 # Makefiles Forever
 
 A drop-in collection of makefiles libraries for your projects
 
 ## Description
 
-* plantuml.makefile — Build [plantuml](https://plantuml.com/) diagrams
+* plantuml.makefile — Automate the building [plantuml](https://plantuml.com/) diagrams.
-* dot.mk — Build [graphviz](https://graphviz.org/) graph diagrams
+* graphviz.mk — Streamline the creation of [graphviz](https://graphviz.org/) graph diagrams.
-* mocodo.mk — Build [mocodo](http://mocodo.wingi.net/) entity-relation and logical diagrams
+* mocodo.mk — Facilitate the development of [mocodo](http://mocodo.wingi.net/) entity-relation and logical diagrams.
+* mypaint.mk - Automate the conversion of [mypaint](https://mypaint.app/) openraster images to usual image formats.
 
 ## Usage
 
-Add this repository as a GIT submodule of your project
+### Adding to your project
+
+To include 'Makefiles Forever' in your project, add this repository as a GIT
+submodule:
 
 ```shell-session
 $ git submodule add https://github.com/glenux/makefiles-forever .makefiles
 ```
 
-Include needed features in the end of your makefile
+### Configuring your makefiles
+
+In your project's makefile, include the necessary modules. __The `include` instructions must be located
+__before your existing targets__.
 
 ```makefile
-# [...]
+# [... variable definitions ...]
 
--include .makefiles/featureA.mk
+# Include as many Makefiles Forever features as your want
--include .makefiles/featureB.mk  
+include .makefiles/plantuml.mk
+include .makefiles/mocodo.mk
+include .makefiles/graphviz.mk
+
+# [... targets definitions ...]
 ```
 
 Declare API variables (ex: `*_SRC_DIR`, `*_DEST_DIR`) for each module
 
 ```makefile
-# Configuration for featureA from Makefiles Forever
+# PlantUML Configuration
-FEATUREA_SRC_DIR=/path/to/somewhere
+PLANTUML_SRC_DIR=/path/to/plantuml/files
-FEATUREA_DEST_DIR=/some/other/path
+PLANTUML_DEST_DIR=/path/to/output/directory
 
-# Configuration for featureB from Makefiles Forever
+# Mocodo Configuration
-FEATUREA_SRC_DIR=/another/path
+MOCODO_SRC_DIR=/path/to/mocodo/files
-FEATUREB_DEST_DIR=/a/different/one
+MOCODO_DEST_DIR=/path/to/output/directory
+
+# Graphviz Configuration
+GRAPHVIZ_SRC_DIR=/path/to/mocodo/files
+GRAPHVIZ_DEST_DIR=/path/to/output/directory
+
+# [ ... etc ...]
 ```
 
-Use pre-defined targets as dependencies of your targets:
+Use pre-defined targets in your build process, as dependencies of your existing
+targets:
 
 ```makefile
-build: featureA-build
-build: featureB-build
 
-clean: featureA-clean
+build: plantuml-build mocodo-build graphviz-build
-clean: featureB-clean
+
+clean: plantuml-clean mocodo-clean graphviz-clean
 ```
 
 Feature files usually define more targets than just build and clean, and you
 can use those too!
 
 
-## Good practices for coding .mk files
+## Best practices used in our .mk modules
 
-* Keep task parallelism in mind
+* Parallel Execution: We ensure targets are available from the root makefile and avoid descending into subdirectories for parallel execution.
-  * Make all targets available from root makefile 
+* Modular Design: We keep our makefiles modular for easy maintenance and scalability.
-  * Do not descend in subdirectories
+* Documentation: We comment our makefiles for clarity and ease of use by others.
+
