method is impractical, since this kind of information is very hard (or impossible) to find online, and the number of SoC is huge.
