 * We use merge to add the commits from a PR/branch to master
-* Smaller PRs may be squashed before merging (especially if the commit history
-on them isn't valuable), but when in doubt prefer merging
-* Manual merging may be done by a Maintainer if there are technical problems
-with the branch, with Gitea, or the PR had been merged to from master and
-the author can't fix it for whatever reason
-* PR from a fork (usually the author has no contributor/developer privileges)
-can be retargeted and merged first into a buffer (normal new) branch on the repo
-when adopted by a Developer, and only later into master
 * Submodules should only be used if a) upstream is highly reliable and
-b) it is 100% certain that no VL specific changes to the code will be
-needed (this has never been the case before, hence VL is submodule free so far)
-* Subtrees may be used for including outside mods that don't need changes
-in the foreseeable future
+b) it is 100% certain that no mcl2 specific changes to the code will  be
+needed (this has never been the case before, hence mcl2 is submodule free so far)
 * Commit messages should be descriptive
 * Try to group your submissions best as you can:
-  * Try to keep your PRs small: In some cases things reasonably be can't

+* Avec une priorité moindre, implémenter les fonctionnalités des versions **Minecraft + OptiFine** (OptiFine autant que supporté par le moteur Minetest). Cela signifie que les fonctionnalités présentes dans les versions listées sont priorisées.
+* Dans l'idéal, créer une expérience performante qui tourne bien sur des ordinateurs à basse performance.

+* Create release branch from the last release tag, push it:
 
-## Hotfix Release
-
-### Before releasing
-
-First, determine if the current state of the master branch is fine for the Hotfix.
-In general, Hotfixes shouldn't contain new features to minimize the risk of regressions.
-
-* If it hasn't been long since the release, and the only PRs merged so far are bugfixes and/or documentation changes,
-it is certainly fine to use it as a base for the release.
-* If there are some features merged, but they are aimed at fixing/alleviating important issues with the last released version, it may still be fine.
-* If there are some simple QoL features merged that are irrelevant to the last release, it may still be fine to use it as a base for the Hotfix.
-* If there are major features or large overhauls merged, it *most probably* is **not** fine to use as a base for the Hotfix.
-
-If you decided that the current state of the master branch can be used as the Hotfix version, make sure that all the PRs merged since the last release
-are in the Hotfix milestone and you are working on a clean branch based on the master branch, up-to-date with the one on the repo.
-In this case, **skip** the following section.
-
-### Prepare release branch
-
-If you decided that the current state of the master branch shouldn't be used as the Hotfix version, you must prepare a release branch.

-2. Cherry-pick the relevant commits from the master branch, or merge them from other (PR) branches.
-3. Make sure your local copy of the branch contains all the relevant changes, **do not rebase**.
 
-### Release process
+##### Prepare feature branch and fix
 
-1. Update CREDITS.md if it is needed
-2. Update version in game.conf
-3. If you've changed CREDITS.md, run the script:
-```
-lua tools/generate_ingame_credits.lua
-```
-4. Make a commit for the above:
-```
-git add game.conf
-git commit -m "Set version for hotfix v0.87.1"
-```
-or, if credits got updated:
-```
-git add CREDITS.md
-git add mods/HUD/mcl_credits/people.lua
-git add game.conf
-git commit -m "Updated release credits and set version for hotfix v0.87.1"
-```
-5. Add a section in the last releasnotes, like this:
-```
-## 0.87.1 hotfix
-```
-and describe the changes there
+* Create feature branch from that release branch (can review it to check only fix is there, nothing else, and use to also merge into master separately)
+
+`git checkout -b hotfix_bug_1_branch`
+
+* Fix crash/serious bug and commit
+* Push branch and create pr to the release and also the master branch (Do not rebase, to reduce merge conflict risk. Do not delete after first merge or it needs to be repushed)
+
+##### Update version and tag the release
+
+* After all fixes are in release branch, pull it locally  (best to avoid a merge conflict as feature branch will need to be merged into master also, which already changed version):
+
+* Update version in game.conf to hotfix version and commit it. Example: version=0.82.1
+
+* Tag it, push tag and branch:
 
