+ * Linux: Added support for paravirtualized disks.
+
+# 0.17.5
+
+ * Improved network code: network interfaces were handled a bit differently depending on the platform, it is now unified.
+
+# 0.17.4
+
+ * Linux: fixed invalid network interface cleanup when an interface was removed from the system in `refresh_networks_list`.
+ * Added freebsd to CI runs.

+ * Linux: fixed `System::refresh_process` return value.
+
+# 0.17.1
+

+ * Linux: fixed process name retrieval by using `stat` information instead.
+ * Apple: only list local users.
+
+# 0.17.0
+
+ * Linux: fixed OS version retrieval by adding a fallback to `/etc/lsb-release`.
+ * iOS: fixed warnings.
+ * Renamed `ProcessStatus::to_string` method to `as_str`.
+ * macOS: fixed CPU usage computation.
+
+# 0.16.5
+
+ * Windows: Removed trailing NUL bytes in hostname.

+
+# 0.16.3
+
+ * Updated minimum libc version to 0.2.86.
+
+# 0.16.2
+
+ * Fixed network values computation: replaced the simple arithmetic with `saturating_sub` and `saturating_add`.
+ * Converted values read in `/proc/meminfo` from KiB to KB (because contrary to what is said in the manual, they are in KiB, not in KB).
+ * macOS: Rewrote `get_disks` function to remove the Objective-C dependency.
+ * Added `SystemExt::get_long_os_version`.
+ * Linux: Fixed sequences for disks.
+ * Linux: Allowed `/run/media` as a mount path.
+ * Windows: Fixed disk size computation.

+# sysinfo ![img_github_ci] [![][img_crates]][crates] [![][img_doc]][doc]
+
+`sysinfo` is a crate used to get a system's information.
+
+## Supported Oses
+
+It currently supports the following OSes (alphabetically sorted):
+
+ * Android
+ * FreeBSD
+ * iOS
+ * Linux
+ * macOS
+ * Raspberry Pi
+ * Windows
+
+You can still use `sysinfo` on non-supported OSes, it'll simply do nothing and always return
+empty values. You can check in your program directly if an OS is supported by checking the
+[`SystemExt::IS_SUPPORTED`] constant.
+
+The minimum-supported version of `rustc` is **1.54**.
+
+## Usage
+
+⚠️ Before any attempt to read the different structs' information, you need to update them to
+get up-to-date information because for most of them, it works on diff between the current value
+and the old one.
+
+Which is why, it's much better to keep the same instance of [`System`] around instead of
+recreating it multiple times.
+
+You have an example into the `examples` folder. You can run it with `cargo run --example simple`.
+
+Otherwise, here is a little code sample:
+
+```rust
+use sysinfo::{NetworkExt, NetworksExt, ProcessExt, System, SystemExt};
+
+// Please note that we use "new_all" to ensure that all list of
+// components, network interfaces, disks and users are already
+// filled!
+let mut sys = System::new_all();
+
+// First we update all information of our `System` struct.
+sys.refresh_all();
+
+// We display all disks' information:
+println!("=> disks:");
+for disk in sys.disks() {
+    println!("{:?}", disk);
+}
+
+// Network interfaces name, data received and data transmitted:
+println!("=> networks:");
+for (interface_name, data) in sys.networks() {
+    println!("{}: {}/{} B", interface_name, data.received(), data.transmitted());
+}
+
+// Components temperature:
+println!("=> components:");
+for component in sys.components() {
+    println!("{:?}", component);
+}
+
+println!("=> system:");
+// RAM and swap information:
+println!("total memory: {} KB", sys.total_memory());
+println!("used memory : {} KB", sys.used_memory());
+println!("total swap  : {} KB", sys.total_swap());
+println!("used swap   : {} KB", sys.used_swap());
+
+// Display system information:
+println!("System name:             {:?}", sys.name());
+println!("System kernel version:   {:?}", sys.kernel_version());
+println!("System OS version:       {:?}", sys.os_version());
+println!("System host name:        {:?}", sys.host_name());
+
+// Number of CPUs:
+println!("NB CPUs: {}", sys.cpus().len());
+
+// Display processes ID, name na disk usage:
+for (pid, process) in sys.processes() {
+    println!("[{}] {} {:?}", pid, process.name(), process.disk_usage());
+}
+
+```
+
+By default, `sysinfo` uses multiple threads. However, this can increase the memory usage on some
+platforms (macOS for example). The behavior can be disabled by setting `default-features = false`
+in `Cargo.toml` (which disables the `multithread` cargo feature).
+
+### Running on Raspberry Pi
+
+It'll be difficult to build on Raspberry Pi. A good way-around is to cross-build, then send the
+executable to your Raspberry Pi.
+
+First install the arm toolchain, for example on Ubuntu:
+
+```bash
+> sudo apt-get install gcc-multilib-arm-linux-gnueabihf
+```
+
+Then configure cargo to use the corresponding toolchain:
+
+```bash
+cat << EOF > ~/.cargo/config
+[target.armv7-unknown-linux-gnueabihf]
+linker = "arm-linux-gnueabihf-gcc"
+EOF
+```
+
+Finally, cross compile:
+
+```bash
+rustup target add armv7-unknown-linux-gnueabihf
+cargo build --target=armv7-unknown-linux-gnueabihf
+```
+
+### Linux on Docker & Windows Subsystem for Linux (WSL)
+
+Virtual Linux systems, such as those run through Docker and Windows Subsystem for Linux (WSL), do
+not receive host hardware information via `/sys/class/hwmon` or `/sys/class/thermal`. As such,
+querying for components may return no results (or unexpected results) when using this library on
+virtual systems.
+
+### Use in binaries running inside the macOS or iOS Sandbox/stores
+
+Apple has restrictions as to which APIs can be linked into binaries that are distributed through the app store.
+By default, `sysinfo` is not compatible with these restrictions. You can use the `apple-app-store`
+feature flag to disable the Apple prohibited features. This also enables the `apple-sandbox` feature. 
+In the case of applications using the sandbox outside of the app store, the `apple-sandbox` feature 
+can be used alone to avoid causing policy violations at runtime.
+
+### How it works
+
+I wrote a blog post you can find [here][sysinfo-blog] which explains how `sysinfo` extracts information
+on the diffent systems.
+
+[sysinfo-blog]: https://blog.guillaume-gomez.fr/articles/2021-09-06+sysinfo%3A+how+to+extract+systems%27+information
+
+### C interface
+
+It's possible to use this crate directly from C. Take a look at the `Makefile` and at the
+`examples/simple.c` file.
+
+To build the C example, just run:
+
+```bash
+> make
+> ./simple
+# If needed:
+> LD_LIBRARY_PATH=target/release/ ./simple
+```
+
+### Benchmarks
+
+You can run the benchmarks locally with rust **nightly** by doing:
+
+```bash
+> cargo bench
+```
