 ## Introduction
-Magisk is a suite of open source tools for devices running Android version higher than 5.0 Lollipop (API 21). It provides an environment which covers most Android aftermarket customization like root, boot scripts, SELinux patches, and also acts as a **Systemless Interface** to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact, all of which accomplished by only patching the boot image, and adding some files into `/data`.

+Magisk is a suite of open source tools for devices running Android version higher than 5.0 Lollipop (API 21). It establishes an environment which covers most Android aftermarket customization needs, such as root, boot scripts, SELinux patches, dm-verity/forceencrypt patches etc.. Furthermore, Magisk also provides a **Systemless Interface** to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact, all of which accomplished by only patching the boot image, and adding some files into `/data`. With its systemless nature along with several other hacks, Magisk can hide modifications from device integrity verifications, one of the main target is to hide from [Google's SafetyNet API](https://developer.android.com/training/safetynet/index.html).

-> System props are stored in a hybrid trie/binary tree data structure; it is originally designed to only support adding nodes, and no nodes will be removed. Props can be read by many processes (e.g. via the `getprop` command); however, only the `init` process can write to the data. `init` provides a `property_service` to accept property update requests, so all property changes are monitored and controlled by `init`. The restrictions of **read-only** props (props that starts with `ro.`), which they can only be set once and cannot be changed afterwards, is therefore implemented in `init`.

-**resetprop** mimics what `init` is doing: directly accessing the data structure. This bypasses the whole `property_service` part, so we gain **arbitrary modification** power. Deleting properties, which was stated *"forbidden"* in the data structure is also implemented in resetprop through some tricks.

Doing so, we gain **arbitrary modification** power, including altering read-only props and deleting properties. Delete properties, which was stated *"forbidden"* in the data structure, is implemented through some tricks in the data structure.
 
-One subtle thing to be aware of is that if we change props by directly modifying the data structure, `on property:foo=bar` triggers registered in `*.rc` scripts will not be triggered properly. This may be a good thing or a bad thing, depending on what result you want. I made the default behavior to match the original setprop command, which **will** trigger events, but still I provide a flag to disable it if you needed it.

 ### Notes
 - Sometimes, completely replacing a folder is inevitable. For example you want to replace `/system/priv-app/SystemUI` in your stock rom. In stock roms, system apps usually comes with pre-optimized files. If your replacement `SystemUI.apk` is deodexed (which is most likely the case), you would want to replace the whole `/system/priv-app/SystemUI` to make sure the folder only contains the modified `SystemUI.apk` and **NOT** merge with the pre-optimized files.
-- If you are using the [Magisk Module Template](https://github.com/topjohnwu/magisk-module-template), you can create a list of folders you want to directly replace in `config.sh`, the installation scripts will handle the creation of `.replace` files for you.
-- Adding non-existing target items is a relatively expensive operation. Magisk would need to do **MANY** under-the-hood tasks to achieve it. Replacing a whole folder is recommended if viable, it reduces the complexity of the generation of the mounting tree and could speed up the booting time

 ## Simple Mount Details
-Some files require to be mounted much earlier in the boot process, currently known are bootanimation and some libs (most users won't change them). You can simply just place your files into the corresponding path under `/cache/magisk_mount`. At boot time, Magisk will **clone all the attributes of the target file**, including selinux contexts, permission mode, owner/group to the file, and bind mount to the target. You don't need to worry about the metadatas for files placed under `/cache/magisk_mount`.

-- **Windows users please aware!!** The line endings on all text files should be the **Unix format**. Please use advanced text editors like Sublime, Atom, Notepad++ etc., **NEVER** use Windows Notepad.
-- In `module.prop`, `version` can be an arbitrary string, so any fancy version name (e.g. ultra-beta-v1.1.1.1) is allowed. However, `versionCode` **MUST** be an integer. The value is used for version comparison.

+## Notes For Repo Developers
 
 - Magisk Manager monitors all repo's `master` branch. Any changes to the branch `master` will be reflected to all users immediately. If you are working on an update for a module, please work on another branch, make sure it works, then finally merge the changes back to `master`.
-- Once you finished upgrading your repo, bump up at least the `versionCode` in `module.prop`, so Magisk Manager will know you module is updated!
+- Once you finished upgrading your repo, increase at least the `versionCode` in `module.prop`. Magisk Manager uses this value to compare with the local installed module to determine whether an update is availible.
 - The description of your repo should be the same as your module ID. If you changed your description, Magisk Manager will fail to identify your repo, and cannot relate installed module to the online repo together.