-6. Make a commit for the releasenotes changes:
-```
-git add releasenotes/0_87-the_prismatic_release.md
-git commit -m "Update release notes for hotfix v0.87.1"
-```
-7. **Tag and push to the tag:**
-```
-git tag 0.87.1
-git push origin 0.87.1
-```
-8. If you are skipping some changes from the master branch (and thus are using a prepared master branch from the previous section),
-push to the remote and skip the next two steps:
 ```
+git tag 0.82.1
+
+git push origin 0.82.1
+
 git push origin release/0.82.1
 ```
-9. If you're releasing master branch, update version in game.conf to the next version with -SNAPSHOT suffix:
-```
-git commit -m "Post-hotfix reset version 0.88.0-SNAPSHOT"
-```
-10. If you're releasing master branch, push the above to a new branch, and make the release PR. Merge to finalize release process.
+
+Note: If you have to do more than 1 hotfix release, can do it on the same release branch.

+
+- `node_position` - the location of the node to calculate adjacency for.
+- `options` - A table containing any of these options:
+  - `legacy`- if true, don't check that a connection proceeds out in a direction

+    the neighboring node from this direction.
+
+`mcl_minecarts:is_rail(position, railtype)`
+
+Determines if the node at `position` is a rail. If `railtype` is provided,
+determine if the node at `position` is that type of rail.

+
+## Cart-Node Interactions
+
+As the cart moves thru the environment, it can interact with the surrounding blocks
+thru a number of handlers in the block definitions. All these handlers are defined
+as:
+
+`function(node_position, cart_luaentity, cart_direction, cart_position)`
+
+Arguments:
+- `node_position` - position of the node the cart is interacting with
+- `cart_luaentity` - The luaentity of the cart that is entering this block. Will
+   be nil for minecarts moving thru unloaded blocks
+- `cart_direction` - The direction the cart is moving
+- `cart_position` - The location of the cart
+- `cart_data` - Information about the cart. This will always be defined.
+
+There are several variants of this handler:
+- `_mcl_minecarts_on_enter` - The cart enters this block
+- `_mcl_minecarts_on_enter_below` - The cart enters above this block
+- `_mcl_minecarts_on_enter_above` - The cart enters below this block
+-  `_mcl_minecarts_on_enter_side` - The cart enters beside this block
+
+Mods can also define global handlers that are called for every node. These
+handlers are defined as:
+
+`function(node_position, cart_luaentity, cart_direction, node_definition, cart_data)`
+
+Arguments:
+- `node_position` - position of the node the cart is interacting with
+- `cart_luaentity` - The luaentity of the cart that is entering this block. Will
+   be nil for minecarts moving thru unloaded blocks
+- `cart_direction` - The direction the cart is moving
+- `cart_position` - The location of the cart
+- `cart_data` - Information about the cart. This will always be defined.
+- `node_definition` - The definition of the node at `node_position`
+
+The available hooks are:
+- `_mcl_minecarts.on_enter` - The cart enters this block
+- `_mcl_minecarts.on_enter_below` - The cart enters above this block
+- `_mcl_minecarts.on_enter_above` - The cart enters below this block
+- `_mcl_minecarts.on_enter_side` - The cart enters beside this block
+
+Only a single function can be installed in each of these handlers. Before installing,
+preserve the existing handler and call it from inside your handler if not `nil`.
+
+## Train Functions
+
+`mcl_minecarts.break_train_at(cart_data)`
+
+Splits a train apart at the specified cart.
+
+`mcl_minecarts.distance_between_cars(cart1_data, cart2_data)`

+`mcl_minecarts.is_in_same_train(cart1_data, cart2_data)`
+
+Returns true if cart1 and cart2 are a part of the same train and false otherwise.
+
+`mcl_minecarts.link_cart_ahead(cart_data, cart_ahead_data)`
+
+Given two carts, link them together into a train, with the second cart ahead of the first.
+
+`mcl_minecarts.train_cars(cart_data)`
+
+Use to iterate over all carts in a train. Expected usage:
+

