+## Compilation NetBSD
+
+   Requires at least GCC 10.
+
+   Note that GNU make (`gmake`) is required to compile on NetBSD.
+
+<details>
+<summary>
+
+### With gmake
+</summary>
+
+1. **Install dependencies**
+
+   ```bash
+   pkg_add gmake gcc10 coreutils git
+   ```
+
+2. **Clone repository**
+
+   ```bash
+   git clone https://github.com/aristocratos/btop.git
+   cd btop
+   ```
+
+3. **Compile**
+
+   ```bash
+   gmake CXXFLAGS="-DNDEBUG"
+   ```
+
+   Options for make:
+
+   | Flag                            | Description                                                             |
+   |---------------------------------|-------------------------------------------------------------------------|
+   | `VERBOSE=true`                  | To display full compiler/linker commands                                |
+   | `STATIC=true`                   | For static compilation (only libgcc and libstdc++)                      |
+   | `QUIET=true`                    | For less verbose output                                                 |
+   | `STRIP=true`                    | To force stripping of debug symbols (adds `-s` linker flag)             |
+   | `DEBUG=true`                    | Sets OPTFLAGS to `-O0 -g` and enables more verbose debug logging        |
+   | `ARCH=<architecture>`           | To manually set the target architecture                                 |
+   | `FORTIFY_SOURCE=false`          | Disable fortification with `_FORTIFY_SOURCE=3`                          |
+   | `ADDFLAGS=<flags>`              | For appending flags to both compiler and linker                         |
+   | `CXX=<compiler>`                | Manually set which compiler to use                                      |
+
+   Example: `gmake ADDFLAGS=-march=native` might give a performance boost if compiling only for your own system.
+
+4. **Install**
+
+   ```bash
+   sudo gmake install
+   ```
+
+   Append `PREFIX=/target/dir` to set target, default: `/usr/local`
+
+   Notice! Only use "sudo" when installing to a NON user owned directory.
+
+5. **(Recommended) Set suid bit to make btop always run as root (or other user)**
+
+   ```bash
+   sudo gmake setuid
+   ```
+
+   No need for `sudo` to see information for non user owned processes and to enable signal sending to any process.
+
+   Run after make install and use same PREFIX if any was used at install.
+
+   Set `SU_USER` and `SU_GROUP` to select user and group, default is `root` and `wheel`
+
+* **Uninstall**
+
+   ```bash
+   sudo gmake uninstall
+   ```
+
+* **Remove any object files from source dir**
+
+   ```bash
+   gmake clean
+   ```
+
+* **Remove all object files, binaries and created directories in source dir**
+
+   ```bash
+   gmake distclean
+   ```
+
+* **Show help**
+
+   ```bash
+   gmake help
+   ```

+### With CMake (Community maintained)
+</summary>
+
+1. **Install build dependencies**
+
+   Requires GCC, CMake, Ninja and Git
+
+   ```bash
+   pkg_add cmake ninja-build gcc10 coreutils git
+   ```
+
+2. **Clone the repository**
+
+   ```bash
+   git clone https://github.com/aristocratos/btop.git && cd btop
+   ```
+
+3. **Compile**
+
+   ```bash
+   # Configure
+   cmake -DCMAKE_CXX_COMPILER="/usr/pkg/gcc10/bin/g++" -B build -G Ninja
+   # Build
+   cmake --build build
+   ```
+
+   This will automatically build a release version of btop.
+
+   Some useful options to pass to the configure step:
+
+   | Configure flag                  | Description                                                             |
+   |---------------------------------|-------------------------------------------------------------------------|
+   | `-DBTOP_LTO=<ON\|OFF>`          | Enables link time optimization (ON by default)                          |
+   | `-DBTOP_USE_MOLD=<ON\|OFF>`     | Use mold to link btop (OFF by default)                                  |
+   | `-DBTOP_PEDANTIC=<ON\|OFF>`     | Compile with additional warnings (OFF by default)                       |
+   | `-DBTOP_WERROR=<ON\|OFF>`       | Compile with warnings as errors (OFF by default)                        |
+   | `-DBTOP_FORTIFY=<ON\|OFF>`      | Detect buffer overflows with `_FORTIFY_SOURCE=3` (ON by default)        |
+   | `-DCMAKE_INSTALL_PREFIX=<path>` | The installation prefix ('/usr/local' by default)                       |
+
+   To force any other compiler, run `CXX=<compiler> cmake -B build -G Ninja`
+
+4. **Install**
+
+   ```bash
+   cmake --install build
+   ```
+
+   May require root privileges
+
+5. **Uninstall**
+
+   CMake doesn't generate an uninstall target by default. To remove installed files, run
+   ```
+   cat build/install_manifest.txt | xargs rm -irv
+   ```
+
+6. **Cleanup build directory**
+
+   ```bash
+   cmake --build build -t clean
+   ```
+
