 linuxdeploy was greatly influenced by [linuxdeployqt](https://github.com/probonopd/linuxdeployqt), and while it employs stricter rules on AppDirs, it's more flexible in use. If you use linuxdeployqt at the moment, consider switching to linuxdeploy today!
 
 
-## User guides and examples
+## Usage
 
-Please see the [linuxdeploy user guide](https://docs.appimage.org/packaging-guide/from-source/linuxdeploy-user-guide.html) and the [native binaries packaging guide](https://docs.appimage.org/packaging-guide/from-source/native-binaries.html) in the [AppImage documentation](https://docs.appimage.org). There's also an [examples section](https://docs.appimage.org/packaging-guide/from-source/native-binaries.html#examples).
+linuxdeploy, being a tool for creating AppDirs and eventually AppImages, is released as an AppImage itself. Please download and use the AppImage for normal use. If you encounter errors, e.g., when building the tool from source, please try with the AppImage first before [creating an issue](https://github.com/TheAssassin/linuxdeploy/issues/new).
 
+There are two main ways to use linuxdeploy: Provide the paths to all files you want to bundle manually, or create an FHS-like directory and run linuxdeploy on it.
 
-## Projects using linuxdeploy
+Most build systems provide some kind of `make install` functionality that is capable of producing FHS-like directory trees that can be turned into AppDirs:
 
-This is an incomplete list of projects using linuxdeploy. You might want to read their build scripts to see how they use linuxdeploy.
+```sh
+# automake
+./configure --prefix=/usr
+make install DESTDIR=AppDir
 
-- [Pext](https://github.com/Pext/Pext)
-- [AppImageLauncher](https://github.com/TheAssassin/AppImageLauncher)
-- [OpenRCT2](https://github.com/OpenRCT2/OpenRCT2)
-- [AppImageUpdate](https://github.com/AppImage/AppImageUpdate)
-- [appimaged](https://github.com/AppImage/appimaged)
-- [MediaElch](https://github.com/Komet/MediaElch/)
-- [CPU-X](https://github.com/X0rg/CPU-X) (details available [here](https://github.com/AppImage/AppImageKit/wiki/Bundling-GTK3-apps#fully-automated-deployment-from-sources-with-github-actions-cpu-x))
+# cmake
+mkdir build && cd build
+cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr
+make install DESTDIR=AppDir
+
+# qmake
+qmake CONFIG+=release PREFIX=/usr .
+make install INSTALL_ROOT=AppDir
+```
+
+Now, simply run linuxdeploy like `./linuxdeploy*.AppImage --appdir AppDir`.
+
+Please use `./linuxdeploy*.AppImage --help` to get a list of options supported by linuxdeploy.
+
+If your build system cannot produce such install trees or you prefer to bundle everything manually, you can also specify the paths to the resources yourself. linuxdeploy provides the following options for this use case:
+
+```
+-l[library...],
+--lib=[library...],
+--library=[library...]            Shared library to deploy
+-e[executable...],
+--executable=[executable...]      Executable to deploy
+-d[desktop file...],
+--desktop-file=[desktop file...]  Desktop file to deploy
+                                  enough for some tests
+-i[icon file...],
+--icon-file=[icon file...]        Icon to deploy
+```
+
+An example run could look like this:
+
+```bash
+./linuxdeploy*.AppImage --app-name myapp --appdir AppDir --init-appdir -e myapp -d myapp.desktop -i myapp_64x64.png
+```
+
+Of course both approaches can be combined, e.g., you can bundle additional executables with your main app.
+
+linuxdeploy doesn't mind being run on an AppDir more than once, as it recognize previous runs, and should not break files within the AppDir. This is to allow you debug issues allows you to run linuxdeploy after resolving an issue that it reports.
+If you ever encounter issues when running linuxdeploy on an existing AppDir, please let us know by [creating an issue](https://github.com/TheAssassin/linuxdeploy/issues/new).

-# CHANGES:
-#
-# 2012-01-31, Lars Bilke
-# - Enable Code Coverage
-#
-# 2013-09-17, Joakim Söderberg
-# - Added support for Clang.
-# - Some additional usage instructions.
-#
-# 2016-02-03, Lars Bilke
-# - Refactored functions to use named parameters
-#
-# 2017-06-02, Lars Bilke
-# - Merged with modified version from github.com/ufz/ogs
-#
-#
-# USAGE:
-#
-# 1. Copy this file into your cmake modules path.
-#
-# 2. Add the following line to your CMakeLists.txt:
-#      include(CodeCoverage)
-#
-# 3. Append necessary compiler flags:
-#      APPEND_COVERAGE_COMPILER_FLAGS()
-#
-# 4. If you need to exclude additional directories from the report, specify them
-#    using the COVERAGE_LCOV_EXCLUDES variable before calling SETUP_TARGET_FOR_COVERAGE_LCOV.
-#    Example:
-#      set(COVERAGE_LCOV_EXCLUDES 'dir1/*' 'dir2/*')
-#
-# 5. Use the functions described below to create a custom make target which
-#    runs your test executable and produces a code coverage report.
-#
-# 6. Build a Debug build:
-#      cmake -DCMAKE_BUILD_TYPE=Debug ..
-#      make
-#      make my_coverage_target
-#