+
+## Rail Nodes
+
+Previous versions of mcl\_minecarts used one node type for each rail type (standard,
+powered, detector and activator) using the raillike draw type that minetest provides.
+This version does not use the raillike draw type and instead uses a 1/16th of a block
+high nodebox and uses an additional node definition for each variant. The variants
+present are:
+
+- straight
+- sloped
+- corner
+- tee
+- cross
+
+Of the rail types provided by this module, standard has all of these variants. The
+remaining types only have straight and sloped variants.
+
+Unlike the old rail type, this version will only update connections when placed, and
+will only place a variant that already has connections into the space the rail is
+being placed. Here is how to create the various varients:
+
+- Straight rail is placed when with zero or one adjacent rail nodes. If no rails
+  are adjacent, the rail is placed in line with the direction the player is facing.
+  If there is exactly one adjacent rail present, the straight rail will always rotate
+  to connect to it.
+
+- Sloped rail is placed when there are two rails in a straight line, with one being
+  one block higher. When rail is placed adjacent to a straight rail one block lower
+  and the rail is facing the block the rail is being placed on, the lower rail will
+  convert into a slope.
+
+- A corner rail is placed when there are exactly two adjacent rails that are not in
+  a line and lead into the space the rail is being placed. The corner will be rotated
+  to connect these two rails.
+
+- A tee rail is placed where there are exactly three rails adjact and those existing
+  rails lead into the the space the new rail is being placed.
+
+- A rail cross is placed when there is rail in all four adjacent blocks and they all
+  have a path into the space the new rail is being placed.
+
+The tee variant will interact with redstone and mesecons to switch the curved section.
+
+## On-rail Minecart Movement
+
+Minecart movement is handled in two distinct regimes: on a rail and off. The
+off-rail movement is handled with minetest's builtin entity movement handling.
+The on-rail movement is handled with a custom algorithm. This section details
+the latter.
+
+The data for on-rail minecart movement is stored entirely inside mod storage
+and indexed by a hex-encoded 128-bit universally-unique identifier (uuid). Minecart
+entities store this uuid and a sequence identifier. The code for handling this
+storage is in [storage.lua](./storage.lua). This was done so that minecarts can
+still move while no players are connected or when out of range of players. Inspiration
+for this was the [Advanced Trains mod](http://advtrains.de/). This is a behavior difference
+when compared to minecraft, as carts there will stop movement when out of range of
+players.
+
+Processing for minecart movement is as follows:
+1. In a globalstep handler in [carts.lua](./carts.lua), determine which carts are
+   moving.
+2. Call `do_movement` in [movement.lua](./movement.lua) to update
+   each cart's location and handle interactions with the environment.
+   1. Each movement is broken up into one or more steps that are completely
+      contained inside a block. This prevents carts from ever jumping from
+      one rail to another over a gap or thru solid blocks because of server
+      lag. Each step is processed with `do_movement_step`
+   2. Each step uses physically accurate, timestep-independent physics
+      to move the cart. Calculating the acceleration to apply to a cart
+      is broken out into its own function (`calculate_acceperation`).
+   3. As the cart enters and leaves blocks, handlers in nearby blocks are called
+      to allow the cart to efficiently interact with the environment. Handled by
+      the functions `handle_cart_enter` and `handle_cart_leave`
+   4. The cart checks for nearby carts and collides elastically with these. The
+      calculations for these collisions are in the function `handle_cart_collision`
+   5. If the cart enters a new block, determine the new direction the cart will
+      move with `mcl_minecarts:get_rail_direction` in [functions.lua](./functions.lua).
+      The rail nodes provide a hook `_mcl_minecarts.get_next_direction` that
+      provides this information based on the previous movement direction.
+3. If an entity exists for a given cart, the entity will update its position
+   while loaded in.
+
+Cart movement when on a rail occurs regarless of whether an entity for that
+cart exists or is loaded into memory. As a consequence of this movement, it
+is possible for carts with unloaded entities to enter range of a player.
+To handle this, periodic checks are performed around players and carts that
+are within range but don't have a cart have a new entity spawned.
+
+Every time a cart has a new entity spawned, it increases a sequence number in
+the cart data to allow removing old entities from the minetest engine. Any cart
+entity that does not have the current sequence number for a minecart gets removed
+once processing for that entity resumes.
