-### How Memory Allocations are Recorded
-
-The Memory Manager is the component that **"knows"** about the memory objects (allocations) in your Trick simulation. For each of these objects the Memory Manager stores the following **"knowledge"** :
-
-1. **Name** - optional, but **STRONGLY** recommended.
-2. **Address** - the address of the memory allocation.
-3. **Storage-class** - this is either
- 	* **TRICK\_LOCAL** for memory that is allocated by the Memory Manager, or
-	* **TRICK\_EXTERN** for memory that is allocated outside the Memory Manager that the Memory Manager is "told" about.
-4. **Data-type** is
-	* Primitive type specifier (```TRICK_DOUBLE```, ```TRICK_INT```, ... etc.) , or
-	* Composite type specifier (```TRICK_STRUCTURED```). In this case the details of the type are specified by an ```ATTRIBUTES``` structure that is generated by Trick's Interface Code Generator (ICG).
-
-<a id=trick-object-serialization></a>
-### Trick Object Serialization
-
-The Memory Manager can convert (ie., serialize) any of the objects that it **"knows"** about to a portable, human-readable text representation, to the extent that it knows about them (ICG can only gather data-type knowledge from header files that it has scanned.) The object can later be re-created from this representation. The represention consists of:
-
-1. A **definition** of the allocation, and 
-2. **value assignments** to each of the members of the allocations data type.
-
-#### Example:
-
-Suppose one were to perform the following allocation: 
-
-```double *dbl_p = (double*)TMM_declare_var_s("double dbl_array[3]");```
-
-The Memory Manager would represent its **definition** as follows in a checkpoint :
+# Trick CheckPointing Best Practices
 
-```
-double dbl_array[3];
-```

+double dbl_array[3];
+```
+

+
+```
     dbl_p[0] = 1.1;
     dbl_p[1] = 2.2;
     dbl_p[2] = 3.3;
-```
-
+```
+
 then the Memory Manager would represent its **variable assignment** as follows in a checkpoint :
-
-```
+
+```
 dbl_array = 
     {1.1, 2.2, 3.3};
-```
-<a id=serialization-of-composite-objects></a>
-#### Serialization of Composite Objects
-For composite type objects (i.e., class & struct objects), the **variable assignment** can consist of many assignment statements. Trick check-pointing code recursively descends into the composite type-tree, writing an assignment statement for each of the primitive data-typed members (leaves).
-
-<a id=serialization-of-pointers></a>
-#### Serialization of Pointers
-A pointer contains an address of another object. What's important is that it **refers** to the other object. We can't store the address of the object, because it will probably be different when the object is re-created at checkpoint reload. But, a **name** is also a reference. So we store pointers as names. Since objects have a name, and an address (once it's re-created) we can restore pointers by converting the name reference back to an address reference.
-
-<a id=importance-of-naming-allocations></a>
-#### Importance of Naming Allocations
-If an object is named, then that name will be used in checkpointing, 1) to identify and 2) to refer (point) to the object. If the object is anonymous then a temporary name must be created for checkpointing. These temporary names are of the form ```trick_anon_local_<number>``` or ```trick_anon_extern_<number```. They can't be as descriptive as a name you might chose so, it's a good idea to name your allocations when possible. It will be a lot easier to find them in a checkpoint file.
-
-<a id=simulation-checkpointing></a>
-### Simulation Checkpointing
-
-A **checkpoint** is a persistent representation of a simulation state. It's exactly like a "saved computer game" when it's time for dinner.
-
-If the Trick Memory Manager **"knows"** about all of the allocations that comprise the state of a simulation, then it can checkpoint that simulation. The Trick Memory Manager checkpoints a simulation by :
-
-1. Opening a checkpoint file.
-1. Writing all the **definitions**, of all of the objects that it knows about, to the file.
-2. Writing ```clear_all_vars();``` to the file. This is interpreted when the checkpoint is re-loaded, to initialize the re-created objects.
-3. Writing all the **variable assignments** to the file. These will populate the values of the object when the checkpoint is re-loaded.
-4. Closing the file.
-  
-There are certain things that simply cannot be checkpointed like file-pointers, and network connections. Perhaps there are other things as well. For these situations, Trick provides four special job classes: ```"checkpoint"```, ```"post_checkpoint"```, ```“preload_checkpoint”```, and ```“restart”``` (described below).
-
-<a id=dumping-a-checkpoint></a>
-### What Happens When You Dump a Checkpoint
-
-A checkpoint of a simulation is usually initiated from the Input Processor. That is, via:
-
-1. The input file, or
-2. The variable server.
- 
-```trick.checkpoint( <time> )``` is called from Python. This Python function is bound to the corresponding C++ function. At a simulation frame boundary (so that data is time-homogeneous), three things happen:
-
-1. The ```"checkpoint"``` jobs in the S_define file are executed. These job-classes allow you to prepare your sim to be checkpointed. Perhaps you want to transform simulation state data into a different form for checkpointing. This is up to you.
-
-2. ```write_checkpoint( <filename> )``` is called. This writes the three sections of a checkpoint file as described above.
-	
-3. The ```"post_checkpoint"``` jobs are called. This too is an opportunity for your simulatiion to tidy up what you may have done in your ```"checkpoint"``` job. 
-
-<a id=loading-a-checkpoint></a>
-### What Happens When You Load a Checkpoint.
-Trick.load_checkpoint() is called from Python.
-At a simulation frame boundary, three things happen:
-
-1. The ```“preload_checkpoint”``` jobs are called. These job-classes allow you to prepare your sim for a checkpoint-restore, in whatever way you see fit.
- 
-2. ```init_from_checkpoint( <filename> )``` is called, which:
-
-	1. Calls ```reset_memory``` to delete all dynamically allocated objects.
-	2. Calls ```read_checkpoint( <filename> )``` to read, parse, and restore the state described in the checkpoint file.
-		* Read the **definitions** section of the checkpoint file, and allocate all of the objects described there in.
-		* Clear all of the objects to 0, as appropriate to the data-type.
-		* Read the **assignment statement section**, and assign values to the objects.
-
-3. Run the ```“restart”``` jobs. These too are user-defined jobs that “tidy up” the simulation state. For example, this is where files might be re-opened, or socket connections are re-established. Again, what this does is up to the sim designer.
- 
-<a id=guidelines></a>
-## Do's and Don'ts
-* Plan for, and test that your models are checkpointable. Don't let this be an after-thought. Just like testing, if this is done from the beginning the pain suffering you’ll endure will be greatly reduced.
-
-* Keep data types no more complicated than they need to be. Remember the KISS principle.
-
-* If [I/O specification](https://nasa.github.io/trick/tutorial/ATutAnalyticSim#the-inputoutput-io-specification) of a data member is ```**``` then it will not be saved in a checkpoint. 
-
-* Don't make anonymous allocations in the input file. Naming them will make it much easier to find them later.
-
-* If you want your allocated objects to be checkpointed, allocate them with Memory Manager functions like: ```TMM_declare_var```, ```TMM_declare_var_1d```, and ```TMM_declare_var_s```.
-
-* If you use the ```new``` or ```malloc``` to allocate memory, the trick memory manager will have no knowledge of the memory allocation and will not checkpoint it. In order to make trick aware, you need to use a trick memory manager function to allocate (as above) or use ```declare_extern_var```.
-
-* In the case where you use ```declare_extern_var```, it's important to remember that that Trick will not delete nor restore objects that it did not allocate. It does not know how **extern** memory was allocated ( Note that ```new``` and ```malloc``` are not the only ways to allocate memory ). You are still responsible for de-allocation at the appropriate time.
